Stem cell study finds source of earliest blood cells during development

Friday, March 21st, 2014

PUBLIC RELEASE DATE:

Contact: Matthew Inlay minlay@uci.edu 949-824-8226 University of California - Irvine

Irvine, Calif., March 20, 2014 Hematopoietic stem cells are now routinely used to treat patients with cancers and other disorders of the blood and immune systems, but researchers knew little about the progenitor cells that give rise to them during embryonic development.

In a study published April 8 in Stem Cell Reports, Matthew Inlay of the Sue & Bill Gross Stem Cell Research Center and Stanford University colleagues created novel cell assays that identified the earliest arising HSC precursors based on their ability to generate all major blood cell types (red blood cells, platelets and immune cells).

This discovery of very early differentiating blood cells, Inlay said, may be very beneficial for the creation of HSC lines for clinical treatments.

"The hope is that by defining a set of markers that will allow us to make purer, cleaner populations of these precursor cells, we'll be able to reveal the key molecular events that lead to the emergence of the first HSCs in development. This could give us a step-by-step guide for creating these cells in a dish from pluripotent stem cell lines" added Inlay, who is an assistant professor of molecular biology & biochemistry at UC Irvine and conducted the study while a postdoctoral researcher in the Irving Weissman lab in the Institute for Stem Cell Biology and Regenerative Medicine at Stanford University.

The work was performed in collaboration with Thomas Serwold, now an assistant professor in the Joslin Diabetes Center at Harvard Medical School.

The research reported in this article was supported by the National Institutes of Health (grants 5 T32 AI07290, R01HL058770, R01CA86085 and U01HL09999), the California Institute for Stem Cell Research (grants T1-00001, RT2-02060 to I.L.W.), the Harvard Stem Cell Institute, the Siebel Stem Cell Institute, the Thomas and Stacey Siebel Foundation, and the Virginia and D.K.

A*STAR scientists create stem cells from a drop of blood

Thursday, March 20th, 2014

PUBLIC RELEASE DATE:

20-Mar-2014

Contact: Tan Yun Yun tan_yun_yun@a-star.edu.sg 656-826-6273 Biomedical Sciences Institutes (BMSI)

1. Scientists at A*STAR's Institute of Molecular and Cell Biology (IMCB) have developed a method to generate human induced pluripotent stem cells (hiPSCs) from a single drop of finger-pricked blood. The method also enables donors to collect their own blood samples, which they can then send to a laboratory for further processing. The easy access to blood samples using the new technique could potentially boost the recruitment of greater numbers and diversities of donors, and could lead to the establishment of large-scale hiPSC banks.

2. By genetic reprogramming, matured human cells, usually blood cells, can be transformed into hiPSCs. As hiPSCs exhibit properties remarkably similar to human embryonic stem cells, they are invaluable resources for basic research, drug discovery and cell therapy. In countries like Japan, USA and UK , a number of hiPSC bank initiatives have sprung up to make hiPSCs available for stem cell research and medical studies.

3. Current sample collection for reprogramming into hiPSCs include invasive measures such as collecting cells from the bone marrow or skin, which may put off many potential donors. Although hiPSCs may also be generated from blood cells, large quantities of blood are usually required. In the paper published online on the Stem Cell Translational Medicine journal, scientists at IMCB showed for the first time that single-drop volumes of blood are sufficient for reprogramming into hiPSCs. The finger-prick technique is the world's first to use only a drop of finger-pricked blood to yield hiPSCs with high efficiency. A patent has been filed for the innovation.

4. The accessibility of the new technique is further enhanced with a DIY sample collection approach. Donors may collect their own finger-pricked blood, which they can then store and send it to a laboratory for reprogramming. The blood sample remains stable for 48 hours and can be expanded for 12 days in culture, which therefore extends the finger-prick technique to a wide range of geographical regions for recruitment of donors with varied ethnicities, genotypes and diseases.

5. By integrating it with the hiPSC bank initiatives, the finger-prick technique paves the way for establishing diverse and fully characterised hiPSC banking for stem cell research. The potential access to a wide range of hiPSCs could also replace the use of embryonic stem cells, which are less accessible. It could also facilitate the set-up of a small hiPSC bank in Singapore to study targeted local diseases.

