The experiment, still in its early stages might be able to expand to lab-grown human organs which will probably save thousands of lives.
During the experiment, the researchers in the US injected human stem cells into early-stage pig embryos. Then, these hybrid embryos were placed into surrogate sows and allowed to develop until the first trimester.
The results were astonishing. More than 150 embryos ended up developing in chimeras with having human cell count as 1 in 1,000 hybrid cells in the developing embryos. This meant that they had developed the precursors of organs including the heart and liver.
This is a viable concept with an evidence which shows that human-pig hybrids are possible. This means there’s a good possibility of lab-grown human parts for transplants who need them.
