Reproducing Research Results: Removing a Scientific Roadblock

September 23rd, 2012 3:55 pm


The California stem cell agency faces
no easy task in trying to translate basic research findings into
something that can be used to treat patients and be sold commercially.

Even clinical trials, which only begin
long after the basic research is done and which involve more ordinary
therapeutic treatments than stem cells, fail at an astonishing rate.
Only one out of five that enter the clinical trial gauntlet
successfully finish the second stage, according to industry data
cited last spring by Pat Olson, executive director of scientific activities at the stem cell agency. And
then come even more challenges.
But at a much earlier stage of
research there is the “problem of irreproducible results,” in the
words of writer Monya Baker of the journal Nature. Baker last month reported on
moves by a firm called Science Exchange in Palo Alto, Ca., to
do something to ease the problem and speed up preclinical research.
The effort is called the Reproducibility Initiative and also involves
PLOS and figshare, an open science Internet project.

Science Exchange is headed by Elizabeth
Iorns
, a scientist and co-founder of the firm. She wrote about  test-tube-to-clinic translation issues in a recent article in New
Scientist
that was headlined, “Is medical science built on shaky
foundations?”
Iorns said,

“One goal of scientific publication
is to share results in enough detail to allow other research teams to
reproduce them and build on them. However, many recent reports have
raised the alarm that a shocking amount of the published literature
in fields ranging from cancer biology to psychology is not
reproducible.”

Iorns cited studies in Nature that
reported that Bayer cannot “replicate about two-thirds of published
studies identifying possible drug targets” and that Amgen failed at
even a higher rate. It could not “replicate 47 of 53 highly
promising results they examined.”
The California Stem Cell Report earlier
this week asked Iorns for her thoughts on the implications for the
California stem cell agency, whose motto is "Turning stem cells into cures." Here is the full text of her response.

“First, I think it is important to
accept that there is a crisis affecting preclinical research. Recent
studies estimate that 70% of preclinical research cannot be
reproduced. This is the research that should form the foundation upon
which new discoveries can be made to enhance health, lengthen life,
and reduce the burdens of illness and disability. The
irreproducibility of preclinical research is a significant impediment
to the achievement of these goals. To solve this problem requires
immediate and concrete action. It is not enough to make
recommendations and issue guidelines to researchers. Funders must act
to ensure they fund researchers to produce high quality reproducible
research. One such way to do so, is to reward, or require,
independent validation of results. The reproducibility initiative
provides a mechanism for independent validation, allowing the
identification of high quality reproducible research. It is vital
that funders act now to address this problem, to prevent the wasted
time and money that is currently spent funding non-reproducible
research and to prevent the erosion of public trust and support for
research.”

Solon urges Congress to conduct cursory check on the status of stem cell therapy in the country (15966897)

September 22nd, 2012 12:12 pm

According to Aristotle, only the Pentacosiomedimnoi were eligible for election to high office as archons and therefore only they gained admission into the Areopagus. A modern view affords the same privilege to the hippeis. The top three classes were eligible for a variety of lesser posts and only the Thetes were excluded from all public office.

Depending on how we interpret the historical facts known to us, Solon's constitutional reforms were either a radical anticipation of democratic government, or they merely provided a plutocratic flavour to a stubbornly aristocratic regime, or else the truth lies somewhere between these two extremes.

Solon's reforms can thus be seen to have taken place at a crucial period of economic transition, when a subsistence rural economy increasingly required the support of a nascent commercial sector. The specific economic reforms credited to Solon are these: Fathers were encouraged to find trades for their sons; if they did not, there would be no legal requirement for sons to maintain their fathers in old age. Foreign tradesmen were encouraged to settle in Athens; those who did would be granted citizenship, provided they brought their families with them. Cultivation of olives was encouraged; the export of all other produce was prohibited. Competitiveness of Athenian commerce was promoted through revision of weights and measures, possibly based on successful standards already in use elsewhere, such as Aegina or Euboia or, according to the ancient account but unsupported by modern scholarship, Argos

It is generally assumed, on the authority of ancient commentators that Solon also reformed the Athenian coinage. However, recent numismatic studies now lead to the conclusion that Athens probably had no coinage until around 560 BC, well after Solon's reforms.