6. Dr Loh Yuin Han Jonathan, Principal Investigator at IMCB and lead scientist for the finger-prick hiPSC technique, said, "It all began when we wondered if we could reduce the volume of blood used for reprogramming. We then tested if donors could collect their own blood sample in a normal room environment and store it. Our finger-prick technique, in fact, utilised less than a drop of finger-pricked blood. The remaining blood could even be used for DNA sequencing and other blood tests."

7. Dr Stuart Alexander Cook, Senior Consultant at the National Heart Centre Singapore and co-author of the paper, said "We were able to differentiate the hiPSCs reprogrammed from Jonathan's finger-prick technique, into functional heart cells. This is a well-designed, applicable technique that can unlock unrealized potential of biobanks around the world for hiPSC studies at a scale that was previously not possible."

MANILA - Five doctor-incorporators of the Philippine Society for Stem Cell Medicine (PSSCM) face charges and may have their medical licenses revoked for submitting a fabricated endorsement from the Professional Regulation Commission (PRC) to the Securities and Exchange Commission (SEC).

Among them are chairman of the Philippine Medical Association Leo Olarte, PSSCM treasurer and legal counsel; Bu Castro, secretary; Rey Melchor Santos, president; Oscar Tinio, vice president; and Jose Asa Sabili, chairman.

In a statement, PRC Chairperson Teresita Manzala on Sunday said she directed the Professional Regulatory Board of Medicine (PRBOM) to initiate, investigate, and file charges against the five doctors before the PRCs legal division for unprofessional, dishonorable, and unethical conduct.

Earlier on 10 January 2014, the SEC cancelled the registration of the PSSCM for submitting a fabricated document. In an order signed by SEC Acting Director Ferdinand Sales, the commission said the PSSCM had committed fraud in procuring its Certificate of Incorporation for its application for corporate registration.

Wherefore, premises considered, the Certificate of Registration of Philippine Society for Stem Cell Medicine with SEC Registration No. CN201303986, approved on March 6, 2013 is hereby revoked, the order reads.

Falsified endorsement

SEC said PSSCM submitted a 2ndPRC Indorsement, dated 20 February 2013, supposedly from Manzala. But on14 August 2014, SEC received a letter-complaint from Manzala informing the commission that the signature appearing in the alleged favorable indorsement from PRC was not hers and, thus, falsified.

Stem cell politics behind forgery chargesPMA president

Monday, March 17th, 2014

Leo Olarte, M.D., PMA president. PHOTO from http://www.philippinemedicalassociation.org

MANILA, Philippines Politics over stem cell treatment may be behind the move to slap an ethics case against him for allegedly falsifying signatures, the Philippine Medical Association (PMA) president said.

In an interview over Inquirer Radio 990 AM on Monday, Dr. Leo Olarte said he found it suspicious that Professional Regulation Commission (PRC) Chair Teresita Manzala announced the ethics case against him on the day of the elections for the next PMA president.

He claimed Manzala slapped the ethics case before the PRC to ruin his chances of being re-elected in the countrys largest doctors association.

Olarte said Manzala has connections to doctors who are against stem cell medicine. Olarte is a supporter of stem cell treatment.

Manzala released the statement on the day of our elections specifically to destroy my name Manzala (also) has connections to doctors who are against stem cell. I am pro-stem cell treatment while my rival (for president) is not, Olarte said in Filipino.

In a Philippine Daily Inquirer report on Sunday, Olarte and his four predecessors were charged with fraud in the registration of the Philippine Society for Stem Cell Medicine (PSSCM) in the Securities and Exchange Commission.

Olarte and the four others Bu Castro, Rey Melchor Santos, Oscar Tinio and Jose Sabili were accused of forging Manzalas signature in an endorsement for the incorporation of the PSSCM.

But Olarte blamed a syndicate behind the alleged forgery.

He said the PMA paid a private trading company to process the PSSCMs incorporation with the SEC. The doctor did not name the company.

5 doctors charged with falsifying papers to get certificate for stem cell group

Monday, March 17th, 2014

PRC: Stem cell group submitted fake SEC registration. At a press conference in Manila on Monday, March 17, Professional Regulation Commission chairperson Teresita Manzala said the PRC endorsement documents allegedly submitted by the Philippine Society for Stem Cell Medicine (PSSCM) to the Securities and Exchange Commission (SEC) were fabricated and have her tampered signature. The SEC previously revoked the corporate registration of the PSSCM. Danny Pata

In a statement, Professional Regulation Commission (PRC) chair Teresita Manzala said she has asked the Professional Regulatory Board of Medicine (PRBOM) to initiate, investigate and file charges against doctors Leo Olarte, Bu Castro, Rey Melchor Santos, Oscar Tinio and Jose Asa Sabili before the PRCs legal division.

