I think this is what we were talking about (it's been 5 years so a little foggy). Basically you can now use any cell and through a process turn it into an "embryo" that will grow however it's manipulated to grow. So they could take cells from your arm and grow it into a mock embryo, implant it in a womb, and through the magic of science way over my head grow an eyeball...no human fetus needed.
