July 2002 in “Molecular and cellular biology” This study found that overexpressing Dsg3 in the suprabasal epidermis of transgenic mice resulted in flaking skin and abnormal hair growth, supporting Dsg3's role in regulating epidermal differentiation.

March 1993 in “Journal of Cell Science” In this study, rabbit esophageal epithelial cells were found to produce K4 and K13 keratins in suprabasal cells, forming disulfide-crosslinked dimers that may support the physical stability of the esophageal lining.

July 2006 in “British Journal of Dermatology” This study found that keratin K17 is induced in the suprabasal layer of psoriatic scalp epidermis during epidermal hyperproliferation, suggesting it is not specific to hair follicles.
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.
April 2024 in “The journal of investigative dermatology/Journal of investigative dermatology” In this mouse model study, researchers found that deleting the ASH2L gene in epidermal progenitor cells led to thinner epidermal layers, delayed hair follicle development, and reduced epidermal stem cell pools, with alterations in genes related to hair follicle development and the Notch signaling pathway.
