Researchers grow teeth from gum cells
The BBC reports on research by a team from King’s College London in which cells from adult gum tissue were combined with another type of cell from mice to grow a tooth. The leader of the study, Professor Paul Sharpe, said he hoped the technology could one day replace current dental implants. Professor Alastair Sloan, an expert in bone biology and tissue engineering at Cardiff University said the work was significant but there remained many hurdles before it would be available to patients.
