What triggers the cessation of cell growth during regeneration? Has regeneration ever surpassed expected optimal growth?

Mesenchymal stem cells will stop proliferating when they physically contact each other (otherwise known in cell culture lingo as “confluence”). Culturing these cells, it becomes obvious that once they reach that point, they refuse to continue to grow (proliferate). This is because they are repair cells and when an area in need of repair is fully covered, they get the signal to stop growing. In the appr0ximately 60 patients where we have ongoing MRI surveillance of the re-implant sites, there has been no evidence of overgrowth where the regeneration has surpassed “expected optimal growth”.