Olarte is the current president of the PMA.

The five doctors are all incorporators of the Philippine Society for Stem Cell Medicine (PSSCM,) which was able to obtain an SEC certificate despite previously being denied corporate registration. They were able to do this, said the statement, by submitting false PRC endorsements to the commission.

The PRBOM eventually got hold of a copy of the SEC Registration. On examination of the supposed PRC Endorsement, it was noted that the reference regulatory law used was the Philippine Veterinary Law of 2004, instead of Republic Act 2382, otherwise known as the Medical Act of 1959, and there appeared a signature of the PRC Chairperson, the PRC statement said.

Manzala said complaints were filed against the doctors for unprofessional, dishonorable and unethical conduct.

According to the statement, the incorporators later denied participation in obtaining the SEC registration, instead naming a Dr. Mike Aragon as the person who obtained the certification.

In a notarized affidavit submitted to the PRBOM, 'Dr. Mike Aragon' declared that he was the person authorized to register a corporation to be called 'Philippine Society for Stem Cell Medicine' and admitted paying 15,000 pesos to a trading company for them to file the necessary documents for incorporation of the PSSCM, the PRC statement said.

But Aragon claimed to have had no participation whatsoever in the actual processing of the SEC papers for incorporating the PSSCM. Patricia Denise Chiu/BM, GMA News

Registration of PH stem cell group revoked

Sunday, March 16th, 2014

MANILA - The Securities and Exchange Commission (SEC) revoked the corporate registration of the Philippine Society for Stem Cell Medicine (PSSCM) for submitting fabricated endorsement from the Professional Regulation Commission (PRC).

In a five-page order, SEC acting director Ferdinand Sales said the PSSCM committed fraud in procuring its Certificate of Incorporation.

He said that as required under Section 17 of the Corporation Code, the PSSCM submitted a favorable endorsement from the PRC to support its application for corporate registration.

But he said the SEC found that the 2nd PRC Indorsement dated Feb. 20, 2013 submitted by PSSCM was falsified.

Considering the submission of a falsified PRC endorsement, there is fraud in procurement of respondents certificate of registration. The falsified document was relied upon by this Commission in approving the registration application of the respondent, Sales noted.

He added that had the SEC known about such defect early on, it would have not accepted and approved the registration application of the respondent.

New cell line should accelerate embryonic stem cell research

Friday, March 14th, 2014

University of Washington researchers have created a line of human embryonic stem cells with the ability to develop into a far broader range of tissues than most existing cell lines.

"These cells will allow us to gain a much greater understanding of normal embryonic development and have the real potential for use in developing ways to grow new tissues and organs for transplantation," said Carol Ware, a professor of comparative medicine. She is the lead author of a paper describing the new cell line.

The findings are reported in the March 10 issue of the journal Proceedings of the National Academy of Sciences. The cells, called nave embryonic stem cells, normally appear at the earliest stages of embryonic development. They retain the ability to turn into any of all the different types of cells of the human body -- a capacity called "pluripotency."

Researchers had been able to develop nave cells using mouse embryonic stem cells, but to create naive human embryonic stem cells has required inserting a set of genes that force the cells to behave like naive cells.

While these transgenic cells are valuable research tools, the presence of artificially introduced genes meant the cells will not develop as normal embryonic cells would nor could they be safely used to create tissues and organs for transplantation.

In an article, Ware and her colleagues from the UW Institute for Stem Cell and Regenerative Medicine describe how they successfully created a line of nave human embryonic stem cells without introducing an artificial set of genes.

They first took embryonic stem cells that are slightly more developed, called primed stem cells, and grew them in a medium that contained factors that switched them back -- or "reverse toggled" them -- to the nave state. They then used the reverse toggled cells to develop a culture medium that would keep them in the nave state and create a stable cell line for study and research.

While the "reverse toggled" cells are much easier to create and will prove valuable research tools, Ware said, the cells that were directly derived from embryos are the more important advance because they are more likely to behave, grow and develop as embryonic cells do in nature.

