Scientists created skin from stem cells and are planning to start a clinical trial in 2014.

Of course this is exciting news because of the close relation to hair grafts. Remember how Jahoda said that the main remaining issue was to figure out how to increase gene expression by creating the right environment (so tricking the cells into thinking they're in the body). The researchers in this study solved that problem: "In this work we have studied the capability of HWJSCs to differentiate in vitro and in vivo to oral mucosa and skin epithelial cells using a bioactive three-dimensional model that mimics the native epithelial-mesenchymal interaction. To achieve this, primary cell cultures of HWJSCs, oral mucosa, and skin fibroblasts were obtained in order to generate a three-dimensional heterotypical model of artificial oral mucosa and skin based on fibrin-agarose biomaterials."
This is of course pretty much what Jahoda is trying to figure out. Hopefully this milesone this will be useful in the race for the first artificial human hair transplant. And either way, clinical trials starting with this in the upcoming year, that's quite exciting and this has to be good for the hair regeneration quest too.
*EDIT* more about this fibrin-agarose biomaterial used (it was developed a few years ago by the same scientists) : http://www.sciencedirect.com/science...51616111001718
