Stem cell or Bone Marrow transplantation is done with two methods- Autologous and Allogenic. In Autologous, the stem cells and the bone marrow used for the surgery are the person’s own. The cells are stored and frozen before the transplant. After the transplantation, the cells are given back through the veins.
In Allogenic, stem cells of someone else and with whom the tissue matches are used for the transplant. The suitable donor can be siblings or the closest relative.
