Regeneration/Transplantation
Bone, muscle, and joint transplantation/regeneration experiments tested if limbs or joints from one person could be attached to another who had lost that limb or joint. They amputated body parts of one victim and attempted to attach them to other victims. They also removed limbs, bones, and muscles to study regeneration. Attempts to transplant were a failure, and victims suffered excruciating pain and permanent disability.
