September 2013 in “Bioscience Biotechnology and Biochemistry” In this study, the type II subunit of porcine hair keratin was found to significantly inhibit the differentiation of PC12 neural cells compared to the crude extract and type I subunit, although cell proliferation was unaffected.
August 2026 in “Mendeley Data” In this study, researchers explored how hair follicle neural crest stem cell-derived exosomes, particularly those carrying miR-214-3p, promote neurite outgrowth and aid peripheral nerve regeneration, supported by detailed in vitro and in vivo data on nerve repair and functional recovery in rat models.
May 2026 in “International Journal of Molecular Sciences” In this study, a new formulation of human placental extract showed antioxidant and neurite outgrowth activities, significantly reduced hair graying in mice, and alleviated neuropathy symptoms, suggesting potential therapeutic benefits.
