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.

New class of tumor-targeting agents can seek out dozens of solid tumors

Scientists at the University of Wisconsin Carbone Cancer Center (UWCCC) report that a new class of tumor-targeting agents can seek out and find dozens of solid tumors, even illuminating brain cancer stem cells that resist current treatments.

Study presents oxytocin as latest treatment target for age-related muscle wasting

Researchers at the University of California, Berkeley, have discovered that oxytocin -- a hormone associated with maternal nurturing, social attachments, childbirth and sex -- is indispensable for healthy muscle maintenance and repair, and that in mice, it declines with age.

Researchers create three-dimensional complement of human retinal tissue in a dish

Using a type of human stem cell, Johns Hopkins researchers say they have created a three-dimensional complement of human retinal tissue in the laboratory, which notably includes functioning photoreceptor cells capable of responding to light, the first step in the process of converting it into visual images.

Protein may be key to maintaining health of aging blood stem cells

A protein may be the key to maintaining the health of aging blood stem cells, according to work by researchers at the Icahn School of Medicine at Mount Sinai recently published online in Stem Cell Reports.

Researchers identify critical weakness of invasive cancer cells

Metastatic cancer cells, which can migrate from primary tumors to seed new malignancies, have thus far been resistant to the current arsenal of anticancer drugs.

Regeneration of a chronically diseased liver may be possible, say Harvard researchers

Harvard Stem Cell Institute scientists at Boston Children's Hospital have new evidence in mice that it may be possible to repair a chronically diseased liver by forcing mature liver cells to revert back to a stem cell-like state.

Study sheds light on new potential treatment for heat stroke

Scientists in Taiwan have found that intravenous injections of stem cells derived from human exfoliated deciduous tooth pulp (SHED) have a protective effect against brain damage from heat stroke in mice. Their finding was safe and effective and so may be a candidate for successfully treating human patients by preventing the neurological damage caused by heat stroke.

Berkeley Lab scientists identify why older women are more susceptible to breast cancer

Scientists from the Department of Energy's Lawrence Berkeley National Laboratory have gained more insights into why older women are more susceptible to breast cancer. They found that as women age, the cells responsible for maintaining healthy breast tissue stop responding to their immediate surroundings, including mechanical cues that should prompt them to suppress nearby tumors.

ImStem successfully treats animal model of multiple sclerosis using hESC

ImStem Biotechnology, Inc. (ImStem) announced today it has successfully treated an animal model of multiple sclerosis (MS) using human embryonic stem cells (hESC) derived mesenchymal stem cells (MSCs), called hES-MSCs.

RPB grants $500,000 to accelerate treatments for Retinitis Pigmentosa

Research to Prevent Blindness (RPB), the leading eye research foundation, is providing $500,000 to accelerate the development of treatments for Retinitis Pigmentosa (RP) -- a family of retinal diseases that progressively create extreme tunnel vision, loss of night vision and leave affected patients legally blind by the age of 40.

Scientists reproduce chromosomal modifications in human cells that cause certain cancer

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) and the Centro Nacional de Investigaciones Oncol-gicas (CNIO) have succeeded in reproducing, in human cells, the chromosomal translocations that cause two types of cancer: acute myeloid leukemia and Ewing's sarcoma.