Solon's economic reforms succeeded in stimulating foreign trade. Athenian black-figure pottery was exported in increasing quantities and good quality throughout the Aegean between 600 BC and 560 BC, a success story that coincided with a decline in trade in Corinthian pottery. The ban on the export of grain might be understood as a relief measure for the benefit of the poor. However, the encouragement of olive production for export could actually have led to increased hardship for many Athenians since it would have led to a reduction in the amount of land dedicated to grain. Moreover an olive produces no fruit for the first six years. The real motives behind Solon's economic reforms are therefore as questionable as his real motives for constitutional reform. Were the poor being forced to serve the needs of a changing economy, or was the economy being reformed to serve the needs of the poor?

Solon's reform of these injustices was later known and celebrated among Athenians as the Seisachtheia (shaking off of burdens). As with all his reforms, there is considerable scholarly debate about its real significance. Many scholars are content to accept the account given by the ancient sources, interpreting it as a cancellation of debts, while others interpret it as the abolition of a type of feudal relationship, and some prefer to explore new possibilities for interpretation. prohibition on a debtor's person being used as security for a loan. release of all Athenians who had been enslaved.

The removal of the horoi clearly provided immediate economic relief for the most oppressed group in Attica, and it also brought an immediate end to the enslavement of Athenians by their countrymen. Some Athenians had already been sold into slavery abroad and some had fled abroad to escape enslavement Solon proudly records in verse the return of this diaspora. It has been cynically observed, however, that few of these unfortunates were likely to have been recovered. It has been observed also that the seisachtheia not only removed slavery and accumulated debt, it also removed the ordinary farmer's only means of obtaining further credit.

The seisachtheia however was merely one set of reforms within a broader agenda of moral reformation. Other reforms included: the abolition of extravagant dowries. legislation against abuses within the system of inheritance, specifically with relation to the epikleros (i.e. a female who had no brothers to inherit her father's property and who was traditionally required to marry her nearest paternal relative in order to produce an heir to her father's estate). entitlement of any citizen to take legal action on behalf of another. the disenfranchisement of any citizen who might refuse to take up arms in times of civil strife, a measure that was intended to counteract dangerous levels of political apathy.

The personal modesty and frugality of the rich and powerful men of Athens in the city's subsequent golden age have been attested to by Demosthenes. Perhaps Solon, by both personal example and legislated reform, established a precedent for this decorum. A heroic sense of civic duty later united Athenians against the might of the Persians. Perhaps this public spirit was instilled in them by Solon and his reforms. Also see Solon and Athenian sexuality

The literary merit of Solon's verse is generally considered unexceptional. Solon the poet can be said to appear 'self-righteous' and 'pompous' at times and he once composed an elegy with moral advice for a more gifted elegiac poet, Mimnermus. Most of the extant verses show him writing in the role of a political activist determined to assert personal authority and leadership and they have been described by the German classicist Wilamowitz as a "versified harangue" (Eine Volksrede in Versen). According to Plutarch however, Solon originally wrote poetry for amusement, discussing pleasure in a popular rather than philosophical way. Solon's elegiac style is said to have been influenced by the example of Tyrtaeus. He also wrote iambic and trochaic verses which, according to one modern scholar, are more lively and direct than his elegies and possibly paved the way for the iambics of Athenian drama.

Einstein Hosts Its First Stem Cell Institute Symposium

September 22nd, 2012 7:18 am

Newswise September 21, 2012 (BRONX, NY) The promise of stem cells seems limitless. If they can be coaxed into rebuilding organs, repairing damaged spinal cords and restoring ravaged immune systems, these malleable cells would revolutionize medical treatment. But stem cell research is still in its infancy, as scientists seek to better understand the role of these cells in normal human development and disease.

On Friday, September 14, the Ruth L. and David S. Gottesman Institute for Stem Cell and Regenerative Medicine Research at Albert Einstein College of Medicine of Yeshiva University offered the Einstein community and invited guests an opportunity to hear from leading stem cell scientists investigating the dynamic field. The 2012 Einstein Stem Cell Institute Symposium featured speakers from around the globe presenting the latest research on induced pluripotent stem cells (iPS cells), cell reprogramming, as well as cancer and hematopoietic (blood-forming) stem cells.

This symposium was an important milestone for stem cell research at Einstein and confirms our intent to contribute to advances in stem cell biology, said the events host and organizer, Paul Frenette, M.D., director and chair of Einsteins Stem Cell Institute and professor of medicine and of cell biology.

There has been a lot of hype in the past few years about the promise of stem cell research and some concerns that perhaps it was oversold to the public, said Dr. Frenette. The symposiums speakers nicely illustrated the tremendous progress that has been made thus far and showed how outstanding research is helping us to realize the full potential of stem cells.

