Well its about freaking time, and also how awesome. This is some healing technology if I ever heard of any. At least a lot of promise and potential in this area is welcomed right now. The amount of people who would be able to feel better with a medical approach through science to show how to make the ability to smile return in many lives. The scientists were able to make sure the lab rats are getting brand new shiny chompers, but this is still very early as we can assume and a lot more work is yet to be done.
The isolation of a 'gene-1', or USAG-1, and how it interacts with 'BMP' or 'Bone Morphogenetic Protein', or growth protetins, and 'Wnt'. The 'Wnt' signaling are pathway proteins that pass signals into a cell receptors. Here new medical innovation is again seen where by knowing exactly how to help our bodies achieve this is now seemingly coming into view.
One of the most relevant data points is how this new understanding of the genetic interaction with 'BMP' and 'Wnt', the application has protentional with many other organs and tissues to be hopefully regrow able. The future is bright indeed with revelatory stuff like this.