The new cell line is called Elf1: "El" for the Ellison Foundation, a major supporter of the lab's work; "f" for female, the sex of the stem cell; and "1" for first.

DaSilva Institute of Anti-Aging, Regenerative & Functional Medicine Offers Autologous Stem Cell Therapy for Men …

Wednesday, March 12th, 2014

Sarasota, FL (PRWEB) March 12, 2014

Erectile dysfunction (ED) is the most commonly studied disorder when it comes to male sexual dysfunction. It is estimated that 18 million men in the US alone suffer from erectile dysfunction and that it appears to be affecting 1 in 4 males under age 40 according to a study published in The Journal of Sexual Medicine.

While the emphasis of treatments for ED focuses on relieving the symptoms, they only provide a temporary solution rather than a cure or reversing the cause.

The DaSilva Institute is excited to announce the recruitment of males suffering from ED, in an IRB study, which will look at the safety, and efficacy of autologous, adipose derived stem cells (ADSCs) in regenerating the causes of ED.

The evidence shows that ADSCs reverses the pathophysiological changes leading to ED, rather than treating the symptoms of ED. Not only is the data in the literature compelling, but our own, in-house, results on our patients have been phenomenal, states Dr. DaSilva.

The many underlying causes for ED that are being investigated range from those secondary to aging, to injury of the cavernous nerve secondary to injury, surgery and/or radiation of the prostate, to diabetic ED and Peyronies Disease to name a few. According to Dr. DaSilva, the possibilities for ADSCs in reversing ED are limitless.

Currently, there is an expansive and growing body of evidence in the medical literature strongly indicating that ADSCs might be a potential cure for ED, rather than merely symptom relief, which is indicative of the increasing interest in ADSC-regenerative options for sexual medicine over the past decade. The DaSilva Institutes goal is to take this from pre-clinical studies to the clinical world offering it to all males that suffer from intractable ED under an IRB approved protocol.

More information about Dr. DaSilva and the DaSilva Institute Guy DaSilva, MD is currently the medical director of the DaSilva Institute of Anti-Aging, Regenerative & Functional Medicine, located in Sarasota, Florida. Dr. DaSilvas enthusiasm for using autologous stem cells in regenerative medicine comes from his early days as a pathologist in New York City back in 1987 and later as a fellow in hematology in1990 following his residency in internal medicine.

He later brought his expertise in molecular and cellular medicine to the University of Kansas Medical Center where he served as chief of Hematology & Hematopathology. He later became the CEO and medical director of HemePath Institute, a diagnostic leader in diagnosing the most difficult cases of leukemia and lymphomas. Most recently, Dr. DaSilva teamed up with one of the most influential stem cell scientist in the world to bring the highest quality and viability of the harvested stem cells, bar none, to the DaSilva Institute.

Dr. DaSilva is board certified and fellowship trained in Anti-Aging and Regenerative Medicine. For more information about Dr. DaSilva or the DaSilva Institute go to http://www.dasilvainstitute.com.

Miami Stem Cell Treatment Center: What The Stem Cell Procedure Entails and An Invitation To MSCTC Public Seminar; Meet …

Wednesday, March 12th, 2014

Boca Raton, Florida (PRWEB) March 12, 2014

The Miami Stem Cell Treatment Center, PC, located in Miami, Ft. Lauderdale, and Boca Raton, Florida, offers a free public seminar on the use of stem cells for various degenerative and inflammatory conditions. They will be provided by Dr. Thomas A. Gionis, Surgeon-in-Chief, and, Dr. Nia Smyrniotis, Medical Director. The next upcoming seminar will be held on March 16th at the Comfort Suites Weston, 2201 N. Commerce Parkway, Weston, Florida 33326, at 2pm.

Regenerative Medicine: Our Procedure The Miami Stem Cell Treatment Center uses Autologous Adult Adipose Stem Cells to provide care for patients suffering from chronic conditions that may benefit from adult stem cell-based regenerative medicine.

The Miami Stem Cell Treatment Center follows the regenerative medicine procedures developed by the California Stem Cell Treatment Centers (CSCTC) and Cell Surgical Network (CSN) which involves the initial screening, examination and evaluation of every potential candidate for stem cell investigational therapy by one of our physicians. Once a patient is deemed to be an appropriate candidate, the procedure itself is performed by our Surgeon-in-Chief, who is assisted by a team of experienced surgical team members and surgical technicians. The entire process from start to finish takes less than two hours. It is relatively painless, and recovery time is minimal.

