A longer, better ride with engineered stem cells.

A television series called Pimp My Ride depicts the transformation of run-down, shabby automobiles into fantasy-lands of extreme color and function customized to the owner’s interests, with built-in light shows, clothes dryers, sound studios, and movie theaters. At the end of each episode, we are presented with a dazzlingly transformed, attention-getting vehicle. However, the viewer usually does not see how well the revamped car performs or how long it stays on the road.