The afternoon event included four presentations: George Q. Daley, M.D., Ph.D., discussed Lin28 in Stem Cells and Disease. Dr. Daley is the Samuel E. Lux IV Professor of Hematology/Oncology and director of the Stem Cell Transplantation Program at Boston Childrens Hospital; professor of biological chemistry and molecular pharmacology, of medicine, and of pediatrics at Harvard Medical School; and an investigator of the Howard Hughes Medical Institute.

Kathrin Plath, Ph.D., gave a talk on the Mechanisms of Reprogramming of Pluripotency. Dr. Plath is associate professor of biological chemistry at the University of California, Los Angeless David Geffen School of Medicine.

Toshio Suda, M.D., Ph.D., professor of cell differentiation at the Graduate School of Medicine, Keio University in Tokyo, Japan, presented Hematopoietic Stem Cells in Hypoxic Niches.

Andreas Trumpp, Ph.D., professor and head of the division of stem cells and cancer, and managing director of the Heidelberg Institute for Stem Cell Technology and Experimental Medicine in Heidleberg, Germany, discussed Circulating Metastasis-initiating Cells in Breast Cancer.

Dr. Frenette closed the event by thanking the speakers and the 100 attendees in the Ethel and Samuel J. LeFrak Auditorium, as well as additional attendees viewing the proceedings from overflow rooms in Einsteins Michael F. Price Center for Genetic and Translational Medicine/Harold and Muriel Block Research Pavilion.

We hope this symposium will foster collaborations between Einstein faculty members and leaders in the field, and embolden our developing program toward new heights of research excellence, said Dr. Frenette.

Research suggests promise of cell therapy for bowel disease

September 20th, 2012 8:15 am

Public release date: 19-Sep-2012 [ | E-mail | Share ]

WINSTON-SALEM, N.C. Sept. 19, 2012 New research shows that a special population of stem cells found in cord blood has the innate ability to migrate to the intestine and contribute to the cell population there, suggesting the cells' potential to treat inflammatory bowel disease (IBD).

"These cells are involved in the formation of blood vessels and may prove to be a tool for improving the vessel abnormalities found in IBD," said lead author Graca Almeida-Porada, M.D., Ph.D., a professor at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine. The research is published in the current print issue of the journal Hepatology.

Up to 1 million Americans have IBD, which is characterized by frequent diarrhea and abdominal pain. IBD actually refers to two conditions ulcerative colitis and Crohn's disease in which the intestines become red and swollen and develop ulcers. With IBD, blood vessels in the intestine leak and contribute to inflammation.

While there is currently no cure for IBD, there are drug therapies aimed at reducing inflammation and preventing the immune response. However, these therapies aren't always effective. The long-term aim of the research is to develop an injectable cell therapy to induce tissue recovery.

The work, performed while Almeida-Porada was at the University of Nevada, also involved colleagues from Indiana University School of Medicine. The researchers studied a special population of cells, known as endothelial colony-forming cells, found in cord blood, bone marrow and circulating blood. The finding in 1997 that the cells can contribute to blood vessel formation in adults, not just embryos, initiated the notion of using them for therapy. Studies in humans have validated the ability of these cells to improve reduced blood flow to the limbs and to treat heart diseases.

However, there have been few studies to explore the inherent biologic ability of these cells to home to different organs and contribute to tissue-specific cell populations. Evaluating their potential to migrate to the intestine was an obvious choice, said Almeida-Porada, because dysfunctional blood vessels are a hallmark of IBD. Not only are circulating levels of vessel-forming cells reduced in patients with IBD, but a key factor in IBD progression is the development of abnormal or immature blood vessels, which leads to chronic inflammation.

The cells were injected into fetal sheep at 59 to 65 days gestation. About 11 weeks later, intestinal tissue was analyzed to detect the presence of the human cells. The researchers found that the human cells had migrated to the intestine and contributed significantly to the cell population there.

"This study shows that the cells can migrate to and survive in a healthy intestine and have the potential to support vascular health," said Almeida-Porada. "Our next step will be to determine whether the cells can survive in the 'war' environment of an inflamed intestine."

Promise of cell therapy for bowel disease

September 20th, 2012 8:14 am

ScienceDaily (Sep. 19, 2012) New research shows that a special population of stem cells found in cord blood has the innate ability to migrate to the intestine and contribute to the cell population there, suggesting the cells' potential to treat inflammatory bowel disease (IBD).

