Scientists Move Closer to Creating Human Eye from Stem Cells

"A breakthrough in stem cells just brought us much closer to lab-grown human eyeballs," says Popular Mechanics. "Biologists led by Kohji Nishida at Osaka University in Japan have discovered a new way to nurture and grow the many separate tissues that make up the human eyeball, and the scientists need only a small sample adult skin to build them all. Using their new method, Nishida's team can grow retinas, corneas, the eye's lens, and more. In a preliminary trial, the Japanese researchers cultured and grew sheathes of rabbit cornea—the transparent cover of the eye— that restored sight in blind rabbits born without fully-grown corneas. The research is published today in the journal Nature. Don't throw away your glasses (or eye patch) just yet, but human trials are up next." Read more.
