Last week, Japanese scientists announced they had developed a new way to create stem cells. On my America Weekend show, biologist Dr. Paul Knoepfler explained why this discovery could be a game-changer because it makes the stem cell process so much faster and could lead to a day in the not-so-distant future when, using our own blood cells as a starter kit, we can get replacement body parts out of 3-D printers. It also creates an end-run against those who complain about harvesting embryonic stem cells.
