Nature covers an article in Nature Methods that describes how researchers were able to create new brain cells starting only with discarded cells flushed away in urine. This is terrific news for a variety of reasons, starting with the fact that this stem cell treatment doesn’t require destroying human life. In addition, stem cells derived from embryos tend to be hard to control, but the brain cells cultured this way–when implanted into rats–didn’t lead to any tumors. It also helps that these cells are obviously easier to harvest (“We work on childhood disorders,” said one of the researchers. “And it’s easier to get a child to give a urine sample than to prick them for blood.”) Finally: this allows researchers to create stem cells for a patient from that patient’s own cells.
Sometimes, the future is rad.
