TED-ED: How bones make blood - Melody Smith

The video explains the journey of blood cells originating from bone marrow, highlighting the role of stem cells in differentiating into various blood cells. It discusses blood cancers, often caused by genetic mutations in stem cells, and the potential cure through allogeneic bone marrow transplants. The transplant process involves extracting stem cells from a donor, preparing the recipient with chemotherapy or radiation, and infusing donor cells. Risks include graft versus host disease and the need for genetic matching. Donor registries play a crucial role in finding matches, with a simple cheek swab being sufficient for registration.
