February 2026 in “Nature Communications” This study combined spatial and single-cell transcriptomics to identify that hypercontractility of the connective tissue sheath activates PIEZO1 in hair follicles, leading to miniaturization in male androgenetic alopecia, and found that inhibiting this contraction improves hair growth in models.
December 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that targeting connective tissue sheath contraction with an MLCK inhibitor may improve hair growth in androgenetic alopecia by reducing premature hair regression caused by ectopic apoptosis of hair follicle progenitor cells.
In this study on Drosophila embryos, researchers observed that the Slit/Robo signaling pathway is crucial for the collective migration and proper positioning of Posterior Signaling Center cells within the hematopoietic niche, highlighting its role in niche assembly and cellular organization.
