Bone marrow transplantation is an example of a stem cell therapy that is in widespread use.
Human umbilical cord blood (HUCB) is considered to be the most plentiful reservoir of cells and to have regenerative potential for many clinical applications.
Alternate methods for preparing stem cells include genetic reprogramming of adult cells (called iPSCs, induced pluripotent stem cells) to assume a stem cell-like state.
Research is underway to determine whether stem cell therapy may be useful in treating a wide variety of conditions, including diabetes, heart disease, Parkinson's disease, and spinal cord injury.
