New teeth grown from urine
Scientists in China have grown rudimentary from stem cells extracted from urine, according to a BBC report.
The Guangzhou-based scientists used urine as a source of cells they coaxed into becoming stem cells.
They mixed these cells with the connective tissues cells of laboratory mice, and implanted the concoction into the outer layer of the kidney of a mouse.
After three weeks, the cells developed into tooth-like structures.
The team, which published its results in Cell Regeneration Journal, hopes a revised version of the technique could be eventually be used to replace lost teeth.
A British stem scientist cited by the BBC was cautious regarding the results of the study, calling urine an inefficient source of stem cells.
