In this study, researchers documented the immunohistochemical distribution of CD34 in basal cell carcinoma and found distinct patterns of CD34 expression, with variations in CD34 positivity between different areas of BCC tumor stroma and adjacent skin regions.

Keratins 8 and 14 can help identify and diagnose benign skin tumors.

This study found that CD34 is necessary for TPA-induced activation of hair follicle stem cells and tumor formation in mice, with CD34 knockout mice showing delayed and reduced tumor development compared to wild-types.

This study found that basal cell carcinoma exhibits altered expression patterns of CD10, p63, BCL-2, and EMA proteins compared to normal skin, with notable differences in staining and reactivity.

CD10 helps distinguish between basal cell carcinoma and benign hair follicle tumors.

This study indicates that CD4 protein may have a functional role in basal cell-like keratinocytes through TCR/CD3-independent signaling, affecting their proliferation, differentiation, and migration.

This study suggests that PDCD4 regulates keratinocyte proliferation and contact inhibition, playing a role in epidermal homeostasis and wound healing.

This study reported that K14 expression patterns and keratin filament organization in human skin's hair follicles differ from those in the epidermis, indicating distinct differentiation programs.

This study proposes a model suggesting that the ratio of keratin 15 to keratin 14 in epidermal keratinocytes promotes a progenitor state and opposes differentiation, based on insights from both cell culture and transgenic mouse models.

This study found that canine hair follicle stem cells in vitro expressed markers associated with multipotency, suggesting their potential role in the hair cycle.

This study observed that cytokeratin 19 expression in cutaneous carcinomas correlates with the grade of squamous cell carcinomas, with more expression in higher-grade SCCs.

This study reports that caspase-14's expression pattern in the epidermis and hair follicles is highly conserved across diverse mammalian species, suggesting its early evolutionary role in mammalian skin maturation.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

In this study, researchers reported that CD34 expression in the isthmic region of canine hair follicles suggests a potential stem cell compartment in this area.

This study observed two distinct groups of alopecia areata lesions based on PD-1 expression in T cells from biopsied skin samples, suggesting potential differences in subtypes or stages of the disease that warrant further investigation.

This study suggests that the presence and arrangement of plasmacytoid dendritic cells can help distinguish chronic cutaneous lupus erythematosus from other types of scarring alopecia.

This study identified a radio-resistant population of Krt15+ stem cells in the mouse small intestine that can initiate tumors, suggesting potential targets for colon cancer therapy.

This study found that in biopsied skin samples of alopecia areata, a lower anagen/telogen ratio was associated with increased T cell infiltration, and enhancing the PD-1/PD-L1 axis may inhibit CD8+T cell infiltration and improve the condition.

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.

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

This comprehensive review suggests that CD44 signaling plays a significant role in post-natal skin wound healing and scar formation, with potential for therapeutic approaches targeting CD44 to shift from fibrotic scarring towards regenerative healing, including wound regeneration and hair neogenesis.

This study found that CD1d is strongly expressed in human scalp skin and hair follicles, particularly in the anagen phase, suggesting a role in scalp immunology and potential implications for hair disorder treatment.

This article discusses the evaluation of minimal residual disease in childhood acute lymphoblastic leukemia using molecular methods and reports no new findings.

This study found that the expression of CD117 and platelet-derived growth factor receptor α differs in alopecia areata tissue compared to normal controls, with platelet-derived growth factor receptor α correlating with disease severity.

This study reports that a clinical prognostic model based on immune-related genes improved survival prediction for patients with clear cell renal cell carcinoma, also identifying potential drugs targeting the gene DOCK8.

This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

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.

This study found significant upregulation of IDO-1 and IDO-2 in human basal cell carcinomas, suggesting that IDO production may confer immune privilege characteristics to the tumors, potentially impacting their growth.
