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.

Sp2 protein plays a key role in creation of neurons from stem cells

A protein known as Sp2 is key to the proper creation of neurons from stem cells, according to researchers at North Carolina State University. Understanding how this protein works could enable scientists to "program" stem cells for regeneration, which has implications for neural therapies.

Stem cell transplantation prevents decrease in heart function associated with DMD

Researchers have shown that transplanting stem cells derived from normal mouse blood vessels into the hearts of mice that model the pathology associated with Duchenne muscular dystrophy (DMD) prevents the decrease in heart function associated with DMD.

Knee cartilage repair success with new biomaterial

In a small study, researchers reported increased healthy tissue growth after surgical repair of damaged cartilage if they put a “hydrogel” scaffolding into the wound to support and nourish the healing process. The squishy hydrogel material was implanted in 15 patients during standard microfracture surgery, in which tiny holes are punched in a bone near the injured cartilage. The holes stimulate patients’ own specialized stem cells to emerge from bone marrow and grow new cartilage atop the bone.

New hope for people with sound-induced deafness

Preliminary results from a study in mice suggest it may be possible to regenerate cochlear hair cells that have been damaged due to excessive noise exposure.

Repression of PTB protein in fibroblasts can convert pluripotent stem cells into functional neurons

Repression of a single protein in ordinary fibroblasts is sufficient to directly convert the cells - abundantly found in connective tissues - into functional neurons. The findings, which could have far-reaching implications for the development of new treatments for neurodegenerative diseases like Huntington's, Parkinson's and Alzheimer's, will be published online in advance of the January 17 issue of the journal Cell.

Baboon embryonic stem cells can be programmed to completely restore severely damaged arteries

Scientists at the Texas Biomedical Research Institute have for the first time demonstrated that baboon embryonic stem cells can be programmed to completely restore a severely damaged artery. These early results show promise for eventually developing stem cell therapies to restore human tissues or organs damaged by age or disease.

Apparent stem cell transplant success in mice may hold promise for people with ALS

Apparent stem cell transplant success in mice may hold promise for people with amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease.

SLU researchers to test new screening method for MPS disorders among infants

Researchers at Saint Louis University have received a five-year, $2.5 million National Institutes of Health grant to test a new method of screening newborns for a group of rare, but serious genetic disorders that affect approximately 200 babies born in the U.S., each year.

Clinical trials aim to repair bones using adult stem cells combined with biomaterials

The clinical trials aim to repair bones using adult stem cells combined with biomaterials. It will be conducted in France in the Cr-teil University Hospital Centre and the Regional University Hospital Centre in Tours, in collaboration with the French Blood Establishment.

High court turns away challenge to Obama administration stem cell policy

Meanwhile, the Supreme Court heard arguments in a case involving Medicaid and malpractice awards. In addition, the justices rejected an appeal from Social Security recipients who don't want Medicare benefits.

Researchers develop new materials to support stem cell growth

Stem cell manufacturing for drug screening and treatments for diseases such as Huntington's and Parkinson's could be boosted by a new method of generating stem cells, a study suggests.

Key link between stem cell factors that fuel ovarian cancer's growth and patient prognosis

Researchers at Yale School of Medicine have identified a key link between stem cell factors that fuel ovarian cancer's growth and patient prognosis. The study, which paves the way for developing novel targeted ovarian cancer therapies, is published online in the current issue of Cell Cycle.

Researchers show that protein p62 balances metabolism in fat tissue

In many cases, obesity is caused by more than just overeating and a lack of exercise. Something in the body goes haywire, causing it to store more fat and burn less energy. But what is it? Researchers at Sanford-Burnham Medical Research Institute have a new theory-a protein called p62.

Manipulating T cells with iPSC techniques could help develop effective immune therapies

The human body contains immune cells programmed to fight cancer and viral infections, but they often have short lifespans and are not numerous enough to overcome attacks by particularly aggressive malignancies or invasions.

Researchers create killer T lymphocytes from iPS cells

Researchers from the RIKEN Research Centre for Allergy and Immunology in Japan report today that they have succeeded for the first time in creating cancer-specific, immune system cells called killer T lymphocytes, from induced pluripotent stem cells (iPS cells).

Stanford scientists identify molecular basis for hypertrophic cardiomyopathy

When a young athlete dies unexpectedly on the basketball court or the football field, it's both shocking and tragic. Now Stanford University School of Medicine researchers have, for the first time, identified the molecular basis for a condition called hypertrophic cardiomyopathy that is the most common cause for this type of sudden cardiac death.

PSCA gene’s rs2294008 variant on T nucleotide may increase risk of bladder cancer

Patients who have inherited a specific common genetic variant develop bladder cancer tumors that strongly express a protein known as prostate stem cell antigen (PSCA), which is also expressed in many pancreatic and prostate tumors, according to research at the National Institutes of Health.
