April 2023 in “Journal of Investigative Dermatology” This study found that the dermal sheath smooth muscle regulates hair follicle progenitor cell death during hair regression through mechanical signaling of the TGF-β pathway.
January 2025 in “International Journal of Genomics” This study identified three hub genes—BMP4, POSTN, and WNT5A—that are closely associated with keloid fibroblast hyperplasia, suggesting they may serve as potential biomarkers for inhibiting this condition. Further research is necessary to fully understand their roles in keloid development.
