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.

Researchers identify myostatin as potential therapeutic target for muscular disorders

The study of muscular system protein myostatin has been of great interest to researchers as a potential therapeutic target for people with muscular disorders. Although much is known about how myostatin affects muscle growth, there has been disagreement about what types of muscle cells it acts upon. New research from a team including Carnegie's Chen-Ming Fan and Christoph Lepper narrows down the field to one likely type of cell.

Studies in mice reveal how mood-altering drugs may affect brain stem cells

Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells. Apparently, the stem cells "listen in" on the chemical communication among nearby neurons to get an idea about what is stressing the system and when they need to act.

Researchers make major advance in efforts to regenerate damaged hearts

Researchers have made a major advance in efforts to regenerate damaged hearts. Grafts of human cardiac muscle cells, grown from embryonic stem cells, coupled electrically and contracted synchronously with host muscle following transplantation in guinea pig hearts.

Human HLA genes are evolving much more rapidly than previously thought

Human HLA genes - the genes that allow our immune system to tell the difference between our own cells and foreign invaders - are evolving much more rapidly than previously thought, according to an article online on August 3rd in Trends in Genetics. The resulting degree of variation improves our ability to fight off disease, but could also present challenges to current worldwide efforts aimed at identifying potential donors for patients undergoing stem cell transplantation.

New role for oncogenic signaling pathway in embryonic stem cell self-renewal

Researchers at Mount Sinai School of Medicine, the University of Manchester, and the MD Anderson Cancer Center have found a new role for an oncogenic signaling pathway in embryonic stem cell (ESC) self-renewal and in reprogramming adult cells into an ESC-state, which will aid in the development of future cancer therapies.

HSF1 increases expression of chaperones and supports cancer metastasis

Whitehead Institute researchers have found that increased expression of a specific set of genes is strongly associated with metastasis and death in patients with breast, colon, and lung cancers.

Researchers identify how telomerase is recruited to chromosome ends

Stem cells are special. Nestled in muscle and skin, organ and bone, they bide their time over years or decades until called to replace damaged or lost tissue. One secret to their longevity is an enzyme called telomerase, which stills the relentless ticking of the molecular clock that limits the life span of other cells.

SAGE Labs, Autism Speaks expand partnership to create first rat models for translational research

Autism Speaks, the world's leading autism science and advocacy organization, today announced its expanded collaboration with Sigma Advanced Genetic Engineering (SAGE) Labs, an initiative of Sigma- Life, to develop the first rat models with modified autism associated genes, intended to accelerate discovery and translational autism research.

Anacardic acid can rescue some ALS phenotypes in vitro

A research group at the Center for iPS Cell Research and Application (CiRA) at Japan's Kyoto University has successfully recapitulated amyotrophic lateral sclerosis (ALS)-associated abnormalities in motor neurons differentiated from induced pluripotent stem cells (iPSCs) obtained from patients with familial ALS, a late-onset, fatal disorder which is also known for Lou Gehrig's disease. In a drug screening assay using the disease model, the team further found that the chemical compound anacardic acid can rescue some ALS phenotypes in vitro.

New method could increase number of genetic components in synthetic biologists' toolkit

Through the assembly of genetic components into "circuits" that perform logical operations in living cells, synthetic biologists aim to artificially empower cells to solve critical problems in medicine, energy and the environment. To succeed, however, they'll need far more reliable genetic components than the small number of "off-the-shelf" bacterial parts now available.

Population Genetics validates GenomePooling™ for cancer

Population Genetics Technologies Ltd., creator of innovative methods for genetic analyses and biomarker discovery, has successfully completed a pilot study to prove that its GenomePooling™ method is sensitive and accurate enough to detect even small percentages of gene variants within cancer tissue. This validates the method’s suitability for use in IntReALL 2010, the world’s largest genetic analysis of acute lymphoblastic leukaemia (ALL) relapse cases. ALL is the most common childhood malignant disease.
