The Study of the Altering of Cytokines and Growth Factors Secreted by Cultured Balding Dermal Papilla Cells
January 2012
Studysummary This study found that neurotrophins produced by balding dermal papilla cells inhibited both their proliferation and hair follicle growth in vitro, suggesting a potential role in androgenetic alopecia. Our plain-language summary of this paper — not a Tressless recommendation.
The study investigated the role of neurotrophins (NTs) in androgenetic alopecia (AGA) by examining their effects on cultured balding dermal papilla (DP) cells and hair follicle growth. It was found that NTs, specifically brain-derived nerve factor (BDNF), neurotrophin (NT)-3, and beta-nerve growth factor (NGF), were upregulated in balding DP cells compared to nonbalding ones. These NTs inhibited the proliferation of DP cells and hair follicle growth in vitro, suggesting their involvement in the pathogenesis of AGA. The study also tested the potential of NTs neutralizing antibodies to reverse these effects, but they were largely ineffective, although a reversible trend was observed. This research highlighted NTs as key factors in the development of genetic hair thinning.
