TLDR The BMP/Smads pathway and Id2 gene control hair follicle stem cells, affecting their rest and growth phases.
The document detailed a study on the role of Smads and Id2 genes in hair follicle stem cells (hfSCs) regulation. Using an inducible Bmprla transgenic system and ChipSeq analysis, researchers found that 72% of genes affected by BMP ablation in hfSCs were directly regulated by the BMP/Smads pathway. The study confirmed that the Id2 gene is a direct target of BMP signaling and that its overexpression in hfSCs leads to a prolonged resting phase and delayed hair growth phase, keeping stem cells in a dormant state. This research highlighted the importance of the BMP/Smads pathway and the Id2 gene in the maintenance of hfSCs.
