Researchers discover new class of stem cells

Researchers have identified a new class of lab-engineered stem cells -- cells capable of transforming into nearly all forms of tissue -- and have dubbed them F-class cells because they cluster together in "fuzzy-looking" colonies. The discovery, which was described in a series of five papers published Wednesday in the journals Nature and Nature Communications, sheds new light on the process of cell reprogramming and may point the way to more efficient methods of creating stem cells, researchers say. Due to their extraordinary shape-shifting abilities, so-called pluripotent cells have enormous value to medical researchers. They allow scientists to study the effects of drugs...
