Final answer:
A skin graft taken from another individual or cadaver is called an allograft, which has risks of being rejected due to immune system recognition of foreign cells. However, scientific advancements may lead to growing organs from a patient's own cells, eliminating rejection risks.
Step-by-step explanation:
A skin graft taken from another person or cadaver is referred to as an allograft. This biological concept revolves around the transplantation of organ or tissue, where the goal is to replace a damaged or missing part of the body. Allografts involve tissue transplanted from one genetically distinct individual to another within the same species, such as skin from a cadaver being used to repair another person's burn. However, this procedure carries the risk of transplant rejection due to the immune system recognizing the donor tissue as foreign. The likelihood of rejection is associated with the presence of different human leukocyte antigens (HLAs) on the transplanted cells, which can be identified as non-self by the host's immune system.
On the other hand, advancements in science may lead to techniques that allow growing new organs in vitro from an individual's own harvested cells, known as autologous cell cultures. Such organs would not be recognized as foreign when transplanted, thereby eliminating the risk of rejection.
