Stem Cells News and Research

RSS

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

U.K. Human Fertilisation and Embryology Authority approves compensation for eggs donated for research

The United Kingdom's Human Fertilisation and Embryology Authority on Wednesday approved a policy that will allow women who donate eggs for human embryonic stem cell research to receive up to $500 for each cycle to cover costs associated with travel and lost wages, the AP/Washington Post reports

Research defines the cancer role for protein Gab-2

A protein known for its ability to "bridge" interactions between other cellular proteins may spur metastasis in breast cancer, the disease's deadliest stage, a study from Burnham Institute for Medical Research has found.

How stem cells are regulated

Researchers from Biotech Research & Innovation Centre (BRIC) at University of Copenhagen have identified a new group of proteins that regulate the function of stem cells. The results are published in the new issue of Cell.

First embryonic stem cell research grants approved under California Proposition 71

The California Institute for Regenerative Medicine's Independent Citizens' Oversight Committee on Friday announced the approval of the first human embryonic stem cell research grants provided under Proposition 71, the San Francisco Chronicle reports.

Increased demand, compensation for egg donors in U.S.

The AP/Boston Globe on Monday examined how increased demand for egg donations and compensation for donors in the U.S. has prompted more young women to donate their eggs. According CDC data, about 10,000 women donated eggs to federally monitored programs in 2004, compared with 3,800 women in 1996.

Women in the UK to trade eggs for IVF treatment

According to the fertility regulator in the UK women there will soon be able to donate their eggs for medical research.

Pregnancy hormone prolactin gives hope to MS victims

Canadian scientists believe they may be some way to solving the mystery of why women suffering from multiple sclerosis (MS) go into remission while they are pregnant.

Cell-based bone tissue engineering

In an article in PLoS Medicine, Gert Meijer (University Medical Centre Utrecht, The Netherlands) and colleagues discuss what kind of progress there has been in restoring the function of diseased or damaged bone by bone tissue regeneration.

California Appellate Court panel hears arguments in challenge of State proposition promoting embryonic stem cell research

A three-judge panel of the California Court of Appeal in San Francisco on Wednesday heard oral arguments in two consolidated cases challenging the constitutionality of California's Proposition 71 -- approved by voters in 2004 to provide $3 billion for human embryonic stem cell research -- the Los Angeles Times reports.

Cancer is a stem cell issue

There is an urgent reason to study stem cells: stem cells are at the heart of some, if not all, cancers. Mounting evidence implicates a clutch of rogue stem cells brandishing 'epigenetic' marks as the main culprits in cancer. Wiping out tumours for good, some biologists believe, depends on uprooting these wayward stem cells.

Epigenetics to shape stem cell future

Everyone hopes that one day stem cell-based regenerative medicine will help repair diseased tissue. Before then, it may be necessary to decipher the epigenetic signals that give stem cells their unique ability to self-renew and transform them into different cell types.

Kaiser Permanente launches long term project to collect genetic data

California-based HMO Kaiser Permanente on Wednesday announced the creation of a decades-long research project that will collect and analyze genetic information from hundreds of thousands of adult members, the San Jose Mercury News reports.

Researchers replace organ in mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice.

Women who donate eggs for stem cell research face few health risks

Women who donate their eggs for stem cell research or in vitro fertilization are not at increased risk of health complications, and most of the risks are a result of the hormones used to stimulate their bodies to release more than one egg, according to a report commissioned by the California Institute of Regenerative Medicine and released by the Institute of Medicine, Bloomberg reports.

New approach to nerve repair with novel silk-based products

A new company, Neurotex Ltd, has been established to develop novel silk-based products that have the potential to provide a new generation of nerve repair materials and treatments.

Rate of stem cell transplants among African-Americans lower

Lower transplant rates in ethnic communities may be explained somewhat by a lack of suitable anonymous donors, a problem the medical community has long known and been working to address. Surprisingly, the study found the discrepancy in treatment held true even when the transplant was autologous (e.g. self-donated stem cells were used) or when the cells were donated by a relative, typically a sibling.

Scientists discover master switches for adult blood stem cells

Johns Hopkins Kimmel Cancer Center scientists have found a set of "master switches" that keep adult blood-forming stem cells in their primitive state.

ViroPharma receives orphan drug designation for Maribavir

ViroPharma Incorporated today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation for maribavir for prevention of cytomegalovirus (CMV) viremia and disease in the populations at-risk.

Three-dimensional fabric "scaffold" to repair cartilage damage

Using a unique weaving machine of their design, Duke University Medical Center researchers have created a three-dimensional fabric "scaffold" that could greatly improve the ability of physicians to repair damaged joints with the patient's own stem cells.