In recent times, the bone marrow has been a source for stem cells. Taking bone marrow, however, is a painful procedure. Fat, however, contains many times more stem cells than bone marrow and is much easier and safer to harvest.

For many disease types such as cardiac pathology, adipose derived cells appear to be showing superiority to bone marrow derived cells. This may be related to the well documented fact that chronic disease causes bone marrow suppression. Fat derived cells are a natural choice for our investigational work considering their easy and rapid availability in extremely high numbers.

With our current technology, we can harvest your own fat cells, digest the fat cells and separate out the stem cells. The most significant advantage of using your fat as a source for the stem cells, is that the procedure can be done in the office in only a few hours, as the stem cells can be ready for injection after only 60 minutes of processing with our state of the art equipment. Your stem cells do NOT need to be sent out for processing and there is no need for you to travel outside of the U.S. to have them injected.

Indeed, adipose tissue is an abundant source of mesenchymal stem cells, which have shown promise in the field of regenerative medicine. Furthermore, these cells can be readily harvested in large numbers with low donor-site morbidity. During the past decade, numerous studies have provided pre-clinical data on the safety and efficacy of adipose-derived stem cells, supporting the use of these cells in clinical applications. Various clinical trials have shown the regenerative capability of adipose-derived stem cells in numerous fields of medicine. In addition, a great deal of knowledge concerning the harvesting, characterization, and culture of adipose-derived stem cells has been reported.

Our current areas of study include: Heart Failure, Emphysema, COPD, Asthma, Parkinsons Disease, Stroke, Multiple Sclerosis, and orthopedic joint injections. . The investigational protocols utilized by the Miami Stem Cell Treatment Center have been reviewed and approved by an IRB (Institutional Review Board) which is registered with the U.S. Department of Research Protections; and the study is registered with http://www.Clinicaltrials.gov, a service of the U.S. National Institutes of Health (NIH).

Newswise COLUMBUS, Ohio -- Imagine a world where malfunctioning organs are replaced by new ones made from your own tissues, where infected wounds are cured with a signal from your smartphone, where doctors find the perfect medicine for whatever ails you simply by studying your stem cells.

Its a world thats inching closer to reality because of the work of some of the nations top scientists, many of whom will gather March 13-15 at The Ohio State University for the 7th Annual Translational to Clinical (T2C) Regenerative Medicine Conference to discuss their recent successes and challenges in coaxing the body to heal itself in extraordinary ways.

Regenerative medicine will change the way you and I experience sickness, health and healthcare, said Chandan Sen, director of the Center for Regenerative Medicine and Cell Based Therapies at Ohio States Wexner Medical Center. Because the field is so new, we as researchers are also changing the way we work to be synergistic not competitive, so patients are able to access the benefits more quickly.

And the benefits are desperately needed, says keynote speaker Dr. Anthony Atala, director of the Wake Forest Institute for Regenerative Medicine at Wake Forest Baptist Medical Center.

From chronic diseases such as kidney failure that costs billions of dollars each year to the medical needs of our aging population and the significant injuries sustained by military troops in Afghanistan, developing new treatment paradigms is essential, said Atala, who was selected to lead the $75 million Armed Forces Institute of Regenerative Medicine (AFIRM), a consortium of 30 academic and industry partners in applying regenerative medicine techniques to battlefield injuries.

In theory, every tissue in the body has the ability to regenerate and heal itself. Its good to come to this meeting and exchange ideas that will enable us to harness that remarkable ability.

Other speakers include Elaine Fuchs, Howard Hughes Medical Institute investigator and Rebecca C. Lancefield Professor at Rockefeller University in New York, who has advanced multiple areas of stem cell research through her work in skin cells and genetics; and Dr. Michael Longaker, director of the Hagey Laboratory for Stem Cell Biology for Pediatric Regenerative Medicine at Stanford University. Longaker is considered one of the nations experts in using a combination of stem cell- and bioengineering-based technologies for craniofacial reconstruction.

Several Ohio State College of Medicine and Wexner Medical Center clinician-scientists are also sharing research updates during pre-conference lectures and the meeting:

Stem Cell Researcher Suggests Recalling His Own Study

Tuesday, March 11th, 2014

By Maggie Fox

One of the worlds leading stem cell experts has suggested withdrawing a study that made global headlines last January, saying he has questions about some of the images and data in it.

