tissue rejection will not be a problem if the tissue to be transplanted comes from the same person.
Tissue matching is important in organ transplantation to minimize the risk of rejection by the recipient's immune system. Matching donor and recipient tissue types can help reduce the likelihood of immunological reactions and improve the success of the transplant. It also helps to increase the long-term survival of the transplanted organ.
when you rejact a tissue
after a graft or transplant, the immune response of the recipient to foreign tissue cells, with production of antibodies and eventually destruction of the transplanted organ. acute rejection , acute cellular rejection , cellular rejection.
A tissue graft can be rejected by the body if the immune system recognizes it as foreign and attacks it. This immune response can be triggered by differences in genetic markers between the donor and recipient, leading to rejection. Inadequate matching of the donor tissue with the recipient can also contribute to rejection reactions.
T lymphocytes
Every person has a different type of tissue. If the tissue from the donor is too different from the patient's tissue, the patient's immune system will try to destroy this new tissue because it is considered a "foreign substance". Therefore inserting incompatible tissue would defeat the purpose of the treatment and further weaken the patient's immune system. So, doctors are very careful which type of tissue used in these therapies to insure a positive result.
Immunosuppressant
autoimmune medication such as azathiroprine
It contains few cells and no blood vessels.
MHC molecules of the host may stimulate rejection of the graft tissue :]
Tissue rejection occurs because the body does not recognize the tissue as compatible. This can be because the proteins are different for example.
