StemCell Therapy

Mike Ivey writes on all matters money in the spirit of Capital Times founder William T. Evjue, who believed that the concentration of wealth in the U.S. is not healthy for the Democracy.

When UW-Madison's James Thomson in 1998 became the first scientist to grow human embryonic stem cells in a lab, it generated tremendous excitement about the medical possibilities.

Thomson tried to downplay the breakthrough but talk spread about cures for Alzheimers or Parkinsons disease, growing livers for cirrhosis suffers or producing healthy heart cells for cardiac patients.

The miracle cures have been slow in coming, however. Scientists can replicate healthy nerve cells in a Petri dish but havent found a way to replace defective spinal cells in ALS victims, for example.

In many ways, were still at the first steps,Anita Bhattacharyya, a senior scientist in the stem cell program at the UW's Waisman Center, told a business group Tuesday.

Butproducing stem cells for others to use is proving one of Madisons more promising new business ventures. Pharmaceutical companies in particular are using stem cells to test drugs before launching into expensive further testing.

Were making these cells available to the masses, says Chris Parker, chief technology officer at Cellular Dynamics International.

Launched by Thomson -- and backed with $100 million from a local investor group -- Cellular Dynamics International was lauded recently by MIT as one of the 50 most important companies in the world

Since its founding in 2005, the company now counts 107 employees at it offices in University Research Park and is continuing to grow.

Im hiring right now, Parker joked toa lunch crowd of the Wisconsin Technology Council Tuesday.

It was a mixed day on the market, as tech stocks lagged. Outside of tech, it was a nice bounce back for stocks, and we'd expect sentiment around Apple's (AAPL - News) strong earnings to help influence the market's mood tomorrow. In general, we're still looking for a spring/summer pullback, but continue to view it as a buying opportunity. Apple's pullback, though, may have already occurred, and once again it looks like the company is proving the skeptics wrong.

The Stem Cell Stocks Index was the top performing tickerspy Index on the day, led by BioTime (BTX - News) with a 14% gain. The Discount Retailer Stocks Index was the day's worst performing tickerspy Index, with Big Lots (BIG - News) down -24%.

Stocks finished mixed, with the Dow the lone loser off -9 points to 2,962. The Dow climbed 74 points to 13,002, while the Nasdaq rose 5 points to 1,372. Oil edged up 44 cents to $103.55 a barrel, while gold jumped $11.20 to $1,643.80 an ounce.

In economic news, the Conference Board said April's consumer confidence reading slid to 69.2 from a downwardly revised 69.5 in March. Economists had expected a reading of 69.7. Elsewhere, The S&P/Case-Shiller Home Price Index showed the 10- and 20-city measures both fell -0.8% month over month in February and slid -3.6% and -3.5%, respectively, year over year.

MARLBOROUGH, Mass.--(BUSINESS WIRE)--

Advanced Cell Technology, Inc. (ACT; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that the Data and Safety Monitoring Board (DSMB), an independent group of medical experts closely monitoring the Companys three ongoing clinical trials, have recently authorized the Company to move forward with enrollment and treatment of additional patients with Stargardts disease (SMD). In the U.S. SMD trial, ACT will screen and enroll patients for the second cohort, who, in keeping with trial protocol, will be injected with 100,000 retinal pigment epithelial (RPE) cells - as compared with the 50,000 cell dose used in the patients of the first cohort. The Company has also been approved to treat the final two patients to round out the initial dosing arm in its European trial. The use of pluripotent stem cells to derive RPE cells, and the use of the resulting RPE cells for treating a wide range of macular degenerative disorders, are covered by a robust patent portfolio owned by ACT, including a number of issued broad patents in key world markets.

DSMB authorization to move to the next higher dosage of cells in our U.S. clinical trial and complete the treatment of the first cohort of patient in our European trial represents yet another significant advancement for our clinical programs, commented Gary Rabin, chairman and CEO of ACT. We are pleased with the pace of progress and the continued finding of safety amongst the participants in both the U.S. and European trials. The results so far have been encouraging, and with our SMD programs having been granted orphan medicinal product designation in both the U.S. and Europe, we look forward to eventually reaching a stage at which we can further avail ourselves of all the regulatory and financial benefits this designation brings.

