5 questions tagged Stem Cells — spanning every one of the seven Ws.
What are stem cells?
Stem cells are cells that can self-renew and develop into specialized cell types. They are important in development and tissue repair.
What are induced pluripotent stem cells?
Induced pluripotent stem cells, or iPSCs, are adult cells reprogrammed back into a stem-cell-like state. They can then be turned into many other cell types.
What are stem cells in bone marrow?
Bone marrow stem cells are blood-forming stem cells that generate red cells, white cells, and platelets. They are the source of lifelong blood cell renewal.
When was the first human stem cell transplant performed?
The first successful human stem cell transplant was effectively the first bone marrow transplant in 1956, with stem-cell biology understood later.
How do stem cells replace damaged tissues?
Stem cells can self-renew and also become specialized cells. This lets them repair tissues such as blood, skin, and the gut.
