The Cell Of Adult Stem Cells

A small subpopulation of the proliferating compartment, consisting of relatively undifferentiated proliferative cells that maintain their population size when they divide, while at the same time producing progeny that enter a dividing transit population within which further rounds of cell division occur, together with differentiation events, resulting in the production of the various differentiated function cells required of the tissue.13
This means that adult stem cells exist in small groups and are mostly undifferentiated, meaning the cells have the capability to change into one or more cell types over time. While adult stem cells can be pushed to differentiate into different cell types, they cannot become every cell type in the body. This results in the adult stem cell offspring only being able to develop into only cell types related to the tissue of origin. For example, neuronal stem cells may develop into nerve cells of the brain or spinal cord, but not into cells of other organs, such as the liver. Adult stem cells are also capable of homing to specific environments in the body and regenerating functional tissue after injury.14 These additional functions of adult stem cells make them ideal candidates for therapeutic stem cell medicine because they are able to be used in specific patients to help rebuild damaged tissue, providing the patient with a better quality of life.
Stem cells can become many different types of cells, they provide researchers the ability to look