The three procedures comprising the first cohort of patients in the U.S. SMD trial were all conducted at University of California at Los Angeles (UCLA), by Steven Schwartz, M.D., Ahmanson Professor of Ophthalmology at the David Geffen School of Medicine at UCLA and retina division chief at UCLA's Jules Stein Eye Institute. The first procedure in the E.U. trial was conducted at Moorfields Eye Hospital in London, by a team of surgeons led by Professor James Bainbridge, consultant surgeon at Moorfields and Chair of Retinal Studies at University College London.

We are gratified to be moving to the next stage in both of our SMD trials, commented Robert Lanza, M.D., ACTs chief scientific officer. We remain very encouraged by the preliminary data in the first four SMD patients treated with the lowest dose of RPE cells at UCLA and Moorfields Eye Hospital. We are doubling the number of cells that will be transplanted in the next group of patients in the U.S. trial. We will be anxious to see if the higher dosage of RPE cells will impact visual function and photoreceptor rescue.

ACT is conducting three clinical trials in the U.S. and Europe using hESC-derived RPE cells to treat forms of macular degeneration. Each trial will enroll a total of 12 patients, with cohorts of three patients each in an ascending dosage format. These trials are prospective, open-label studies, designed to determine the safety and tolerability of hESC-derived RPE cells following sub-retinal transplantation into patients with dry-AMD or Stargardt's macular dystrophy (SMD) at 12 months, the studys primary endpoint. On January 20, 2012, the first SMD patient enrolled in the Companys U.K. clinical trial was treated at Moorfields Eye Hospital in London. The final patient of the first cohort in the companys SMD trial in the U.S. was treated on February 13, 2012.

Further information about patient eligibility for the dry AMD study and the concurrent study on SMD is also available on http://www.clinicaltrials.gov; ClinicalTrials.gov Identifiers: NCT01345006, NCT01469832 and NCT01344993.

PROGRAMMING HIGHLIGHTS: AMERICAN ASSOCIATION OF ANATOMISTS ANNUAL MEETING

Newswise The American Association of Anatomists will gather this week for its annual meeting in conjunction with the Experimental Biology 2012 conference, which will draw more than 14,000 scientists from industry, government and academia. Below are some programming highlights for the anatomy meeting. All presentations will be made at the San Diego Convention Center.

Stem cells derived from breast milk that behave like embryonic stem cells

Scientists in Australia have discovered that human breast milk contains stem cells that behave very much like embryonic stem cells. These breast-milk-derived, embryonic-like stem cells are able to turn into various body cell types, including bone, fat, liver, pancreatic and brain cells. Because breast milk is plentiful and can be accessed noninvasively and ethically, this discovery opens new avenues for exploration of innovative stem-cell therapies. Also, breast milk stem cells can be used as a physiological model to study malignant transformation that occurs in breast cancer, and therefore the findings may set the basis for research into new treatments for this disease. The group is now trying to understand the potential role of these breast milk cells for breastfed babies. (12:30 p.m.2 p.m. Tuesday, 4/24, poster in exhibit area)

The buzz about the exquisite little brains of big insects

A long tradition of studying invertebrates to learn about nervous systems has contributed greatly to our understanding of the functional organization, development and evolution of the intricate networks and the neural mechanisms that are at the root of behavior. Insects in particular offer powerful experimental model systems. Today, the most prominent example is the fruit fly, whose genetic and genomic advantages attract many researchers, but whose small size is limiting for some kinds of studies. This session focuses on much larger insects with beautiful and experimentally tractable nervous systems that permit investigations that complement and extend those accomplished with diminutive species. (10:30 a.m. 12:30 p.m. Monday, 4/23, Room 9)

From babies to bandages: reactivation of embryonic processes in adult injury repair

Embryonic tissue development and adult wound repair happen at different points in the life spectrum, but the molecules, cells and processes in that give rise to embryonic development are the same as those activated after injury. Only, the time it takes and the extent of the tissue-forming activities are quite different. Nonetheless, at this session, you might come to find that development and wound repair are just two sides of the same coin. (10:30 a.m. 12:30 p.m. Monday, 4/23, Room 7A)

Biology Major Adam Reese may have found the key to keep fat cells from forming.

The University of Delaware junior believes he has identified the trigger that turns a stem cell into a fat cell. Located on the surface of cells, the trigger, a protein called endoglin, regulates what type of cell an existing stem cell will become.

Working in the biological science department's laboratory of cellular signaling and dynamics with Assistant Professor Anja Nohe, Reese investigates ways to combat osteoporosis; his findings may also have implications for obesity.

