Scientists have successfully grown functional hair follicles in a laboratory setting that naturally cycle through growth periods. This advancement, achieved in mice, identified a crucial third cell type supporting regeneration and tissue attachment.
The research defines a core three-cell combination required for a fully functional hair follicle. Previous lab-grown follicles lacked the ability to grow or connect to tissue without transplantation.
This breakthrough could pave the way for new treatments to restore follicle growth where it has ceased naturally. Beyond hair regeneration, the principles may inform the development of other lab-grown organs.
