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.

Protein can nurture or devastate brain cells, depending on its 'friends,' UT Southwestern researchers find

Researchers at UT Southwestern Medical Center have uncovered new insights into the "Dr. Jekyll and Mr. Hyde" nature of a protein that stimulates stem-cell maturation in the brain but, paradoxically, can also lead to nerve-cell damage.

Discovery of mechanism that regulates the development of stem cells into neurons

Researchers at the University of Southern California (USC) have identified a novel mechanism in the regulation and differentiation of neural stem cells.

Stem cells from umbilical cord blood may help build new heart valves

Children with heart defects may someday receive perfectly-matched new heart valves built using stem cells from their umbilical cord blood, according to research presented at the American Heart Association's Scientific Sessions 2008.

Newborn neurons in the adult brain can settle in the wrong neighborhood

In a study that could have significant consequences for neural tissue transplantation strategies, researchers at the Salk Institute for Biological Studies report that inactivating a specific gene in adult neural stem cells makes nerve cells emerging from those precursors form connections in the wrong part of the adult brain.

First comprehensive genetic blueprint of a forming mammalian organ

Part of an international consortium sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), a research team led by Cincinnati Children's Hospital Medical Center reports the creation of a detailed genome-based atlas for understanding healthy and abnormal kidney development and disease.

Daily rhythms in endothelial cells may explain why heart attacks occur most often in early morning hours

It's not just the stress of going to work. Daily rhythms in the activity of cells that line blood vessels may help explain why heart attacks and strokes occur most often in early morning hours, researchers from Emory University School of Medicine have found.

Arteriocyte awarded DARPA funding for company's blood pharming technology

Arteriocyte announced today a $1,950,000 award from DARPA for the company's Nanofiber Based System (NANEX) technology for the Production of Red Blood Cells project.

Research sheds light on possible role of DNA packaging in cancer development

MIT biologists have discovered that the organization of DNA's packing material plays a critical role in directing stem cells to become different types of adult cells.

10 years of stem cells science

Ten years ago this month (Nov. 6, 1998), the publication in the journal Science of a short paper entitled "Embryonic Stem Cell Lines Derived from Human Blastocysts" rocked biology - and the world - as the all-purpose stem cell and its possibilities were ushered into the limelight.

Advances in use of stem cells for tissue regeneration

A major issue in the development of regenerative medicine is the cell sources used to rebuild damaged tissues.

Scientists confirm a molecular clipping mechanism behind stem cell development

Stem cells don't just become a part of the liver or the brain in a flash; it takes a complex molecular choreography and requires that specific genes be switched on and off at specific times.

Scientists sequence genome of a cancer patient

For the first time, scientists have decoded the complete DNA of a cancer patient and traced her disease - acute myelogenous leukemia - to its genetic roots.

Therapy targeting cyclin D1 protein may block expansion of breast cancer cells

Breast cancer stem cells are known to be involved in therapy resistance and the recurrence of cancerous tumors.

New research sheds light on key trigger of embryonic stem cell differentiation

Clusters of mouse embryonic stem cells called embryoid bodies more closely approximate true embryos in organization and structure than previously thought, according to researchers at the Stanford University School of Medicine.

Scientists identify compounds for stem-cell production from adult cells

In the study, the scientists screened known drugs and identified small molecules that could replace conventional reprogramming genes, which can have dangerous side effects.

Scientists show how "junk" DNA may be a major driver for evolution

In a paper published in Genome Research on Nov. 4, scientists at the Genome Institute of Singapore (GIS) report that what was previously believed to be "junk" DNA is one of the important ingredients distinguishing humans from other species.

$Review of research into how cells and proteins repair fractured bones$

Review of research into how cells and proteins repair fractured bones

A review of research into how cells and proteins repair fractured bones published in the November 2008 issue of The Journal of the American Academy of Orthopaedic Surgeons demonstrates that understanding the biology behind this healing process may lead to improved and less invasive treatments for fractures.

Double-barreled immune cell approach for neuroblastoma

Adding an artificial tumor-specific receptor to immune system cells called T-lymphocytes that target a particular virus extended and improved the cells' ability to fight a form of childhood cancer called neuroblastoma, said researchers form Baylor College of Medicine and Texas Children's Hospital in a report that appears online in the journal Nature Medicine.

Novel scaffold to fix broken hearts

Broken hearts could one day be mended using a novel scaffold developed by MIT researchers and colleagues.

Stem cell therapies for heart disease - one step closer

New research from the University of Bristol brings stem cell therapies for heart disease one step closer. The findings reveal that our bodies' ability to respond to an internal 'mayday' signal may hold the key to success for long-awaited regenerative medicine.