Reese will present his work at 12:25 p.m. Monday at the American Society for Biochemistry and Molecular Biology's annual meeting, which is being held in San Diego in conjunction with the Experimental Biology 2012 conference.

Patients afflicted with osteoporosis lose bone mass as they age. Bone is a dynamic tissue, constantly renewed by removal or reabsorption of old bone and formation of new bone. Through this cellular remodeling process, roughly one fifth of an adult's skeleton is replaced each year. Of the limited treatments developed to reduce bone loss, most have potentially serious side effects, are cost prohibitive or difficult to use.

Reese, with the help of graduate student Joyita Dutta, found the amount of endoglin on a cell's surface indicates whether the cell will become a fat cell or a bone cell.

"What would happen if you could make the cell stop making the protein?" Reese said. "You could affect whether or not it's even a fat cell."

If the amount of endoglin on the cell surface could be decreased, the amount of cells turning into bone would rise, leading to an increase in bone strength, thus ending osteoporosis.

The fat stopper

From breast milk stem cells to bone repair, this years EB conference held a number of exciting advances that could one day be translated into therapies.

Milk stem cells

Australian scientists have found stem cells in breast milk that appear to behave much like embryonic stem cells. The cells differentiated into bone, fat, liver, pancreatic, and brain tissue. Because the cells can be easily collected, researchers hope they may provide a new source of cells for study and possibly future therapies. In addition, the researchers are investigating whether and how these cells are important for the health of breastfed babies.

Spurring bone regrowth

For years, scientists have been searching in vain for therapies that could help bone and cartilage heal and grow. But when researchers from the University of California, San Francisco, tried to regrow cartilage in damaged knees, the tissue instead turned to bone. While the result was unhelpful for their purposes, the researchers realized that cartilage might prove useful in rebuilding damaged bone, and are now exploring such applications.

A study by another group from Tulane University reported that high oxygen levels may help turn on the genetic program that initiates bone regrowth. When tissues samples taken from amputated limbs are exposed to about 20 percent oxygensignificantly more than the 6 percent typically found in the bodythe tissue responds favorably, said Tulanes Mimi Sammarco in a press releasebut only when administered at a certain point in time. The result wont be easily applied to clinical practice because blood vessels constrict after traumatic injury to prevent blood loss, reducing the amount of oxygen that reaches the damaged tissue even more. Thus, more work is needed to understand exactly when during the healing process high oxygen contributes to bone regrowth, and whether the same phenomenon occurs in the intact body.

More oxygen for chronic pain

More oxygen may also help relieve chronic pain. The application of pure oxygen, known as hyperbaric oxygen is used to treat an excruciatingly painful syndrome that divers experience called the bends, which results from the formation of nitrogen gas bubbles in the body as divers return to normal atmospheric pressure at the surface. Although the oxygen helps treat the symptoms, rather than the pain per se, researchers at Washington State University investigated whether the oxygen administration might also help relieve pain. Indeed, treated rats recovered more quickly from experimentally induced chronic pain. The researchers believe that the oxygen is likely to act on the brain to reduce pain, rather than by alleviating inflammation. Studying the mechanism could reveal molecular targets in the brain and possibly stimulate the development of new drugs that act on the same targets, lead author Raymond Quock of WSU said in a press release.

The University of Delaware junior believes he has identified the trigger that turns a stem cell into a fat cell. Located on the surface of cells, the trigger -- a protein called endoglin -- regulates what type of cell an existing stem cell will become.

If the amount of endoglin on the cell surface could be decreased, the amount of cells turning into bone would rise, leading to an increase in bone strength, thus ending osteoporosis.

"I didn't really expect it. I expected the data would be the other way around," said Nohe, Reese's undergraduate research adviser. "It's very exciting."

According to Nohe, researchers did not previously know if endoglin was the key controlling the cells' change or if it was just a marker. She believes Reese's data shows endoglin is the driver, and pinpointing that could lead to a cure.

"Now we have a target that we could hit," she said.

The fat stopper: Protein that regulates the creation of fat cells identified

Probably the simplest way to describe an artificial hip would be to say that its a ball attached to a stem. The stem is often fastened to the open end of the femur using a glass-like polymer known as bone cement, while the ball takes the place of the original hip bones ball joint, rotating within a corresponding implant in the socket of the pelvis. Although problems can occur at that ball-and-socket interface, they can also result when the bone cement cracks, causing the stem to detach from the femur. Scientists at MIT, however, have developed a new type of nanoscale film coating, designed to keep that from happening.

