Determine the type of tissue grafts that would be most unlikely to experience rejection and explain why
What will be an ideal response?
Two types of graphs would be least likely to trigger rejection: autografts and isografts. Autografts involve tissue transplanted from one site to another in the same individual. Examples of autografts include skin grafts, in which skin is removed from one part of the body and placed on another part to repair skin damaged by trauma such as burns. Isografts involve organs and tissues transplanted between two genetically identical individuals. These are relatively uncommon due to the small number of identical twins. Autografts and isografts result in no response from TC cells because the antigens bound to class I MHC molecules are not recognized as foreign.
