For those who've lost their teeth to
accidents and decay, there may be a new way to restore them:
URINE.
Scientists in China have successfully
used cells found in human urine to regrow teeth.
Stem cells obtained from urine could
one day allow humans to regrow lost teeth, scientists claim.
Chinese scientists used stem cells
from urine to create tiny 'tooth buds' that when transplanted into mice grew
into tooth-like structures.
Stem cells — cells which can grow
into any type of tissue — are popular among researchers looking for ways to
grow new teeth to replace those lost with age and poor dental hygiene.
The group at the Guangzhou Institutes
of Biomedicine and Health used urine as the starting point, BBC News reported.
Cells which are normally passed from the body, such as those from the lining of
the body's waterworks, are harvested in the laboratory. These collected cells
are then coaxed into becoming stem cells.