The Japanese team, led by Teruhiko Wakayama, reported that they had created powerful stem cells by doing little more than soaking ordinary cells in an acid solution.

The report, published in the journal Nature, impressed other stem cell researchers and opened the possibility of an easy approach to regenerative medicine. But Japanese television quotes Wakayama as saying he wants to take a closer look.

"When conducting the experiment, I believed it was absolutely right, Reuters news agency quotes Wakayama as telling the television station NHK.

"But now that many mistakes have emerged, I think it is best to withdraw the research paper once and, using correct data and correct pictures, to prove once again the paper is right," he said.

"If it turns out to be wrong, we would need to make it clear why a thing like this happened."

But Charles Vacanti of Harvard Medical School and Brigham and Women's Hospital in Boston, who helped work on the study, said he disagreed. "Some mistakes were made, but they don't affect the conclusions," the Wall Street Journal quoted him as saying.

"Based on the information I have, I see no reason why these papers should be retracted."

Stem cell researchers may be more sensitive than other scientists. In 2006, Seoul National University fired Hwang Woo-Suk after the journal Science retracted two papers he wrote claiming to have cloned human embryos and extracted stem cells from them.

See Inside Mar 19, 2013 |By Christine Gorman

Richard Clark, NIH

Researchers are now experimenting with stem cellsprogenitor cells that can develop into many different types of tissueto coax the bodies of a few individuals to heal themselves. Some of the most advanced clinical trials so far involve treating congestive heart disease and regrowing muscles in soldiers who were wounded in an explosion. But new developments are happening so quickly that investigators have come up with a new nameregenerative medicineto describe the emerging field.

Many of the stem cells being studied are referred to as pluripotent, meaning they can give rise to any of the cell types in the body but they cannot give rise on their own to an entirely new body. (Only the earliest embryonic cells, which occur just after fertilization, can give rise to a whole other organism by themselves.) Other stem cells, such as the ones found in the adult body, are multipotent, meaning they can develop into a limited number of different tissue types.

One of the most common stem cell treatments being studied is a procedure that extracts a few stem cells from a person's body and grows them in large quantities in the laboratorywhat scientists refer to as expanding the number of stem cells. Once a sufficient number have been produced in this manner, the investigators inject them back into the patient.

The bone marrow is a rich source of adult stem cells, containing both the hematopoietic stem cells that give rise to the various types of blood and the so-called mesenchymal cells, which can develop into bone, cartilage and fat. Mesenchymal cells are found in the bone marrow and various other places in the body, although whether all mesenchymal stem cells are truly interchangeable irrespective of origin is unclear.

Scientific American spoke with Mahendra Rao, director of the Center for Regenerative Medicine at the National Institutes of Health in Bethesda, Md., to get a sense of the sorts of new developments that might occur in regenerative medicine in the next five years or so.

[An edited transcript of the interview follows.]

Why is there so much excitement about regenerative medicine? You could say that medicine up until now has been all about replacements. If your heart valve isn't working, you replace it with another valve, say from a pig. With regenerative medicine, you're treating the cause and using your own cells to perform the replacement. The hope is that by regenerating the tissue, you're causing the repairs to grow so that it's like normal.

Scientists Chafe at Restrictions on New Stem Cell Lines

Thursday, March 6th, 2014

The California Institute for Regenerative Medicine is rethinking its rules in the wake of a recent breakthrough involving the creation of stem cell lines from a cloned human embryo

OHSU Photos

The announcement last month of a long-awaited breakthrough in stem-cell research the creation of stem-cell lines from a cloned human embryo has revived interest in using embryonic stem cells to treat disease. But US regulations mean that many researchers will be watching those efforts from the sidelines.

The US National Institutes of Health (NIH), which distributes the majority of federal funding for stem-cell research, prohibits research on cells taken from embryos created solely for research a category that includes the six stem-cell lines developed by Shoukhrat Mitalipov, a reproductive-biology specialist at the Oregon Health and Science University in Beaverton, and his colleagues. The team used cloning techniques to combine a donor cell with an unfertilized egg whose nucleus had been removed, creating a self-regenerating stem-cell colony that is genetically matched to the cell donor.

