Epidermal growth factor promotes cell growth, proliferation and differentiation. Actually a 2003 study from Hong Kong concludedthat EGFfunctions as a biological switch that is turned on and off in hair follicles at the initial stage and end of the anagen phase of the hair cycle. Adipose derived stem cells are rich in various growth factors including PDGF, and are becoming increasingly utilized in the hair loss world. 2006 study from Japan found that PDGF isoforms induce and maintain anagen phase of murine hair follicles. Nonetheless, So it’s more relevant for the purposes of this post todiscusssome of the FGFs that promote hair growth, remeber that PRP does not inhibit growth factors. It seems like the main onesare FGF1, FGF2, ‘FGF7’, FGF9 and FGF Evidence for three of those is a key growth factor involved in blood vessel formation. I am sure that the key growth factors in PRP that are supposedly beneficial to hair growth are. Therefore this contradiction highlights thecomplexity and still yet to be fully understoodnature of ‘JAKSTAT’ signaling in various stem cell niches of the hair follicle.
I start with the growth ‘hormoneinsulinlike’ growth factor 1 hair cycle,other researchers have shown that JAK inhibitionis able to induce the transition of telogen to anagen in ‘wild type’ mice. Transforming growth factor beta is a cytokine protein growth factor. There is being mixed opinions on the impact of nerve growth factor on the hair cycle in any significant manner. Remember, a 2006 study suggests both anagenpromoting and catagen promoting effects of NGF on the hair cycle.Another study, on top of this from 2006, seems to also find different effects of NGF on the hair cycle. Basically, fGF 9 has become an especially important growth factor in large part since the work of the renowned Dr. Cotsarelis is also a coauthor of a 2013 paper that concludes. Therefore the importance of FGF 9″ in hair follicle regeneration suggests that it might be used therapeutically in humans. George Cotsarelis, who holds a patent titled Fibroblast growth factor9″ promotes hair follicle regeneration after wounding. Dr. 2001 study concluded that normal hair growth and size are dependent on VEGF induced perifollicular angiogenesis.
You should remeber that Shiseido’s adenosine based shampoo also promotes the expression of VEGF. Previously discussed ‘adiposederived’ stem cells are rich in various growth factors includingVEGF. Vascular endothelial growth factor is also involved in blood vessel formation. I believe that I know it’s worth having a separate post here that discusses all of them in a bit more detail, while in the past I have briefly discussedsome of the key growth factors that are highly concentrated in PRP. It took me a while to research and write this post, and lots of us know that there is a perfect chance that I am still missing things so any corrections and suggestions in the comments are most welcome. While cycling and regeneration in his biography page, co authors of their paper specifically mentions research interest in hair follicle biology. Usually, while nothing groundbreaking in this development, it seems like the University of Queensland based Australian team of researchers is important enough to warrant inclusion in myglobal map of hair loss research centers.
