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.

Columbia Studies Uncover Misidentification of Gut Stem Cells

Two independent studies by Columbia scientists suggest that research into the gut's stem cells over the past 15 years has been marred by a case of mistaken identity: Scientists have been studying the wrong cell.
