Can human organs be grown in pigs?

A new approach to generating human organs in the lab took a step forward this week. You may have seen the headline, "Scientists create a part-human part-pig embryo." It's more complicated than that, but it does involve cross species hybrids. The goal is to create custom organs that can be safely transplanted into humans who need them to survive. That's according to Antonio Regalado, editor for biomedicine at MIT Technology Review.
