Heart to Heart with Dan Hart

The heart is an extremely complicated organ, and believe it or not, everyone has one! But how does this vital organ come to be? By studying how a stem cell makes the decision to become a heart cell, Dr. Daniel Hart is trying to figure that out, and he’s using fish to do it. Check out this episode for some pretty terrible puns, fascinating facts about zebrafish, and an extended metaphor about gene regulation that will make you want to reach for the liquor cabinet.
