Science with real bite: Full set of teeth grown in lab

from Mail Online

Scientists have grown fully formed teeth from stem cells. The artificial teeth looked like the real thing, were sensitive to pain and could chew food. The breakthrough was made on mice but could pave the way for those who lose teeth to decay or injury being able to "grow" replacements. The researchers harnessed the power of stem cells — "master cells" that have the potential to be used to grow any part of the body — to generate teeth. Two types of stem cell which between them contain all the instructions for making teeth were mixed together and grown in the lab in a mixture of chemicals and vitamins that started their transformation. After five days, they had formed a tiny tooth bud. The fledgling tooth was then placed in a tailor-made plastic box deep inside a mouse's body, where over the next 60 days it grew to form a full tooth. more
