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.

Research using human embryonic stem cells reveals earliest step in human development

Researchers at Johns Hopkins have uncovered the molecular underpinnings of one of the earliest steps in human development using human embryonic stem cells.

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.

Tiny scaffolding inserted into brain could reduce damage caused by strokes

Inserting tiny scaffolding into the brain could dramatically reduce damage caused by strokes the UK National Stem Cell Network Annual Science Meeting will hear today (10 April).

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.

Potential new therapy for myeloproliferative disorders

A unique partnership between industry and academia has led to human clinical trials of a new drug for a rare class of blood diseases called myeloproliferative disorders (MPD), which are all driven by the same genetic mutation and can evolve into leukemia.

Identification of dopamine 'mother cells' could lead to future Parkinson's treatments

'Mother cells' which produce the neurons affected by Parkinson's disease have been identified by scientists, according to new research published in the journal Glia.

New mouse model grants insight into the genetic and molecular mechanisms underpinning acute myeloid leukemia

Leukaemia - cancer of blood or bone marrow is caused by mutations that allow defective blood cells to accumulate and displace healthy blood.

Transplanted dopamine neurons are affected by the Parkinson's disease process

A new groundbreaking study published in Nature Medicine has implications for the future of transplantation and stem cell therapies as a treatment for Parkinson's disease.

Reconstructing mandibular defects with bioengineered tooth and bone

Current strategies for jaw reconstruction require multiple procedures, first to repair the bone defect to offer sufficient support, and then to place the tooth implant.

Fetal cells transplanted into the brain to treat Parkinson's may not function long term

Neurons grafted into the brain of a patient with Parkinson's disease fourteen years ago have developed Lewy body pathology, the defining pathology for the disease, according to research by Jeffrey H. Kordower, PhD, and associates and published in the April 6 issue of Nature Medicine.
