Thymosin beta 4 - activation of hair stem cells

[level]

To my knowledge, Dr. Cooley did not begin working with ACell and plucking until 2009/2010, and he did present those results late in 2010. The work he's done since should be shared later this year (2011). Dr. Bernstein didn't begin his research with the compound until, I believe, just mid 2011; of course, we can't expect a "flood" of data or pictures just a couple of months into a study.

I hope I don't come off trying to defend the merits of ACell — I don't know whether there are any. It seems to me, however, this still is a "new" product, and I thus am reservedly hopeful it can be beneficial in treating hairloss. As for straight injections of P.R.P., there's a lot less I have to be enthusiastic about. For one thing, yes, the idea has been around longer, and I don't see any positive results from it. For another, I feel it requires less experimentation: ACell is supposed to work in conjunction with surgery, and figuring out how best to administer it might require a fair amount of effort and creativity. With P.R.P. on its own, however, one more simply must work out dosing; after that, it's direct shots into the scalp, then checking for growth.

I suppose by the end of 2011, though, we all should have a stronger sense to where we ought to set our hopes.

I agree-the verdict should be out on Acell by the end of the year. However, enough time has passed for there to be some visual evidence and frankly, I haven't seen any. Like you mentioned, Dr. Cooley starting experimenting with Acell towards the end of 2009 (2+ years). Also, several doctors have been offering PRP/Acell injections, claiming that it helps retain hair and thickens miniaturized hairs. As far as injecting a combination of Acell and PRP onto the scalp for the purpose of retaining hair and increasing density, there should be some evidence that we could point at and say: Aha, this is working! But there is none; not one pic that has me feeling even the slightest bit optimistic.

Perhaps Acell will be beneficial in healing the wounds created during a hair transplant. In that sense, it would be good. I just don't see anything that leads me to believe that it will increase density or that it is a "fertilizer," of sorts, for transplanted hairs. Maybe they just need time to tweak it all. I hope that's the case. Till then, I'll keep spectating.
