September 2006 in “Journal of Cutaneous Pathology” This study found that the p63 transcription factor is expressed during rat epidermal development and may serve as a specific marker for keratinocyte progenitor cells.
December 2025 in “The Journal of Cell Biology” 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.

March 2017 in “Development” This study found that specialized nipple epidermis in mice is maintained by the repression of TGFβ signaling through estrogen, which highlights the role of hormonal regulation in epidermal maintenance.
