Japanese researchers have grown skin tissue that not only includes hair follicles, but all the glands that come with it — including oil and sweat glands. The trick was to take cells from mouse gums, turn them into stem cell-like forms that generate skin, and implant those into mice with immune system deficiencies (which lets the new skin grow unimpeded). The resulting skin was a little creepy — just look at the wart-like growth above — but it was healthy, behaved normally and made connections with natural tissue.
