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.

Differentiation blocked in tumor stem cells

A new comparison of normal stem cells and cancer stem cells reveals that the cancer stem cells are abnormally trapped at an early stage of development.

New findings on myotonic muscular dystrophy

New research from the University of Virginia Health System shows that, in cases of Type 1 myotonic muscular dystrophy (DM1), a well known heart protein does several surprising things. DM1 is the most common form of muscular dystrophy in adults and affects approximately 40,000 adults and children in the U.S.
