Dr. Kemp, Jarjar, Jamesbond, etc. have you seen this article in the journal Cell -
Nothing new there really, but it does indicate that better results (visible hair growth) were obtained by injecting a “combination of human adult cultured dermal papilla and epithelial cells.”
The article also indicates that this was new hair growth, as opposed to existing miniaturised follicles being enlarged.
As I’ve said before, I think the chances of enlarging existing, miniaturised follicles is probably very low, because only a tiny (perhaps insignificant) fraction of the injected cells ever make their way into the existing follicles. Therefore the only hopeful way of growing hairs in this way is by inducing de novo follicles to grow. The problem with that is, in order to grow brand new follicles, you have to get just the right combination of cells and everything else in place perfectly. Since you’re not relying on the pre-existing infrastructure of follicles that are already there, this will require more advanced tissue engineering than just the simple “injection of DP cells” that Aderans and Intercytex were doing.
That’s just speculation on my part. What do you think of this?
