Yes... I have reviewed this article and there were 4 monkeys involved (if I read it correctly). One was a control, one was treated with scaffold only and two were treated with scaffold laced with stem cells. The article's focus was to develop a methodology for allowing any sci treatment to be clinically evaluated in non-human primates.
Would hope that with the many follow-up studies done that the data/results would find its way into an article or two.
