January 2011 in “Journal of Cutaneous Pathology” This study found that CK15 is an unreliable marker for assessing bulge zone integrity in cicatricial alopecia follicles due to its altered expression in diseased conditions.
May 2020 in “Archives of Medical Science” This study reports that androgenetic alopecia patients exhibit reduced CK15 and tropoelastin expression and increased cellular senescence markers, indicating tissue damage in affected hair follicles and surrounding structures.

December 2001 in “American Journal of Dermatopathology” This study found that trichoblastomas and nodular basal cell carcinomas have similar cytokeratin expression patterns, indicating differentiation towards the outer root sheath epithelium.

January 2009 in “British Journal of Dermatology” This study found that in scarring alopecia, stem cells are differentially localized, suggesting that both inner and outer root sheath stem cells, rather than just follicular bulge stem cells, are involved.

December 2015 in “International Journal of Dermatology” This study suggests that basal cell carcinoma and trichoblastoma may share differentiation toward the hair follicle, as indicated by strong positivity in CK 15, follistatin, and Bmi‐1 markers.
