August 1998 in “The Journal of Cell Biology” In a transgenic mouse model, this study found that overexpression of keratin 16 in skin keratinocytes led to hyperkeratosis and increased EGF receptor signaling, altering skin cell behavior and structure.
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.

September 2017 in “Cancer Research” This study reports that hair follicles can mobilize ectopic progenitors for regeneration to repair damage from ionizing radiation. Augmenting WNT signaling enhanced this regenerative process and prevented radiation- and chemotherapy-induced hair loss, highlighting a potential approach to manage alopecia during cancer treatment.
This research reports that after genotoxic stress from ionizing radiation or chemotherapy, hair follicles can utilize progenitor cells from transit-amplifying compartments, not quiescent stem cells, for repair, suggesting a potential therapeutic approach to prevent therapy-induced hair loss by activating these progenitors.
This study suggests that targeting the activation of transit-amplifying cell-derived progenitor cells may help prevent hair loss from chemotherapy and radiotherapy by promoting hair follicle regeneration.
In this study, various cellular responses and signaling pathways were examined in hair follicles after exposure to ionizing radiation, including the effects of Wnt3a treatment, with findings noted in apoptosis, DNA damage, and differentiation processes.
Results are not reported in this study, which investigated the effects of radiation on hair follicles and evaluated various cellular responses and signaling pathways, particularly focusing on WNT signaling and the impact of Wnt3a treatment.
