LONDON - Stem cells obtained from urine could allow us to regrow lost teeth, according to scientists. In mice, a new system of tissue culture has allowed researchers to grow the cells into tiny structures resembling teeth, and they hope one day the technology could permit them to build the real thing in human patients. The stem cells are generated from urine, based on previous studies which have shown discarded cells in human waste can be coaxed into becoming pluripotent stem cells (iPSCs). These can then themselves generate many different cell types, including neurons and heart muscle cells, the Daily Telegraph reported. But researchers had yet to generate solid organs or tissues from iPSCs - until now, reported Cell Regeneration Journal. Dr Duanqing Pei, of the Chinese Academy of Sciences, created the tooth-like structures by forcing iPSCs to mimic two different cell typ...
