Findings uncover epigenomic modification that occurs during brain formation

Changes in the epigenome, including chemical modifications of DNA, can act as an extra layer of information in the genome, and are thought to play a role in learning and memory, as well as in age-related cognitive decline.

Researchers identify role of Nanog gene in embryonic stem cell differentiation

Whitehead Institute researchers have determined that the transcription factor Nanog, which plays a critical role in the self-renewal of embryonic stem cells, is expressed in a manner similar to other pluripotency markers.

Scientists discover network for molecular communication in human embryonic stem cells

Scientists at A*STAR's Genome Institute of Singapore (GIS) and the Max Planck Institute for Molecular Genetics (MPIMG) in Berlin (Germany) have discovered a molecular network in human embryonic stem cells (hESCs) that integrates cell communication signals to keep the cell in its stem cell state.

UCSF researchers find that vitamin C may help stem cells, in vitro fertilization

Vitamin C affects whether genes are switched on or off inside mouse stem cells, and may thereby play a previously unknown and fundamental role in helping to guide normal development in mice, humans and other animals, a scientific team led by UC San Francisco researchers has discovered.

Study: Pluripotent stem cell line-derived neurons survive and respond to cues in the primate brain

A team of researchers from Rush University, Yale University, the University of Colorado and the St. Kitts Biomedical Research Foundation transplanted human embryonic stem cells into primate laboratory animals modeled with Parkinson's disease and found "robust survival" of the cells after six weeks and indications that the cells were "well integrated" into the host animals.

Researchers identify biochemical pathway essential for promoting head and neck cancer

A study led by researchers at The Ohio State University Comprehensive Cancer Center-- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute has identified a biochemical pathway in cancer stem cells that is essential for promoting head and neck cancer.

Targeting SALL4 protein with druglike molecules could halt tumor growth, say researchers

Harvard Stem Cell Institute researchers have identified in the most aggressive forms of cancer a gene known to regulate embryonic stem cell self-renewal, beginning a creative search for a drug that can block its activity.

Researchers use patient-specific stem cells to correct deficient insulin-producing cells

A team from the New York Stem Cell Foundation Research Institute and the Naomi Berrie Diabetes Center of Columbia University has generated patient-specific beta cells, or insulin-producing cells, that accurately reflect the features of maturity-onset diabetes of the young.

Mount Sinai researchers produce cells that resemble hematopoietic stem cells

By transferring four genes into mouse fibroblast cells, researchers at the Icahn School of Medicine at Mount Sinai have produced cells that resemble hematopoietic stem cells, which produce millions of new blood cells in the human body every day.

Research discovery could shed light on unsolved cases of arrhythmia

The heart's regular rhythm is crucial to the delivery of oxygenated blood and nutrients to all the organs of the body. It is regulated by a bundle of cells called "the pacemaker," which use electrical signals to set the pace of the heart. Dysfunction in this mechanism can lead to an irregular heartbeat, known as arrhythmia, and often necessitates the implantation of an artificial pacemaker.

Liver regeneration using cell therapy may be possible, study suggests

Liver transplantation is the mainstay of treatment for patients with end-stage liver disease, the 12th leading cause of death in the United States, but new research from the Icahn School of Medicine at Mount Sinai, published in the online journal Cell Stem Cell today, suggests that it may one day become possible to regenerate a liver using cell therapy in patients with liver disease.

Rewinding the developmental state of embryonic stem cells is possible, say researchers

Scientists at the Danish Stem Cell Center, DanStem, at the University of Copenhagen have discovered that they can make embryonic stem cells regress to a stage of development where they are able to make placenta cells as well as the other fetal cells.

Researchers discover TRF1 gene that is important for nuclear reprogramming

Researchers are still fascinated by the idea of the possibility of reprogramming the cells of any tissue, turning them into cells with the capacity to differentiate into cells of a completely different type- pluripotent cells-and they are still striving to understand how it happens.

CSIRO scientists develop test to identify unsafe iPS cells

CSIRO scientists have developed a test to identify unsafe stem cells. It is the first safety test specifically for human induced pluripotent stem cells - as published today in the international journal Stem Cells.

Transplantation of human stem cells improves muscle function in rats used to model ALS

Transplantation of human stem cells in an experiment conducted at the University of Wisconsin-Madison improved survival and muscle function in rats used to model ALS, a nerve disease that destroys nerve control of muscles, causing death by respiratory failure.

Single injection of human neural stem cells improves acute spinal cord injuries in rats

An international team led by researchers at the University of California, San Diego School of Medicine reports that a single injection of human neural stem cells produced neuronal regeneration and improvement of function and mobility in rats impaired by an acute spinal cord injury.
