Mucosal Tissue developed using Stem Cells then grafted
"What we do is to take a little biopsy of 0.5 cm from the place the vagina should be, " Marchese said. They used an enzyme to break down the tissue and then let the immature cells, called stem cells, generate new, mucosal tissue on their own. It took about 15 days to get a thick enough layer to transplant into the patients, Marchese said. http://www.reuters.com/article/scienceNews/idUSL3069953820070530?pageNumber=2

Informative article TT thanks for the link. Seems another approach to tissue engineering having some success and in an area with a complex function and form.

would be so nice if a company would try a product like this on the nose...
