Scientists have found a way for humans to accept transplanted animal body parts more easily, the BBC News reported Monday.
Since human organs are in short supply and demand, and transplant patients often wait long periods of time, this could solve many problems, said researchers at the University of Leeds in England.
In a study, scientists stripped animal tissues of cells and molecules that usually trigger a rejection response from human immune systems using methods of freezing, chemical baths and ultrasounds.
This left a biological scaffold, which could then be inhabited by cells from the patient’s own body, creating tissues that carry no risk of rejection – meaning the cells could be repaired and grow within the body.
Professor John Fisher of the University of Leeds said tests have only been done on animals, but he expects to carry out clinical trials on humans within the next year.
Currently, some animal tissues are transplanted into humans, such as chemically-treated heart valves from pigs, but with limited effectiveness.
