Autologous transplantation
Autologous Transplantation
Autologous transplantation (pronunciation: au·tol·o·gous trans·plan·ta·tion, /ɔːˈtɒləɡəs trænsplɑːnˈteɪʃən/) is a medical procedure where cells, tissues, or even organs are removed from an individual and then returned to the same individual after a period of time. This procedure is often used in the treatment of various diseases, including cancer and autoimmune disorders.
Etymology
The term "autologous" is derived from the Greek words "auto" (self) and "logos" (study), indicating that the procedure involves the use of the patient's own cells or tissues. The term "transplantation" comes from the Latin "trans" (across) and "plantare" (to plant), referring to the act of moving cells, tissues, or organs from one place to another.
Types of Autologous Transplantation
There are several types of autologous transplantation, including:
- Autologous Stem Cell Transplantation: This involves the collection of stem cells from the patient's blood or bone marrow, which are then returned to the patient after high-dose chemotherapy or radiation therapy.
- Autologous Chondrocyte Implantation: This is a procedure used to treat cartilage defects, particularly in the knee. It involves the removal of cartilage cells from the patient, which are then grown in a lab and re-implanted into the patient.
- Autologous Blood Transfusion: This involves the collection and storage of a patient's own blood prior to a surgical procedure, which is then transfused back into the patient during or after the surgery.
Related Terms
- Allogeneic Transplantation: This is a type of transplantation where the donor and recipient are different individuals.
- Hematopoietic Stem Cell Transplantation: This is a procedure where stem cells are infused into a patient to produce new blood cells. It can be either autologous or allogeneic.
- Graft-versus-Host Disease: This is a complication that can occur after an allogeneic transplant, where the donated cells attack the recipient's body.
