"I thought I was going to be just drawing blood, not procuring tissue from aborted fetuses," Ms. O'Donnell says. "The harder and more valuable the tissue, the more money you get. So if you can somehow procure a brain or a heart, you're going to get more money than just chorionic villi or umbilical cord. That's basically what it is. So I guess that's an incentive to try and get the hard stuff."
