Stem cells may one day be used to make cells and tissues for therapy of many diseases. Studying stem cells may help explain how serious conditions such as birth defects and cancer come about.
These help people with cancer make new blood cells after their own hematopoietic stem cells have been killed by radiation therapy and chemotherapy. Your own cells, donor cells or cells from umbilical cord blood may be used. These cells are used in procedures such as bone marrow transplants. Learn about this procedure that replaces unhealthy bone marrow with stem cells. Stem cells are immature cells that are able to make other blood cells that mature and function as needed. Stem cells are immature cells that are able to make other blood cells that mature and function as needed. They have the potential to become specialized cells, such as muscle cells, blood cells, and brain cellsĭoctors and scientists are excited about stem cells because they could help in many different areas of health and medical research. Every type of blood cell in the bone marrow starts as a stem cell.They are unspecialized, so they cannot do specific functions in the body.They can divide and renew themselves over a long time.Stem cells are different from other cells in the body in three ways: There are two definitions of totipotent stem cells, which reflects the inherent technical difficulty that lies in characterizing them 1: A totipotent cell is a single cell that can give rise to a new organism, given appropriate maternal support (most stringent definition) A totipotent cell is one that can.
There are two main types of stem cells: embryonic stem cells and adult stem cells. They serve as a repair system for the body. Stem cells are cells with the potential to develop into many different types of cells in the body.
