Scientists Grew Tiny, Partially Functional Human Intestines Inside Mice

To better understand our organs and perform tests on a more human-like proxy, researchers are increasingly turning to organoids: miniaturized tissue cultures, usually in the form of organs, that are made from stem cells.And a recent study, published in the journal Nature Biotechnology, may have just pushed the envelope by growing organoid human intestines with a working immune response inside mice.
