Studysummary This study found that when NFIB was removed in adult mouse hair follicle stem cells, it did not affect their maintenance but unexpectedly led to increased proliferation and differentiation of nearby melanocyte stem cells.

The study explores the coordination between epithelial hair follicle stem cells (HFSCs) and melanocyte stem cells (McSCs) in hair follicles, focusing on the role of the transcription factor NFIB. While NFIB is crucial for hair follicle morphogenesis and wound repair, its ablation in adult HFSCs does not affect their maintenance or the hair cycle. Surprisingly, NFIB loss in HFSCs enhances the proliferation and differentiation of nearby McSCs. These findings highlight the complex interplay between HFSCs and McSCs and suggest that their cooperative behavior can be disrupted in conditions like injury, stress, and disease.
