Pig organs transplanted to monkeys, another new advance in cross-species transplantation
Multiple organs and tissues, including liver, kidney, heart, abdominal wall, cornea, bone, median nerve, etc., from a gene-edited pig were transplanted to seven recipient monkeys. "The study is another useful exploration and positive attempt to find out whether xenotransplantation of tissues and organs is feasible to be applied to emergency treatment of severe tissue destruction and organ failure, which will further expand the feasibility and effectiveness of confirming the application of xenotransplantation to medical rescue." At the media conference held on the 10th, Dou Kefeng, an academician of the Chinese Academy of Sciences, gave a high evaluation of the operation.

Miracle! Man's thumb was severed for 76 hours, successfully resuscitated
Recently, a banner full of patients' gratitude was sent to the hands of hand and foot surgeons of Qilu Hospital. It turned out that, just more than twenty days ago, Mr. Lu's left thumb was cut off by a machine while he was working at a construction site. The incident was sudden, and the severed finger could not be found during the emergency medical treatment. Two days later, the possibility of being separated from the broken finger and then pick up the living is minimal.

Cryopreservation is known as the technique of solidifying time, by cooling biological materials (e.g. cells, tissues and organs) to low temperatures with the addition of cryoprotectants (generally -196°C liquid nitrogen preservation), and then rewarming them to normal temperatures (37°C) in an effective manner when needed, at which time the biological samples can still be restored and maintain their activity.

Breaking! U.S. transplants pig kidneys to humans, now surviving for over a month
As we all know, organ transplantation, as the last resort treatment for many end-stage organ diseases, has long been in an objective situation where demand far exceeds supply (organ donation). As a result, many research teams have also put their hopes for a breakthrough in the field of xenotransplantation - trying to make pig hearts, pig kidneys and pig livers work in the human body.

Spinal cord-like tissue transplantation helps paralyzed rats regain motor function
Dai Jianwu, a researcher at the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences (IGDB, CAS), and Yannan Zhao, a young researcher, have made a new progress in the study of in vitro fabrication of human spinal cord tissues, which, when transplanted, help to restore motor functions in paralyzed rats. The related study was recently published in Science Advances.

The real-life version of "Avatar" is here! Scientists create human organs with chips
In medical research laboratories, we often see small animals such as mice, rabbits or frogs, which are used as animal models to become experimental, drug-testing or even anatomical objects, and make great sacrifices for human medical research.
