This study found that keratin 15 lacks the ability to sequester YAP1 in keratinocytes effectively, unlike keratin 14, and suggests that a higher K15:K14 ratio may promote a progenitor state and inhibit differentiation in epidermal keratinocytes.

This study demonstrates that α-parvin is crucial for epidermal morphogenesis and hair follicle development by mediating integrin-dependent adhesion and actin organization in keratinocytes.

This study found that the cytokeratin patterns in skin epithelia can distinguish between different types, with basal-cell epitheliomas showing a striking similarity to the pilosebaceous tract.

This study found that RXRα/RARγ heterodimers are necessary for retinoic acid-induced keratinocyte proliferation in the skin, while normal epidermal maintenance does not require RAR-mediated signaling.

This study proposes a model suggesting that the ratio of keratin 15 to keratin 14 in epidermal keratinocytes promotes a progenitor state and opposes differentiation, based on insights from both cell culture and transgenic mouse models.