The research was supported by the National Heart, Lung, and Blood Institute grants HL097623 and HL073737.

Discovery of reprogramming signature may help further stem cell-based regenerative medicine research

September 19th, 2012 3:20 pm

Public release date: 18-Sep-2012 [ | E-mail | Share ]

Contact: Andy Hoang ahoang@salk.edu 619-861-5811 Salk Institute

LA JOLLA, CA---- Salk scientists have identified a unique molecular signature in induced pluripotent stem cells (iPSCs), "reprogrammed" cells that show great promise in regenerative medicine thanks to their ability to generate a range of body tissues.

In this week's Proceedings of the National Academy of Sciences, the Salk scientists and their collaborators at University of California, San Diego, report that there is a consistent, signature difference between embryonic and induced pluripotent stem cells. The findings could help overcome hurdles to using the induced stem cells in regenerative medicine.

"We believe that iPSCs hold a great potential for the treatment of human patients," says Juan Carlos Izpisua Belmonte, a professor in Salk's Gene Expression Laboratory and the senior author on the paper. "Yet we must thoroughly understand the molecular mechanisms governing their safety profile in order to be confident of their function in the human body. With the discovery of these small, yet apparent, epigenetic differences, we believe that we are now one step closer to that goal."

Embryonic stem cells (ESCs) are known for their "pluripotency," the ability to differentiate into nearly any cell in the body. Because of this ability, it has long been thought that ESCs would be ideal to customize for therapeutic uses. However, when ESCs mature into specific cell types, and are then transplanted into a patient, they may elicit immune responses, potentially causing the patient to reject the cells.

In 2006, scientists discovered how to revert mature cells, which had already differentiated into particular cell types, such as skin cells or hair cells, back into a pluripotent state. These "induced pluripotent stem cells" (iPSCs), which could be developed from the patient's own cells, would theoretically carry no risk of immune rejection.

However, scientists found that iPSCs had molecular differences from embryonic stem cells. Specifically, there were epigenetic changes, chemical modifications in DNA that might alter genetic activity. At certain points in the iPSC's genome, scientists could see the presence of different patterns of methyl groups when compared to the genomes of ESCs. It seemed these changes occurred randomly.

Izpisua Belmonte and his colleagues wanted to understand more about these differences. Were they truly random, or was there a discernable pattern?

Unlike previous studies, which had primarily analyzed iPSCs derived from only one mature type of cells (mainly connective tissue cells called fibroblasts), the Salk and UCSD researchers examined iPSCs derived from six different mature cell types to see if there were any commonalities. They discovered that while there were hundreds of unpredictable changes, there were some that remained consistent across the cell types: the same nine genes were associated with these common changes in all iPSCs.

Discovery of reprogramming signature may help overcome barriers to stem cell-based regenerative medicine

September 19th, 2012 4:12 am

ScienceDaily (Sep. 18, 2012) Salk scientists have identified a unique molecular signature in induced pluripotent stem cells (iPSCs), "reprogrammed" cells that show great promise in regenerative medicine thanks to their ability to generate a range of body tissues.

In this week's Proceedings of the National Academy of Sciences, the Salk scientists and their collaborators at University of California, San Diego, report that there is a consistent, signature difference between embryonic and induced pluripotent stem cells. The findings could help overcome hurdles to using the induced stem cells in regenerative medicine.

"We believe that iPSCs hold a great potential for the treatment of human patients," says Juan Carlos Izpisua Belmonte, a professor in Salk's Gene Expression Laboratory and the senior author on the paper. "Yet we must thoroughly understand the molecular mechanisms governing their safety profile in order to be confident of their function in the human body. With the discovery of these small, yet apparent, epigenetic differences, we believe that we are now one step closer to that goal."

Embryonic stem cells (ESCs) are known for their "pluripotency," the ability to differentiate into nearly any cell in the body. Because of this ability, it has long been thought that ESCs would be ideal to customize for therapeutic uses. However, when ESCs mature into specific cell types, and are then transplanted into a patient, they may elicit immune responses, potentially causing the patient to reject the cells.

In 2006, scientists discovered how to revert mature cells, which had already differentiated into particular cell types, such as skin cells or hair cells, back into a pluripotent state. These "induced pluripotent stem cells" (iPSCs), which could be developed from the patient's own cells, would theoretically carry no risk of immune rejection.

