TLDR There are two types of stem cells in rodent hair follicles, each with different keratin proteins.
The study identified two distinct populations of skin epithelial stem cells in the vibrissa hair bulge, differentiated by their keratin profiles. This discovery provided insights into the complexity of stem cell niches in hair follicles and their potential roles in hair growth and skin regeneration. The research highlighted the role of specific keratins in cellular processes and the potential of outer root sheath cells to regenerate epidermis and contribute to hair follicle formation.
