This review discusses the role of BMP/Wnt signaling in regulating stem cell homeostasis and activation but reports no new experimental findings.

This study found that the corneal epithelium differentiation program can proceed independently of lens formation, suggesting the corneal program is the default in eye development.

This study found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.

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.

The study observed that the tumor suppressor activity of bone morphogenetic proteins in mouse skin epithelium depends on Noggin levels, inhibiting Wnt and Shh signaling pathways to prevent tumor initiation and progression.

This study observed that heavy draft horses with verrucous pastern dermatitis showed significantly increased expression of keratins K6 and K16, suggesting a phylogenetically conserved keratin expression pattern in response to skin inflammation and proliferation.

This study found that cutaneous stem cells in the basal layer of fetal human skin contribute to the development of the epidermis and hair follicles, with specific marker expressions during different stages of skin development.

This study found that, while hair follicle bulge stem cells are important for hair follicle survival and epidermal regeneration after wounding, the epidermis maintains itself independently of these cells under normal conditions.

In this study, researchers at Johns Hopkins University found that Keratin 17 plays a signaling role in cell growth during a wound response by aiding mTOR pathway activation, beyond its structural functions.

This review discusses the roles of the hairless (HR) protein as a corepressor, particularly its impact on RORα-mediated transcriptional repression, and reports no new experimental findings.

This study established a method for selecting human hair follicle stem cells through quick-adherence to collagen, and found that β-catenin plays a role in their proliferation and differentiation.

This study found that selective adhesion to type IV collagen successfully enriched human hair follicle stem cells based on distinct adhesion properties and marker expressions.

This study found that residual sweat glands in hypertrophic scar tissues may regenerate from adult epidermal stem cells or residual glands after burn injury.

This study found that epidermal stem cells are located in rats' hair follicle bulge regions, and the methods used to isolate and culture these cells in vitro are feasible.

This study found that intradermal injection of specific oligonucleotides altered hair growth and morphology in mice by inducing a dominant mutation in the K17 gene.

In this study, the researchers reported that the expression of keratin 14 in the skin and hair follicles of neonatal and juvenile rats differs from that observed in adults or human embryos.

This study found that the distribution of hair keratin family proteins varies in normal scalp hair follicles, which may aid in identifying the origin of hair neoplasms.

This study found that human embryonic and induced pluripotent stem cells differentiated into specific bulge stem cells and successfully formed new hair follicles when transplanted with mouse dermal cells in immunodeficient mice.

This study found that keratin expression patterns vary within nail unit structures, with the nail matrix uniquely expressing the acidic hair-type keratin Ha1.

This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

This study found that the selective PPARγ modulator GMG-43AC may inhibit unwanted hair growth by inducing catagen phase while preserving hair follicle epithelial progenitor cells, suggesting potential in anti-hirsutism therapy.

This review discusses cornea-specific keratin expression patterns in human and mouse development and reports no new experimental results; it highlights the need for investigating keratin mutations' role in pathology.

This study found that the spermidine analog N1-methylspermidine prolonged hair follicle growth and decreased inflammation and oxidative stress in cultured hair follicles, suggesting potential relevance for treating inflammatory scalp diseases.

This study reports that actively proliferating Lgr5+ stem cells in hair follicles do not appear to drive tumor formation in experimental skin carcinogenesis.

In this study, constitutive expression of Del1 in mice did not affect wound healing but was associated with increased hair growth following anagen induction.

In this study, keratin genes mHa1 and mHb4 were unable to form an extensive keratin network in one cell line, altering endogenous keratin distribution, but showed better integration in another cell line.

This study suggests that onychopapilloma may originate from the nail bed rather than the nail matrix, with nail bed-related keratins and HK31 potentially serving as diagnostic markers.

This study aimed to enhance the skin penetration of minoxidil by encapsulating it in glycerosomal vesicles, offering a potential improvement in transdermal drug delivery for treating androgenetic alopecia. Results of the investigation were not reported.

This study evaluated a pumpkin seed oil hair gel formulated with various additives and found that the F3 formulation had promising physicochemical properties and non-irritant characteristics for potential use in treating androgenetic alopecia.
