This study found that centrosome ablation in developing epidermis triggers cell surveillance pathways, resulting in thinner skin and halted hair follicle growth, while later stages of epidermal growth may operate independently of basal progenitor division orientation.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

This study found that stabilized beta-catenin is crucial for activating stem cell transition from quiescence to proliferation in hair follicles by influencing gene expression within the stem cell niche.

This review discusses the role of stem cell heterogeneity and compartmentalization within the epidermis and highlights their significance as niches for neighboring cells, without reporting new experimental results.
