Stem cell has significant benefits despite the controversies surrounding it. Do take a look at the link in the video.
In a momentous development researchers have created a hybrid part-human part-pig embryo for the first time in human history.
The study has been published in the journal Cell.
Researchers were successfully able to inject human stem cells into a pig embryo and grow tissues which would ultimately form the early stages of organs, such as the human liver, heart, and even neurons.
Although the research is in very early stages, experts believe this development could one day be used to grow transplantable human organs in animals, including pigs.
In another development that adds to this scientific breakthrough, in an altogether separate study published in the Nature, an international team of researchers were able to successfully perform an interspecies organ transplant to create a hybrid rat-mouse embryo.
In this study, the researchers were able to grow pancreas inside a rat embryo which was later transplanted into diabetic mice.
As noted by the Washington Post, the new transplanted pancreas cured the mice’s diabetes without being rejected by the host.
Incredibly, all the mice needed was a few days of recovery and immunosuppressive treatments and voila, they were then able to resume their normal healthy lives.
Although these developments have great promise, the ethics of harvesting human organs from animals, or even that of creating hybrid human-animal chimeras is a sensitive subject.
Apart from the philosophical and symbolic questions that typically arise from such issues, there is a fear that research in stem cells could one day create an animal with a human brain.
However, for now, that possibility is only in the realms of science fiction, and the Cell study takes pains to point out that the system is currently “highly inefficient”.
Nevertheless, both papers show the positive aspects of this research.
