"Pluripotent" is a long word that means "able to do many things". It is the technical term applied to stem cells that can generate many different sorts of bodily tissue, rather than just one sort, which is all that lesser stem cells can manage. But many researchers hope these cells will be pluripotent in other ways, too. Not only might they be used to make replacement tissues and organs for transplantation into those whose existing body parts no longer work properly (an approach known as regenerative medicine), they might also be used to produce pure cultures of cells for the early testing of drugs. On January 3rd AstraZeneca, a British drug company, said it would buy human heart muscle, blood vessels, nerve cells and liver cells made from iPS cells by Cellular Dynamics, a company founded by James Thomson. Dr Thomson, a biologist at the University of Wisconsin, is the man who led the team that, in 1998, isolated the first human embryonic stem cells and in 2007 published the American version of the iPS work. AstraZeneca has two plans for its purchases. One is to use them to find molecules that encourage non-pluripotent stem cells to turn into mature tissue.
