"Human organs in animals" to end shortage crisis

🐷👤 The progress of the century! Scientists are building "human organs in animals" to end the crisis of transplant organ shortage! 🧬

This is a milestone that could change the face of medicine forever by developing a "human-animal Chimeras" that can create organs compatible with the human body to save the lives of hundreds of thousands of patients waiting for hope!

In the United States alone, more than 100,000 people are waiting for transplants, so solving this problem is a top priority.

🔑 The Key to Success: Closing the Immune Switch of the Host Animal

Creating a human-pig or rat hybrid is not easy, because the host cell's defense system opposes and defeats the human cell, making complete organ formation difficult.

But most recently! A team of biologists at UT Southwestern has found a groundbreaking way:

* They found a protein in a rat cell called "MAVS."

* When the MAVS protein is deactivated (disabled), it acts to "turn off the immune alarm" of the host cell down!

* It is this switch that allows human cells to survive, compete, and integrate more effectively into animal embryos without the need to modify human donor cells at all!

🌟 From Lab to Real Life: Transplantation

Although the ethical issue of human-animal kaimya is still being debated, the introduction of genetically engineered pig-grown organs into human transplantation (Xenotransplantation) has expanded and produced remarkable results in recent years:

* March 2024: Massachusetts General Hospital successfully transplants a genetically amputated pig's kidney to a living recipient for the first time.

* Other successes have been consistently reported, such as cross-transplantation in patients with terminal kidney cancer.

This is a momentous new hope that will help the medical community finally resolve the long-prolonged organ shortage!

Do you think this technology will truly solve the problem of organ shortage? Let's comment!
