Engineering better hair transplants

Cell-based approach to new follicles takes hold in skin

A hair-raising trick may lead to better hair transplants. Engineered hair follicles patched into skin can be coaxed to connect to surrounding tissue and to grow hair in an organized way, a study in mice finds.

Bioengineered follicles can grow hair (as seen on the mouse’s head) when transplanted into normally hairless mice, a new study shows.
