The world's first rat's foot from a bioreactor

By placing a "frame" made from a damaged limb and stem cells of muscles, blood vessels and connective tissue in a special bioreactor, scientists received a full-fledged limb in a few weeks, with the exception of nerves missing in it.

Homunculi instead of guinea pigs

The idea of creating an "artificial human" Homunculus is simple and this makes it even more ingenious: to place human cells on a plate the size of a credit card and combine them with a system of "vessels" in the likeness of a living organism.
