Last time I looked, this technology was not functional yet it seemed like they were trying to commercialize it in the non-functional state by pretending it was a trial. The hangup involved the step between "we inject the cultured stem cells" and "those cells actually grow hair." Have they overcome this barrier? Or is this still a "trial" that a reasonably informed person would expect to have an infinitesimal chance of success wrapped in press releases that suggest a rosier picture?
