Unexpected stem cell factories found inside teeth by Sarah C. P. Williams || 30 July 2014 || Science/AAAS | NewsDevelopment is typically thought to be a one-way street. Stem cells produce cells that mature into specific types, such as the neurons and glia that compose nervous systems, but the reverse isn’t supposed to happen.Yet researchers have now discovered nervous system cells transforming back into stem cells in a very surprising place: inside teeth. This unexpected source of stem cells potentially offers scientists a new starting point from which to grow human tissues for therapeutic or research purposes without using embryos.Continue reading … -- source link