However, scientists found that iPSCs had molecular differences from embryonic stem cells. Specifically, there were epigenetic changes, chemical modifications in DNA that might alter genetic activity. At certain points in the iPSC's genome, scientists could see the presence of different patterns of methyl groups when compared to the genomes of ESCs. It seemed these changes occurred randomly.

Izpisua Belmonte and his colleagues wanted to understand more about these differences. Were they truly random, or was there a discernable pattern?

Unlike previous studies, which had primarily analyzed iPSCs derived from only one mature type of cells (mainly connective tissue cells called fibroblasts), the Salk and UCSD researchers examined iPSCs derived from six different mature cell types to see if there were any commonalities. They discovered that while there were hundreds of unpredictable changes, there were some that remained consistent across the cell types: the same nine genes were associated with these common changes in all iPSCs.

"We knew there were differences between iPSCs and ESCs," says Sergio Ruiz, first author of the paper, "We now have an identifying mark for what they are."

The therapeutic significance of these nine genes awaits further research. The importance of the current study is that it gives stem cells researchers a new and more precise understanding of iPSCs.

America Stem Cell, Inc. Awarded a Phase I STTR to Explore the Therapeutic Potential of Its Platform Technology (ASC …

September 17th, 2012 7:12 pm

SAN ANTONIO--(BUSINESS WIRE)--America Stem Cell, Inc. (ASC) today announced that it has been awarded an Advanced Technology Small Business Technology Transfer Research (STTR) grant from the National Heart Lung and Blood Institute at the National Institutes of Health. This grant will be conducted in collaboration with scientists at the Wake Forest Institute of Regenerative Medicine (WFIRM) in Winston-Salem, NC, and will explore the combination of two technologies: ASC-101 developed by America Stem Cell and amniotic fluid-derived stem cells discovered and pioneered by Dr. Shay Soker and colleagues at WFIRM. We will examine the effect of ASC-101-treated amniotic fluid-derived stem cells in an experimental model of compartment syndrome. Compartment syndrome results from a variety of injuries such as fractures, contusions, burns, trauma, post-ischemic swelling and blast injuries such as gunshot wounds. If not addressed quickly, it can lead to considerable loss of muscle tissue. Musculoskeletal disorders are the primary cause of disability in the United States with associated costs of more than $800 billion annually. In addition to civilian injuries, more than 42,000 soldiers have been injured since the beginning of the Iraq and Afghanistan wars: the majority of these injuries were musculoskeletal in nature.

The successful combination of ASC-101 with amniotic fluid-derived stem cells would be directly relevant to improving the treatment of muscle damage that occurs following compartment syndrome as well as multiple other types of injuries.

America Stem Cell has demonstrated that ASC-101 enhances the ability of stem cells to migrate to their target tissue. While most companies are concerned with the type of cells used for cell therapy (i.e. the hardware), America Stem Cell addresses how to get the cells to go where they are needed most (i.e. the software). With this award, America Stem Cell will expand the potential for therapeutic application of ASC-101 with amniotic fluid-derived stem cells. According to Dr. Leonard Miller, the Co-Principal Investigator on the grant, The successful combination of ASC-101 with amniotic fluid-derived stem cells would be directly relevant to improving the treatment of muscle damage that occurs following compartment syndrome as well as multiple other types of injuries.

America Stem Cell, Inc. is a clinical stage company that is in clinical trials at the University of Texas M.D. Anderson Cancer Center for improving clinical outcomes for cancer patients undergoing hematopoietic stem cell transplantation. This award enables America Stem Cell to expand the development of ASC-101 to yet another cell type. Lynnet Koh, CEO of America Stem Cell, noted, The combination of ASC-101 with amniotic fluid-derived stem cells could synergistically enhance the therapeutic and regenerative capacity of these cells and most importantly provide an off-the-shelf, effective solution for tissue damage due to multiple types of injuries or diseases. ASC-101 is a transformative technology with the potential to improve clinical outcomes for patients undergoing a wide variety of cell therapies for the treatment of diseases such as graft versus host disease, diabetic complications, and ischemic diseases such as myocardial infarctions, retinopathy and critical limb ischemia. America Stem Cell has established a number of collaborations examining the potential of ASC-101 to improve cell therapies for multiple clinical conditions using a wide variety of cell types.

About America Stem Cell, Inc.

