Yes there is a similar procedure for marrow transplants. It is called 'Haploidentical Transplant' where you only need a half match for marrow transplants which opens the door to parents and children as donors. The procedure requires a 'rebooting' of the immune system which is analogous to the "remove then let it regenerate" approach mentioned in the kidney procedure. I guess the insight comes from the immune system changing to accomodate new organs after it reboots. Its a really interesting area of research. http://www.hopkinsmedicine.org/kimmel_cancer_center/centers/bone_marrow_transplant/haploidentical_transplantation.html http://www.hopkinsmedicine.org/kimmel_cancer_center/centers/...
