Stem Cells from Teeth Make Mammary Tissue

Stem Cells from Teeth Make Mammary Tissue

Sometimes science stuns. It unnervingly reminds us of how little we know but also how much it could change the future, and for the better. A recent publication described how investigators isolated stem cells from adult mouse teeth and then transplanted these cells into mouse mammary fat tissue devoid of the highly specialized mammary epithelial cells that produce milk during late pregnancy and after birth. The stunning result was that mammary tissue was regenerated from the dental stem cells. Amazingly, the new mammary tissue contained cells that produced milk proteins during pregnancy and formed structures somewhat like mammary tissue ducts. The certainty of established scientific ideas about cell fate is now much more fluid. Read More...