Mitalipovs cell lines are also off limits to researchers funded by the California Institute for Regenerative Medicine (CIRM), which was created in part to support stem-cell work that is restricted by the NIH. CIRM funds cannot be used for studies that pay women for their eggs or rely on cell lines produced using eggs from paid donors. That rules out Mitalipovs lines, because his team paid egg donors US$3,0007,000 each, says Geoffrey Lomax, senior officer to the standards working group at CIRM, which is based in San Francisco. That amount is above and beyond any out-of-pocket costs to donors, he says.

The end result, says Mitalipov, is that a dozen or so universities are struggling to negotiate material transfer agreements to receive the new cell lines without running afoul of CIRM or the NIH. Interest in the new cell lines is high, especially since the identification of errors in images and figures in Mitalipovs research paper shortly after its publication in Cell. But regulations would require laboratories to use only dedicated, privately funded equipment to study the new cells, a condition that only a fewresearchers such as George Daley, a stem-cell expert at Boston Childrens Hospital in Massachusetts will be able to meet.

That concerns Daley, who calls the NIH stem-cell policy a frustrating limitation that will preclude federal dollars being used to ask many important questions about how Mitalipovs cell lines compare with induced pluripotent stem cells (iPS), which are created by reprograming adult cells to an embryonic state. Most labs will take the path of least resistance and continue working with iPS cells unless someone shows that there is a clear and compelling reason to change course, Daley says.

Mitalipov also worries that his cell lines wont be sufficiently analyzed, which he says could hamper efforts to understand how epigenetic changes modifications to chromosomes that determine how genes are expressed affect stem cells' ability to transform into a wide array of mature cell types. We just dont have that much expertise at looking at all aspects of epigenetics, he says.

But some scientists say that the impact of US stem-cell restrictions is overestimated. Alexander Meissner, a developmental biologist at the Harvard Stem Cell Institute in Cambridge, Massachusetts, says Mitalipov's cell lines will not reveal much about how stem cells transform. That work can be done only with eggs that are easy to come by, allowing scientists to examine the reprograming process at many points. In practical terms, that means relying on eggs from mice instead of humans. Everything is over by time you derive those cell lines, he says of Mitalipovs cells. There is no signature that would tell you what has happened. Its the wrong species.

In the meantime, CIRM is re-examining the rules that govern the research its supports. The institute is not likely to alter the restrictions against funding studies that pay cell donors, but it might overturn the rules against using cell lines produced in such studies, Lomax says. The original policy was set in 2006 to address concerns that arose in the wake of fraud and ethical violations by Woo Suk Hwang, then a researcher at Seoul National University.

Purification, culture and multi-lineage differentiation of zebrafish neural crest cells

Friday, February 28th, 2014

PUBLIC RELEASE DATE:

27-Feb-2014

Contact: Eric C. Liao cliao@partners.org Society for Experimental Biology and Medicine

Researchers at the Massachusetts General Hospital (MGH)/Harvard Medical School, Drs. Beste Kinikoglu and Yawei Kong, led by Dr. Eric C. Liao, cultured and characterized for the first time multipotent neural crest cells isolated from zebrafish embryos. This important study is reported in the February 2014 issue of Experimental Biology and Medicine. Neural crest is a unique cell population induced at the lateral border of the neural plate during embryogenesis and vertebrate development depends on these multipotent migratory cells. Defects in neural crest development result in a wide range of malformations, such as cleft lip and palate, and diseases, such as melanoma. Dr. Liao's laboratory uses zebrafish as a model vertebrate to study the genetic basis of neural crest related craniofacial malformations. Zebrafish has long been used to study early development and recently emerged as a model to study disease. "Development of in vitro culture of neural crest cells and reproducible functional assays will provide a valuable and complementary approach to the in vivo experiments in zebrafish" said Dr. Eric C. Liao, senior author of the study and an Assistant Professor of Surgery at MGH, and Principal Faculty at the Harvard Stem Cell Institute.

The team took advantage of the sox 10 reporter transgenic model to enrich and isolate the neural crest cells (NCCs), which were subsequently cultured under optimized culture conditions. Cultured NCCs were found to express major neural crest lineage markers such as sox10, sox9a, hnk1, p75, dlx2a, and pax3, and the pluripotency markers c-myc and klf4. The cells could be further differentiated into multiple neural crest lineages, contributing to neurons, glial cells, smooth muscle cells, melanocytes, and chondrocytes. Using the functional cell behavior assays that they developed, the team was able to assess the influence of retinoic acid, an endogenously synthesized, powerful, morphogenetic molecule, on NCC behavior. This study showed that retinoic acid had a profound effect on NCC morphology and differentiation, significantly inhibited proliferation and enhanced cell migration. The data implicate NCCs as a target cell population for retinoic acid and suggest that it plays multiple critical roles in NCC development.