According to MIT, about 17 percent of patients who receive artificial hips will eventually require a total replacement of the implant due to loosening of the stem. That loosening typically causes patients to experience considerable discomfort, and a loss of mobility. When the existing implant is removed and a new one installed, tissue loss occurs, along with the various risks associated with surgery on the elderly the most common recipients of artificial hips.

The MIT film is intended as a substitute for bone cement. Applied at the stem/bone interface, the film ranges in width from 100 nanometers to one micron, and consists of layers of materials that encourage bone to grow from the femur into the implant. One of those materials is a natural component of bone, known as hydroxyapatite. It is composed of calcium and phosphate, and attracts stem cells from the adjacent bone marrow. Also incorporated into the film is a growth factor that causes those attracted stem cells to transform into osteoblasts, which are bone-producing cells.

Once the osteoblasts gets to work, the spaces between the implant and the existing bone are filled in with new bone. Although it takes at least two to three weeks for the implant to become thoroughly attached, patients should still be able to walk and perform physical therapy in the meantime. Not only should the new bone provide a more secure attachment than bone cement, but it should also make infections much less likely when bone cement is used, bacteria can collect within the gaps that remain between the existing bone and the implant.

Previous attempts have been made at coating implants with hydroxyapatite film, and at introducing growth factor, but they reportedly proved unsatisfactory. The films were thick, unstable and thus broke away from the implants, while it was difficult to keep the growth factor from draining away from the implant site. The MIT scientists, however, are able to precisely control the thickness of the film, and the rate at which it dispenses the growth factor.

So far, the film has been used in animal studies, where it has shown promising results. It is believed that it could be used not only for artificial hips, but also for other metal-in-bone applications such as dental implants, fixation plates, and screws used to set bone fractures.

A paper on the research was recently published in the journal Advanced Materials.

Nanocoating designed to keep hip implants where they belong

Newswise NEWARK, N.J. -- Sibling growth factors cooperate to maintain a pool of neuron-generating stem cells in the brain, according to a study published in the journal Stem Cells by researchers at the University of Medicine and Dentistry of New Jersey (UMDNJ).

Numerous soluble proteins and receptors help to maintain neural stem cells (NSCs) supportive environment in central nervous system (CNS). NSCs access some of these nurturing factors by sending cellular extensions into the cerebral spinal fluid (CSF), which is rich in stem cell-promoting proteins.

Insulin-like growth factors (IGF-I and IGF-II) are essential for the growth and development of the CNS. But although they are abundant in the brain and CSF, it was not clear whether they are required by NSCs. Steven Levison, PhD, and Teresa Wood, PhD, of UMDNJ-New Jersey Medical School and colleagues now show that IGF-I and II cooperate to maintain NSC numbers and the NSCs ability to self-renew. IGF-I maintains NSC numbers by promoting cell division (via the IGF-I receptor), whereas IGF-II drives the expression of proteins essential for NSC self-renewal and stemness (via the insulin receptor).

The role of IGF-I and -II in maintaining NSC numbers and function might help to explain the cognitive impairments associated with aging, as the abundance of both proteins declines with age.

Disclosure: This study was funded by a Deans grant from UMDNJ-New Jersey Medical School, NIH grants (R21HL094905, F31NS065607 and T32-HL069752) and a grant from the LeDucq Foundation.

The University of Medicine and Dentistry of New Jersey (UMDNJ) is New Jerseys only health sciences university with more than 6,000 students on five campuses attending the state's three medical schools, its only dental school, a graduate school of biomedical sciences, a school of health related professions, a school of nursing and New Jerseys only school of public health. UMDNJ operates University Hospital, a Level I Trauma Center in Newark, and University Behavioral HealthCare, which provides a continuum of healthcare services with multiple locations throughout the state.

ALAMEDA, Calif.--(BUSINESS WIRE)--

BioTime, Inc. (NYSE Amex: BTX) announced today that Charles S. Irving, Ph.D., the CEO of BioTimes subsidiary Cell Cure Neurosciences, Ltd. will provide an update on the development of OpRegen at an investor meeting in New York City. In his presentation, Dr. Irving will describe the unmet medical needs and markets for the treatment of the dry form of age-related macular degeneration (AMD), and the advantages of Cell Cures OpRegen which has been produced from human embryonic stem cells in culture conditions free of animal products, eliminating the need for designating the product as a xenotransplantation therapeutic. Dr. Irving will also discuss Cell Cures collaboration with Teva Pharmaceutical Industries Ltd., under which Teva has the option to develop and commercialize both OpRegen and OpRegen-Plus. Dr. Irving will describe the nature of the ongoing preclinical studies which are expected to lead to regulatory filings for the initiation of human clinical trials in 2013. Dr. Irvings presentation will be available on BioTimes web site http://www.biotimeinc.com as well as Cell Cure Neurosciences web site at http://www.cellcureneurosciences.com.

