How do bone marrow stem cells differ from differentiated progenitor stem cells ?
Show answer Hide answer
Answer: B. Reconstitution of Bone marrow
Explanation
Bone marrow stem cells possess the remarkable ability to regenerate and completely rebuild the hematopoietic system. Differentiated progenitor cells have more limited developmental potential and cannot achieve full tissue reconstitution independently. Self-renewal capacity allows bone marrow stem cells to maintain their own population while producing mature blood cells. Hematopoietic stem cells reside primarily within the bone marrow cavities of adult human skeletal structures. Progenitor cells are intermediate descendants committed to specific lineages such as myeloid or lymphoid pathways. Transplantation procedures rely entirely on the regenerative power of uncommitted stem cells to restore immunity.
Providing differentiated terminal cells is a function shared by both stem cells and downstream progenitor populations. Formation of the ovum involves germline cellular development and occurs within female reproductive organs instead. Acting as a repair system for the body is a general property characteristic of many cell types.
