Researchers have successfully grown a humanized kidney inside a pig, a development that could help address the shortage of organs for transplantation. The study involved creating human-pig chimeric embryos and implanting them in surrogate pig mothers. After 28 days, the resulting kidneys had a predominantly human cell composition. While the achievement is significant, there are limitations to the study, including concerns about the efficacy of the procedure and the contribution of human cells to other lineages.

The new work is a "big step forward" in finding new ways to generate viable organs for human transplants, but it comes with some ethical considerations

Transplant organs are scarce. Could growing ones with human cells in pigs alleviate the shortage?