Background.

Age-related macular degeneration is the leading cause of blindness in an aging population. It is widely believed that the loss or dysfunction of a particular type of cell called retinal pigment epithelial (RPE) cells is the root cause of the disease. While therapies exist to treat what is called the wet form of macular degeneration exist, there are no therapies for the dry form. The transplantation of healthy RPE cells may provide a superior treatment for this devastating disorder. Cell Cures OpRegen is xeno-free, meaning that no animal products were used in the culture of the human embryonic stem cell-derived RPE cells. The use animal products to culture cells often results in the designation of the therapy as a xenotransplantation product, even though the cells themselves are of human origin. Xenotransplantation may raise purity issues, increasing the costs of product development along with other risks and uncertainties. The production of animal product-free OpRegen will therefore eliminate concerns of xenotransplantation and may provide cost savings in development and production should the product successfully complete clinical trials and be approved for human use.

Regenerative Medicine Institute, Mexico Presents Summary of Clinical Data at the International Society of Stem Cell ...

Just one week after the $3 billion California stem cell agency was sharply criticized for its failure to adequately support biotech firms, the agency formally kicked off a $30 million effort to engage industry more closely.

The initiative, in the works since the middle of last year, was heralded as the beginning of a "new era" for CIRM, which is moving to transform into cures the stem cell research it has funded over the last seven years. The agency has scheduled a webinar for April 25 for prospective applicants.

CIRM's press release, crafted by the agency's new PR/communications director, Kevin McCormack, yesterday quoted CIRM President Alan Trounson as saying,

"This initiative is a major new development in the progress towards providing new medical treatments for patients by engaging the most effective global industry partners."

Elona Baum, the agency's s general counsel and vice president of business development, said the program "represents a new era for CIRM."

Under the RFA, the agency will award up to $10 million each for three grants or loans. The program, however, is not limited to businesses. Non-profits may apply as well. Representatives from industry have complained about a strong tilt on the part of CIRM towards academic and non-profit research enterprises. The CIRM board is dominated by representatives from those two sectors.

The program grew out of recommendations in November 2010 from an "external review" panel put together by CIRM that said the agency needed to do better with business. The refrain was heard again directly from stem cell firms at last week's hearing by the Institute of Medicine on the stem cell agency's performance. According to CIRM's figures, businesses have received $54 million in grants and loans since 2005, the first year the CIRM board approved grants, out of a total of $1.3 billion.

Only one news outlet has written a story so far about the posting of the RFA and the press release, as far as can be determined.

Ron Leuty of the San Francisco Business Times said,

"The most likely candidates to attract industry funding would be CIRM’s 'disease team' grant winners, who face a deadline of 2014 to bring a project to the point of first-in-human clinical trials. CIRM has weighed options for pushing those projects — there are 13 of them now — deeper into the FDA approval process."

CIRM said in the RFA material,

"The intent of the initiative is to create incentives and processes that will: (i) enhance the likelihood that CIRM funded projects will obtain funding for Phase III clinical trials (e.g. follow-on financing), (ii) provide a source of co-funding in the earlier stages of clinical development, and (iii) enable CIRM funded projects to access expertise within pharmaceutical and large biotechnology partners in the areas of discovery, preclinical, regulatory, clinical trial design and manufacturing process development.

"This initiative requires applicants to show evidence of either having the financial capacity to move the project through development or of being able to attract the capital to do so. This may be evidenced by, for example, (i) significant investment by venture capital firms, large biotechnology or pharmaceutical companies and/or disease foundations; or (ii) a licensing and development agreement with a large biotechnology or pharmaceutical company or a commitment to enter into such an agreement executed prior to the disbursement of CIRM funding.

"The objective of the first call under this initiative, the Strategic Partnership I Awards, is to achieve, in 4 years or less, the completion of a clinical trial under an Investigational New Drug (IND) application filed with the Food and Drug Administration (FDA)."

CIRM has scheduled a webinar on the RFA for prospective applicants for next Wednesday, April 25. It is asking for registration and questions in advance.
