Patients receive one of two types of stem cell - based transplants: autologous, in which a patient donates and receives back his / her own stem cells; or allogeneic, in which bone

matched with those of a patient.
Kimmel Cancer Center bone
marrow transplant researchers pioneered the haploidentical version of the therapy to help patients who do not have
matching donors.
Bone
marrow is easy to extract from patients, and the therapeutic cells derived from it are a perfect genetic
match for patients, greatly reducing the risk of tissue rejection.
