Stem Cells News and Research

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.

Tissues derived from embryonic stem could help to overcome immune rejection problems

Tissues derived from embryonic stem (ES) cells could help to pacify the immune system and so prevent recipients from rejecting them, the UK National Stem Cell Network Science Meeting heard last week.

Inserting tiny scaffolding into the brain could dramatically reduce damage caused by strokes

With funding from the Biotechnology and Biological Sciences Research Council (BBSRC) neurobiologists from the Institute of Psychiatry and tissue engineers from The University of Nottingham have joined forces to tackle the challenge of tissue loss as a result of stroke.

Stem cells and cancer: cancer pathways that also control the adult stem cell population

Speaking at the UK National Stem Cell Network Annual Science Meeting in Edinburgh, Professor Alan Clarke from Cardiff University described his work to investigate a mechanism that normally drives adult stem cells to repair the intestine.

Scientists uncover the potential to control adult stem cells

Research presented at the UK National Stem Cell Network Annual Science Meeting in Edinburgh represents a step towards the use of Adult Stem Cells (ASCs) to repair damaged tissue.

Developing cancer treatments directed at critical developmental pathway

Researchers from the University of Pennsylvania School of Medicine and colleagues discovered that the Notch signaling pathway, which determines the development of many cell types, and is also implicated in some cancers, is not universally essential for the maintenance of stem cells.

Computational approaches to the role of epigenetic marks in transcription regulation

A closer alliance between computational and experimental researchers is needed to make progress towards one of biology's most challenging goals, understanding how epigenetic marks contribute to regulation of gene expression.

Discovery of gene involved in blood stem cell replication, movement

Researchers at the Joslin Diabetes Center have identified a gene that is responsible for the division and movement of marrow-derived, blood-forming stem cells, a finding that could have major implications for the future of bone marrow and blood cell transplantation.

Soy appears to protect against development of breast cancer

Evidence is growing from animal and human studies that genistein, a potent chemical found in soy, protects against development of breast cancer - but only if consumed during puberty, says a Georgetown University Medical Center researcher in the British Journal of Cancer published online today.

Better understanding of how T-cell leukemias and other disorders arise

Contrary to the currently accepted model of T-cell development, researchers at the University of Pennsylvania School of Medicine have found that juvenile cells on their way to becoming mature immune cells can develop into either T cells or other blood-cell types versus only being committed to the T-cell path.

Scientists turn normal skin cells into cancer stem cells

With a bit of genetic trickery, researchers at the Stanford University School of Medicine have turned normal skin cells into cancer stem cells, a step that will make these naturally rare cells easier to study.

Discovery of a critical early player in the path that turns cells to fat

Given that obesity - defined as an excess amount of body fat relative to lean body mass - is a major health concern in the United States and an increasing problem in the developing world, such a fuller understanding of the molecular processes governing fat tissue formation could ultimately hold clinical importance, according to the researchers.

Parkinson transplants survive at least 16 years

Transplanted cells can survive in the brain for over one and half decade. However, some of the transplanted cells developed Parkinson-like features which is very surprising.
