What is the procedure for a bone marrow transplant

Bone marrow transplantation can be divided into autologous bone marrow transplantation and allogeneic hematopoietic stem cell transplantation according to the source of hematopoietic stem cells. Autologous bone marrow transplantation (autologous hematopoietic stem cells) is a process in which the patient's hematopoietic stem cells are removed in advance and frozen in liquid nitrogen. After pretreatment, the user quickly dissolves the frozen hematopoietic stem cells and then transfuses them back into the user's body. This is autologous hematopoietic stem cell transplantation.

Allogeneic hematopoietic stem cell transplantation (allogeneic hematopoietic stem cell transplantation) requires the user's peripheral blood to be extracted in advance, and then the bone marrow bank to find out whether there is a suitable match. If there is a complete bone marrow match, the user will undergo a pretreatment program, and then the donor's hematopoietic stem cells will be taken out and transfused back into the user's body, so that the hematopoietic stem cells of others can be reconstructed in the user's body. This is allogeneic hematopoietic stem cell transplantation.
