stem cell

One EMRI of the new findings of medical knowledge is identify and separate a new type of cells in the body of mammalian, called stem cells. As these cells have high potential in the field of division, differentiation to the specialized cells and ability of repairing tissues, these cells have extremely absorbed the attention of scientists. Adult stem cells which exist in different organs of after birth tend to be converting to the same tissue cells which it belongs to. For instance hematopoietic cells in the bone marrow that are known as hematopoietic stem cells have tend to become blood cells such as red blood cells, white blood cells and platelets.

 
In recent years many research have done to investigate the possibility of converting stem cells of a specific tissue into aspecialized cells of completely different tissue; this process known as “plasticity”. For example, conversion of bone marrow stem cells into neurons or conversion of liver stem cells into insulin producing cells or conversion of hematopoietic stem cells into heart muscle cells. Therefore, the possibility of using adult stem cells for cell-based therapy (Cell Therapy) has dedicated one of the most important medical research topics in the world
