This study examined the expression patterns of various cytokeratins in the outer root sheath of human anagen hair follicles, noting distinct differentiation patterns and localization of keratin markers.

This study reports promising preliminary results for using monoclonal antibodies to identify cashmere fibers, highlighting observed immunological differences from wool keratins.

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

The researchers reported that BCE-like changes overlying dermatofibroma show a differentiation pattern most similar to normal basal cells based on specific keratin markers.

This study reports that the monoclonal antibody BKN-1 specifically stained basal cell epithelioma cells and certain normal skin structures, indicating a similarity in keratin expression between the tumor and follicular epithelium below the isthmus portion.

This study found that hair germ and epidermal basal cells differ in keratin expressions in rat hair tissues, with hair-specific keratins appearing after the differentiation of each layer.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study found that solid basal cell epitheliomas and the outer root sheath of human hair follicles display nearly identical cytokeratin profiles, suggesting a potential origin connection.

In this study, hyperplastic layers of scabietic sheep skin showed expansive keratin labeling, indicating altered keratin expression compared to healthy skin.

This study demonstrated that keratin K124 is specific to equine hoof lamellar tissue and established monoclonal antibodies that can specifically recognize K124 without cross-reacting with other tissues.

The study examined cytokeratin expression in different bovine epithelial tissues, finding that hair follicles and nasolabial glands express both acidic and basic types, while other epithelia express only one type.

This study found that individuals with alopecia areata had significantly higher serum levels of retinol-binding protein 4 and increased IgG immunoreactivity against it, suggesting a role in the disease's pathogenesis.

This study found that mice lacking the CXCR2 receptor regenerated tissue scarlessly in various injury models and that administering plasma or G-CSF from these mice to wild-type mice also reduced scarring, suggesting potential therapeutic strategies to improve human skin wound healing.

In this study, rheumatoid arthritis patients showed no changes in the number of circulating follicular helper T cells, but these cells had increased CD200 expression, implicating them in disease pathogenesis and suggesting CD200/CD200R as a potential therapeutic target.

This study found that human hair follicle bulge stem cells exhibited autofluorescence, potentially due to high flavin- and NAD-related compound levels, highlighting the need to consider this when using fluorescent antibodies for studying these cells.

Basal cell carcinoma shows keratin patterns similar to undifferentiated hair follicle cells.

This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

In this study, melatonin administration enhanced various cellular and structural features of the scrotal skin in Soay rams, including increased thickness, cell count, and gland activity.

This study found that the patch assay effectively reconstituted mature hair follicles using culture-expanded human fetal cells and may serve as a method to assess cell trichogenicity.

This study found that partial follicular units extracted from the donor area can survive and regenerate new hairs at their original site and when transplanted, effectively creating two hair follicles from one.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This study found that implanting hair-follicle-associated pluripotent stem cell sheets facilitated wound healing and early macrophage activity while reducing inflammation in a diabetic mouse model, suggesting clinical potential for difficult-to-heal diabetic ulcers.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study found that laminin-511 is crucial for hair morphogenesis in mice, as it influences primary cilia formation and dermal papilla maintenance through noggin and sonic hedgehog signaling.

In this study, co-grafting human keratinocytes with murine dermal papilla-enriched cells produced hair follicle-like structures, but without regular hair formation, suggesting anomalous folliculogenesis.
