Homograft, Allograft

Homograft and Allograft are types of transplantation where living tissue or organ is transplanted from a donor to a recipient belonging to the same species. For example, one person's heart can be transplanted into another. However, unlike autotransplantation, where tissue or an organ is transferred from one part of the body to another in the same person, homograft and allograft require suppression of the rejection reaction of foreign tissue.

A homograft comes from a donor who is genetically identical to the recipient. For example, identical twins are ideal donors for homotransplantation. However, in most cases, homografts are taken from other donors.

An allograft comes from a donor who is genetically different from the recipient but belongs to the same species. For example, one person's heart or kidneys can be transplanted into another person.

However, with allotransplantation there is a risk of tissue or organ rejection because the recipient's immune system sees the donor tissue or organ as foreign and tries to get rid of it. This rejection reaction can lead to graft failure and deterioration of the recipient's health.

To prevent rejection, recipients must take immunosuppressive medications, which suppress the immune system and protect the graft from rejection. However, these medications may have side effects, such as increasing the risk of infections and tumors.

Apart from homotransplantation and allotransplantation, there are other types of transplantation such as xenotransplantation, where tissue or organ is transplanted from one species to another, and autotransplantation, where tissue or organ is transferred from one part of the body to another in the same person.

In conclusion, homograft and allograft are important treatment options for people with various diseases that require tissue or organ transplantation. However, these procedures require close monitoring and appropriate treatment to ensure maximum effectiveness and minimize health risks to the recipient.



Homotransplant (Homotransplant; Greek homos - the same, similar; transplant - to transplant), allotransplant, xeno-transplant is a living transplant of tissue or organ from the human body (donor), having functional value, intended for transplantation into the body of another person ( recipient).

Examples of living grafts:

1. Kidney (human). And also an intestinal transplant. This is an intestinal transplant, i.e. part of the intestine of a healthy person is removed from the donor himself and placed in the abdominal cavity of the patient. Subsequently, this section of the intestine begins to function and perform its functions. This process of introducing a portion of a healthy patient's intestine into the human body as part of a transplant is called an intestinal allograft. Transplanted organs and tissues taken from a living person are called living grafts, and those taken after the death of a person or animal are called cadaveric tissue. Due to their nature, living grafts are always a subject of debate. They were also called biofactory embryos. Such technologies have been seen as a potential method for obtaining significant quantities of organs for transplantation. However, this method turned out to be environmentally unacceptable, because as a result



Homograft is the transplantation of living tissue or organs that is carried out between two individuals of the same species. Recipients and donors belong to the same species. An example of such a transplant is a heart transplant from one person to another. If the immune system's rejection reactions are not suppressed through special medications, then this type of transplant will not be productive. The transplanted organ or tissue for the operation must be selected carefully so that many

Homograft, Allotransplant (Alloaoplast) is a transplantation of living tissue that serves to replace natural organs or tissues. Both types of transplants may have both advantages and disadvantages.
