Organ transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The donor and recipient may be at the same location, or organs may be transported from a donor site to another location.
The donor heart and lungs are positioned and sewn into place. As the donor organs warm up to body temperature, the lungs begin to inflate. The heart may fibrillate at first - this occurs because the cardiac muscle fibres are not contracting synchronously. Internal paddles can be used to apply a small electric shock to the heart to restore ...
Xenotransplantation (xenos-from the Greek meaning "foreign" or strange [1] [2]), or heterologous transplant, is the transplantation of living cells, tissues or organs from one species to another. [3] Such cells, tissues or organs are called xenografts or xenotransplants .
Hence, similar tissue from another part of the body that is in excess is sourced as the autograft. [10] [11] This can be seen in procedures like autologous orthopedic transplant, which remains the "gold standard" of bone grafting methods through extracting grafts from places like the iliac crest and transplanting them to the targeted fracture ...
A brain transplant or whole-body transplant is a procedure in which the brain of one organism is transplanted into the body of another organism. It is a procedure distinct from head transplantation , which involves transferring the entire head to a new body, as opposed to the brain only.
The kidney came from a special group of pigs bred to produce human-like kidneys. eGenesis, a biotech company that has been studying ways to make animal tissues as human as possible, worked closely ...
One of the earliest mentions about the possibility of a kidney transplant was by American medical researcher Simon Flexner, who declared in a reading of his paper on "Tendencies in Pathology" in the University of Chicago in 1907 that it would be possible in the then-future for diseased human organs substitution for healthy ones by surgery, including arteries, stomach, kidneys and heart.
Scientists think genetically-modified animals could one day be the solution to an organ supply shortage that causes thousands of people in the U.S. to die every year waiting for a transplant.
