How to Make Eyeball Stew

Because the eye is one of the first organs to form during embryonic development, it may be easier to culture using basic ingredients, says Conklin. Therefore, Sasai’s brew may not be easily tweakable for studying the development of other organs. But what this research does show is that it is possible to stimulate early organ growth from the right mix of molecules and stem cells alone.

“The main lesson in all of this is to first see what nature can do by itself when given essentially minimum instructions and the proper environment,” says Conklin. “And, given the right environment, the cells will jump into action.”
