This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This study identified various cell types in the canine claw, showing complex mechanisms of cellular differentiation similar to mammalian hair and human nails.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This review examines the potential of K18 as a diagnostic and prognostic marker in epithelial-derived tumors, highlighting its specific expression in tumor tissues and interaction with proteins involved in tumor progression, without reporting new clinical findings.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This review examines histochemical and immunohistochemical markers to differentiate apocrine and eccrine sweat glands, highlighting their distinct markers, though it reports no new clinical findings.

This study suggests that intercellular communication via the WNT5A and STAT pathways may partly drive EMT-like phenomena in keloid pathogenesis, based on findings in an animal model.

This study reported that GFP labeling driven by the K15 promoter enables visualization and selection of stem cells in adult human scalp hair follicles for further analysis and manipulation.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

This study demonstrates that using a K15 promoter-driven GFP labeling technique allows for the identification and characterization of epithelial stem cells in adult human hair follicles.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This study found that Sox9 was variably expressed in most canine skin neoplasms, particularly in those originating from the hair follicle's bulge region, suggesting its potential as a stem cell marker.

This study found that the expression of CK 15 and CK 19 in vitiligo patients undergoing phototherapy was correlated with improved repigmentation, suggesting their potential as markers for stem cell stimulation.

Adult hair follicle cells can create new hair follicles from corneal cells with the right support.

This study found that Krox20 marks a diverse stem cell population in mouse hair follicles, which significantly contributes to the interfollicular epidermis and regulates epidermal homeostasis.

CD34 is a marker for isolating stem-like cells in mouse hair follicles.

This study suggests that Sox13, although dispensable for epidermal development, serves as a marker for early hair follicle development in Sox13-LacZ knock-in mice.

Krox20 is crucial for hair growth and maintaining skin stem cells.

Sox13 is a new marker for early hair follicle development and differentiation.

This study found that NGAL expression in embryonic skin is spatio-temporally regulated and strongly induced in adult skin conditions with dysregulated differentiation, suggesting a role in epithelial differentiation pathways.
