iMPCs: Cell Reprogrammers Take Aim at Liver Disease

Over the past few years, researchers have learned how to reprogram skin or blood cells into induced pluripotent stem cells (iPSCs), which have the ability to differentiate into heart, nerve, muscle, and many other kinds of cells. But it’s proven a lot more tricky to coax iPSCs (as well as human embryonic stem cells) to differentiate into mature, fully functional liver cells.
Now, NIH-funded researchers at the University of California, San Francisco (UCSF) and the Gladstone Institutes appear to have overcome this problem. They have developed a protocol that transforms human skin cells into mature liver cells that not only function normally in a lab dish, but proliferate…
