When the cells are collected from the same patient on whom they will be used, a graft is called autologous. Syngeneic refers to a graft transferred between genetically identical animals or people. [1] A syngeneic graft is known as an isograft. [2] Related terms include: [citation needed]
A more recent clinical trial showed that allogeneic fetal MSCs transplanted in utero in patients with severe OI can engraft and differentiate into bone in a human fetus. [41] Besides bone and cartilage regeneration, cardiomyocyte regeneration with autologous BM MSCs has also been reported recently.
A common example is the removal of a piece of bone (usually from the hip) and its being ground into a paste for the reconstruction of another portion of bone. Autotransplantation, although most common with blood, bone, hematopoietic stem cells, or skin, can be used for a wide variety of organs. One of the rare examples is autotransplantation of ...
Haematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent haematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [10] [11] [12] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical ...
Unlike other organs, bone-marrow cells can be frozen (cryopreserved) for prolonged periods without damaging too many cells. This is a necessity with autologous HSCs because the cells must be harvested from the recipient months in advance of the transplant treatment.
The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts. It is contrasted with autotransplantation (from one part of the body to another in the same person), syngenic transplantation of isografts (grafts transplanted between two genetically identical individuals) and ...
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
Autologous stem-cell transplantation is distinguished from allogenic stem cell transplantation where the donor and the recipient of the stem cells are different people. [2] It can be also used as an Assisted reproductive technology to improve the reproductive outcomes. In a first step the bone marrow derived stem cells are mobilized.
