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.

Ethically universal stem cell lines

Human embryonic stem cells (hESC), those very young cells that are a biological blank slate, have the potential to become more specialized, contributing to the workings of a wide variety of organs and tissues.

Reprogrammed fibroblasts resemble embryonic stem cells

Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells, including the ability to give rise to multiple cell types and contribute to the germline.

Aging stem cells in mice may hold answers to diseases of the aged

As stem cells in the blood grow older, genetic mutations accumulate that could be at the root of blood diseases that strike people as they age, according to work done in mice by researchers at the Stanford University School of Medicine.

Researchers track human stem cells transplanted into rat brain

Researchers at the Stanford University School of Medicine have illuminated the path taken by human neural stem cells that were transplanted into the brains of rats and mice, and found that the cells successfully navigate toward areas damaged by stroke.

Existence of muscle-building stem cells points to regenerative therapies for muscular disease

A new report in the June 1 issue of the journal Cell, a publication of Cell Press, confirms the existence of some apparently uncommitted stem cells amongst cells responsible for generating the bulging biceps of body builders and the rippling abs of fitness buffs.

New adult nerves have a deeper role than simply replacing dead ones

You may not be able to relive your youth, but part of your brain can. Johns Hopkins researchers have found that newly made nerves in an adult brain's learning center experience a one-month period when they are just as active as the nerves in a developing child.
