Aminoguanidine Vascular Endothelial Growth Factor VEGF hair follicle micrografts outer root sheath cells bFGF IGF-1 AMG basic Fibroblast Growth Factor Insulin-like Growth Factor 1

Studysummary This study found that aminoguanidine induces VEGF mRNA expression in stored hair follicle micrografts and outer root sheath cells, suggesting potential for enhancing growth factor production during storage. Our plain-language summary of this paper — not a Tressless recommendation.

In 2005, researchers discovered that Aminoguanidine (AMG) could induce a dose-dependent increase in Vascular Endothelial Growth Factor (VEGF) mRNA in stored hair follicle micrografts from 10 patients, without affecting other growth factors like bFGF or IGF-1. This induction was particularly notable in outer root sheath cells, with a 14-fold increase in VEGF mRNA observed. The study suggested that AMG might improve the viability and post-transplant success of hair micrografts by influencing growth factor production during storage, although the clinical implications of these findings required further investigation.

research Expression of Vascular Endothelial Growth Factor, Apoptosis Inhibitors (Survivin and p16) and CCL27 in Alopecia Areata Before and After Diphencyprone Treatment: An Immunohistochemical Study

58 citations , May 2004 in “British Journal of Dermatology”

This study found that topical immunotherapy affects angiogenesis and immune cell ratios in the scalp, potentially offering insights into the mechanisms underlying alopecia areata.

research Mrp3, A Mitogen-Regulated Protein/Proliferin Gene Expressed In Wound Healing And In Hair Follicles

34 citations , May 2001 in “Endocrinology”

This study found that MRP3 is induced in wound edge keratinocytes during wound healing and may play a role as a growth or angiogenesis factor in this process and the hair follicle cycle.

research Control of Hair Growth and Follicle Size by VEGF-Mediated Angiogenesis

520 citations , February 2001 in “Journal of Clinical Investigation”

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

research Effects of Cooling Micrografts in Hair Transplantation Surgery

31 citations , September 1999 in “Dermatologic Surgery”

This study found that cooling hair grafts during transplantation did not significantly improve the survival or growth rates of hair follicles compared to room temperature storage.

research Analysis of Apoptotic Cell Death in Human Hair Follicles In Vivo and In Vitro

140 citations , December 1998 in “Journal of Investigative Dermatology”

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

research Growth Factors in Hair Organ Development and the Hair Growth Cycle

90 citations , October 1996 in “Dermatologic Clinics”

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

research A Comparison of the Culture and Growth of Dermal Papilla Cells from Hair Follicles from Non-Balding and Balding (Androgenetic Alopecia) Scalp

30 citations , March 1996 in “British Journal of Dermatology”

research Effect of Minoxidil Sulfate and Pinacidil on Single Potassium Channel Current in Cultured Human Outer Root Sheath Cells and Dermal Papilla Cells

16 citations , July 1994 in “Journal of Dermatological Science”

This study found that minoxidil sulfate and pinacidil did not activate K channel currents in hair follicles, suggesting their effect on hair growth might occur through other mechanisms like increased blood flow.
