    Abstract

    Different Immortalized Keratinocyte Cell Lines Display Distinct Capabilities to Differentiate and Reconstitute an Epidermis In Vitro

    Researchers validated different engineered immortalized cell lines created from primary human keratinocytes as model systems to study epidermal function.

    Epigenetic Switch Reshapes Epithelial Progenitor Cell Signatures and Drives Inflammatory Pathogenesis in Hidradenitis Suppurativa

    The authors investigated hidradenitis suppurativa epithelial cells and demonstrated that hidradenitis suppurativa basal progenitors modulated their lineage restriction and gave rise to pathogenic keratinocyte clones, resulting in epidermal hyperproliferation and dysregulated inflammation.
