Various Wavelengths of Light-Emitting Diode Light Regulate the Proliferation of Human Dermal Papilla Cells and Hair Follicles via Wnt/β-Catenin and the Extracellular Signal-Regulated Kinase Pathways

January 2017 in “ Annals of Dermatology ”

Hong Jin Joo, Kwan Ho Jeong, Jung Eun Kim, Hoon Kang

The study suggested that LED light had the potential to stimulate the proliferation of human dermal papilla cells (hDPC) by activating the Wnt/β-catenin signaling and ERK pathways. This was the first report to investigate the effects of various wavelengths of LED on hDPC proliferation and the underlying mechanisms.
