Embryonic stem cells might hold the secrets to curing paralysis and brain damage, but they've also garnered plenty of controversy with the anti-abortion lobby because they're harvested from embryos.

"Embryonic stem cell research hasn't kept up pace with adult stem cell research," said Dunn. "Adult stem cell research is advancing so far you might not need embryonic stem cells. [...]"
So while embryonic stem cell researchers are experimenting with rats, adult stem cell researchers have moved on to more advanced tests with humans. The embryonic-based stem cell treatments are probably a decade away, but the U.S. market could see its first adult-based stem cell treatments within the next couple of years.