"We hope that our novel neural crest system will be useful to gain mechanistic understanding of NCC development and for cell-based high-throughput drug screening applications" said Dr. Beste Kinikoglu, a postdoctoral fellow in Dr. Liao's laboratory and the study's first author. Dr. Steven R. Goodman, Editor-in-Chief of Experimental Biology and Medicine said "Liao and colleagues have provided the first zebrafish embryo derived NCC pure population in vitro model for the study of neural crest development. I believe that this will be a valuable tool for this purpose".

Skin cells transformed into functioning liver cells in mouse study

Monday, February 24th, 2014

The power of regenerative medicine now allows scientists to transform skin cells into cells that closely resemble heart cells, pancreas cells and even neurons. However, a method to generate cells that are fully mature -- a crucial prerequisite for life-saving therapies -- has proven far more difficult. But now, scientists at the Gladstone Institutes and the University of California, San Francisco (UCSF), have made an important breakthrough: they have discovered a way to transform skin cells into mature, fully functioning liver cells that flourish on their own, even after being transplanted into laboratory animals modified to mimic liver failure.

In previous studies on liver-cell reprogramming, scientists had difficulty getting stem cell-derived liver cells to survive once being transplanted into existing liver tissue. But the Gladstone-UCSF team figured out a way to solve this problem. Writing in the latest issue of the journal Nature, researchers in the laboratories of Gladstone Senior Investigator Sheng Ding, PhD, and UCSF Associate Professor Holger Willenbring, MD, PhD, reveal a new cellular reprogramming method that transforms human skin cells into liver cells that are virtually indistinguishable from the cells that make up native liver tissue.

These results offer new hope for the millions of people suffering from, or at risk of developing, liver failure -- an increasingly common condition that results in progressive and irreversible loss of liver function. At present, the only option is a costly liver transplant. So, scientists have long looked to stem cell technology as a potential alternative. But thus far they have come up largely empty-handed.

"Earlier studies tried to reprogram skin cells back into a pluripotent, stem cell-like state in order to then grow liver cells," explained Dr. Ding, one of the paper's senior authors, who is also a professor of pharmaceutical chemistry at UCSF, with which Gladstone is affiliated. "However, generating these so-called induced pluripotent stem cells, or iPS cells, and then transforming them into liver cells wasn't always resulting in complete transformation. So we thought that, rather than taking these skin cells all the way back to a pluripotent, stem cell-like state, perhaps we could take them to an intermediate phase."

This research, which was performed jointly at the Roddenberry Center for Stem Cell Research at Gladstone and the Broad Center of Regeneration Medicine and Stem Cell Research at UCSF, involved using a 'cocktail' of reprogramming genes and chemical compounds to transform human skin cells into cells that resembled the endoderm. Endoderm cells are cells that eventually mature into many of the body's major organs -- including the liver.

"Instead of taking the skin cells back to the beginning, we took them only part way, creating endoderm-like cells," added Gladstone and CIRM Postdoctoral Scholar Saiyong Zhu, PhD, one of the paper's lead authors. "This step allowed us to generate a large reservoir of cells that could more readily be coaxed into becoming liver cells."

Next, the researchers discovered a set of genes and compounds that can transform these cells into functioning liver cells. And after just a few weeks, the team began to notice a transformation.

"The cells began to take on the shape of liver cells, and even started to perform regular liver-cell functions," said UCSF Postdoctoral Scholar Milad Rezvani, MD, the paper's other lead author. "They weren't fully mature cells yet -- but they were on their way."

Now that the team was encouraged by these initial results in a dish, they wanted to see what would happen in an actual liver. So, they transplanted these early-stage liver cells into the livers of mice. Over a period of nine months, the team monitored cell function and growth by measuring levels of liver-specific proteins and genes.

Two months post-transplantation, the team noticed a boost in human liver protein levels in the mice, an indication that the transplanted cells were becoming mature, functional liver cells. Nine months later, cell growth had shown no signs of slowing down. These results indicate that the researchers have found the factors required to successfully regenerate liver tissue.
