Human teeth to be grown from urine


Human teeth could one day be grown from urine, say scientists.

Stem cells derived from waste matter have been used to create tooth-like structures in mice.

The method would use a patient’s own cells, decreasing the chances of rejection.

It would also avoid the controversial use of embryos.

However, it currently has only a 30 per cent success rate, said Chinese researchers.

And Professor Chris Mason, a stem cell scientist at University College London, told the BBC using urine was not the best place to start when harvesting cells.

‘It is probably one of the worst sources, there are very few cells in the first place and the efficiency of turning them into stem cells is very low,’ he said.

‘You just wouldn’t do it in this way.’

Prof Mason told BBC News the risk of contamination would be much higher using urine than it would be with other sources.