America Stem Cell is a privately held biotechnology company based in San Antonio, TX, with offices in San Diego, CA, and is dedicated to the development and commercialization of enabling technologies to enhance and expand the therapeutic potential of cell therapies. The key technology platforms (ASC-101 and ASC-102) are designed to improve the homing and engraftment of cells to target organs. ASC-101 is currently in clinical trials to improve the therapeutic potential of hematopoietic stem cells for patients in need of hematopoietic stem cell transplantation. Additionally, these technologies have the potential to enhance the efficacy of cell therapies for the treatment of inflammation from chemotherapy/radiation, autoimmune diseases, and ischemic diseases including myocardial infarction and stroke. America Stem Cell has partnerships and collaborations with Kyowa Hakko Kirin, Spectrum Medical Innvoations, Florida Biologix, and various medical research institutions including the University of Texas M.D. Anderson Cancer Center, Oklahoma Medical Research Foundation, Fred Hutchinson Cancer Center,,University of California San Diego, Sanford-Burnham Institute, Indiana University, Juvenile Diabetes Research Foundation, as well as corporate partnerships.

At the Right Place at the Right Time – New Insights into Muscle Stem Cells

September 17th, 2012 7:12 pm

17.09.2012 - (idw) Max-Delbrck-Centrum fr Molekulare Medizin (MDC) Berlin-Buch

Muscles have a pool of stem cells which provides a source for muscle growth and for regeneration of injured muscles. The stem cells must reside in special niches of the muscle for efficient growth and repair. The developmental biologists Dr. Dominique Brhl and Prof. Carmen Birchmeier of the Max Delbrck Center for Molecular Medicine (MDC) Berlin-Buch have elucidated how these stem cells colonize these niches. At the same time, they show that the stem cells weaken when, due to a mutation, they locate outside of the muscle fibers instead of in their stem cell niches (Developmental Cell, http://dx.doi.org/10.1016/j.devcel.2012.07.014)*. Muscle stem cells, also called satellite cells, colonize a niche that is located between the plasma membrane of the muscle cell and the surrounding basal lamina. Already in newborns these niches contain satellite cells from which both muscle cells and new stem cells can be generated.

Weakened stem cells In the present study Dr. Brhl and Professor Birchmeier showed that mouse muscle progenitor cells lacking components of the Notch signaling pathway cannot colonize their niche. Instead the muscle progenitor cells locate in tissue between the muscle fibers. The developmental biologists view this as the cause for the weakening of the muscles. The stem cells that are in the wrong place are no longer as potent as they originally were and hardly contribute to muscle growth.

In addition, the Notch signaling pathway has a second function in muscle development. It prevents the differentiation of stem cells into muscle cells through suppression of the muscle developmental factor MyoD and thus ensures that there will always be a pool of stem cells for muscle repair and regeneration. In the future this work could gain in importance for research on muscle regeneration and muscle weakness.

Upstate Medical breaking ground today on $15 million cord blood bank

September 17th, 2012 7:12 pm

Syracuse, N.Y. -- Luca Vassallo went through five rounds of chemotherapy, localized radiation and multiple surgeries to deal with the aftermath of his cancer treatment, all before he turned 1 year old.

In the end, the procedure that sent him into remission involved an intravenous drip and a strangers donated blood cells.

Its like a transfusion, said Lucas mother, Manal Vassallo, of Camillus, explaining how donated blood from a strangers umbilical cord filled her boys body with healthy cells.

They take a vial and hook it up through the IV and drip the cord blood in, Vassallo said. It was a really peaceful day.

Blood transplants like the one that helped Luca could become much more prevalent throughout New York. Today, Upstate Medical University will break ground on a $15 million, state-owned public cord blood bank, the second of its kind in New York.

The long-delayed Upstate Cord Blood Bank, at the former Community General campus in Onondaga, will store blood donations collected from umbilical cords and placentas, which most often are thrown out after deliveries.

Those materials contain stem cells, building blocks of the immune system that generate new blood and can even change a recipients blood type. Cord blood stem cells are used in the treatment of more than 60 malignant, genetic and acquired blood diseases such as leukemia, lymphoma and sickle cell anemia.

Through the donations of cord blood from families all across our region, we have the ability to save lives through transplantation and further fuel biomedical research that may move us closer in finding breakthroughs for dozens of diseases, said Dr. David Smith, president of Upstate.

The facility is part of a nationwide push to grow cord blood collections and solicit more donations from women of different races and ethnicities to increase the chance for successful transplants.

We want to develop in this country an inventory so that anyone who qualifies, by their disease, could have this available, said Tom Quinn, the senior vice president for health system development at Upstate. Right now, (the pool is) not as genetically diverse as it ought to be.
