Blood Transplantation, Thrombosis and Hemostasis

Blood or bone marrow transplant replaces abnormal blood-forming stem cells with healthy cells. When the healthy stem cells come from you, the procedure is called an autologous transplant. When the stem cells come from another person, called a donor, it is an allogeneic transplant.

Thrombosis is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. Hemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel. It is the first stage of wound healing.
