This study found that the proteins Par3, mInsc, and Gαi3 cooperate to regulate LGN polarization and promote perpendicular cell divisions during murine epidermal morphogenesis.
November 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study used a novel fluorescent tagging method in mice to observe collagen IV dynamics during hair follicle development, revealing that alterations in basement membrane turnover can influence epithelial progenitor cell behavior and organ morphology by affecting cell proliferation and movement.

September 2016 in “PLoS ONE” The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

May 2013 in “Proceedings of the National Academy of Sciences of the United States of America” This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.
November 2025 in “Nature Communications” This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.
