This study found that the proteins Par3, mInsc, and Gαi3 cooperate to regulate LGN polarization and promote perpendicular cell divisions during murine epidermal morphogenesis.

May 2021 in “Nature Communications” This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.
October 2021 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that mechanical disruption of the desmosomal cadherin Dsg3 in hair follicle stem cells activates them from quiescence, highlighting its role as a key regulator of stem cell quiescence and epithelial niche integrity.
April 2026 in “Development” This study found that loss of integrin-β4 or its ligand, laminin-α3β3ɣ2, in keratinocytes increases differentiation via delamination, and demonstrated a role for hemidesmosomes in epidermal differentiation through both mitotic and non-mitotic mechanisms, influenced by Notch signaling.

August 1998 in “FEBS Letters” In this study, researchers identified two novel peptidylarginine deiminases from treated rat keratinocytes, both showing enzyme activity with PAD‐R11 reflecting a characteristic of epidermal enzymes.
