April 2023 in “Journal of Investigative Dermatology” This study found that inhibiting PI3 kinase in epidermal stem cells reduces YBX1 phosphorylation, thereby decreasing cellular senescence and enhancing wound healing and regeneration in adult-derived skin models.
In this study, researchers observed that oncogenic HrasG12V in single murine epidermal cells leads to an initial increase in progenitor cell renewal, but ultimately results in balanced cell fate choices that limit clone growth.

October 2016 in “Stem Cells and Development” This study found that epidermal growth factor significantly enhances the proliferation of hair follicle-derived mesenchymal stem cells through the EGFR/ERK and AKT pathways, without involving the STAT3 pathway.
November 2020 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that the Polycomb Repressive Complex 2, particularly its component Ezh2, is crucial in regulating dermal fibroblast differentiation and epidermal keratinocyte proliferation during murine skin development.
November 2022 in “Journal of Investigative Dermatology” This study reported that an HS-associated NCSTN mutation in iPSC-derived skin organoids led to altered hair follicle stem cell differentiation and increased expression of proteins linked to HS inflammation.
