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

This study found that somatosensory axons innervating Merkel cells in adult mouse skin exhibit significant plasticity, influenced by epithelial and neural factors, indicating a complex interaction in maintaining homeostasis.

This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.

In this study, researchers observed a high degree of plasticity in somatosensory axons innervating Merkel cells in adult mouse skin, revealing that both epithelial-neural crosstalk and intrinsic neural mechanisms contribute to axonal patterning and remodeling during epithelial homeostasis.

This study observed that Merkel cells and their associated somatosensory axons in mouse skin exhibit significant plasticity, remodeling dynamically to maintain homeostasis. Axonal branching patterns were notably influenced by Merkel cells, suggesting epithelial-neural interactions play a key role in axonal plasticity and patterning.

In this study, highly dynamic remodeling was observed in mouse somatosensory axons and Merkel cells, indicating that epithelial-neural interactions help maintain homeostatic remodeling, with additional intrinsic neural mechanisms contributing to axonal plasticity.

In this study, researchers identified the ventral matrix as the primary source of nail plate formation, while the dorsal portion is generated by the apical matrix.

This study reported that patients with alopecia areata have reduced expression of the melanocortin receptor MC2R in their scalp tissues compared to normal scalp, indicating potential involvement in the condition's pathophysiology.

In this ex vivo study, inhibiting Ezh2 with a small molecule slowed human hair growth by decreasing proliferation and increasing apoptosis in the outer root sheath.

This research observed that removing RNase L in mice enhances regenerative capacity through increased IL-36 and wound-induced hair neogenesis, highlighting RNase L as a gene that represses regeneration by moderating immune responses during viral infections.

The study concluded that all parts of the normal human Meibomian gland ductal system show signs of early keratinisation, supporting the idea that these glands are akin to "hair follicles without a hair shaft.

This paper details the early stages of human scar regeneration using topical iodine and examines hair's role in the regeneration process, noting hair's ability to move freely and transport regenerative material.

In this study, researchers reported that a keratinocyte growth factor-Ig fusion protein could specifically detect and localize KGFRs in epithelial tissues, suggesting a method for histochemical detection of growth factor receptors.

This study found that new rabbit antisera against recombinant mouse involucrin effectively marked keratinocyte differentiation, with comparable expression patterns to human involucrin.

This study observed that retinoic acid biosynthesis and signaling in hair follicles have a spatial and temporal regulation linked to distinct stages of the hair cycle in mice.

Stem cells in mouse nails are found in the nail matrix and may control nail growth.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

This study found that a bulge stem cell-enriched population from canine hair follicles successfully formed interfollicular epidermis in vitro within two weeks, suggesting potential for regenerative canine skin therapies.

This study found that hHbl gene expression is localized in the cortical cells of the human hair shaft and is notably high in pilomatricoma cells transitioning to hair shaft keratinocytes.

The researchers reported that autophagy, a lysosome-dependent degradation mechanism, plays a significant role in the cellular remodeling of keratinocyte differentiation in the skin, affecting the properties of the differentiation products by altering cellular components during this process.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This study demonstrated that plucked human hair follicles cultured in a collagen gel matrix developed spike-like structures, suggesting a useful method to study outer root sheath cell growth and differentiation in vitro.

In this study, researchers found that the expression of vimentin, desmin, and laminin in rat skin contributes to cell structure and tissue integrity, with varying reactions across different cell types.

This case report provides the first evidence of clinical and histopathological findings of cutaneous diffuse basaloid follicular hamartomas in a young domestic short hair cat.

This review discusses factors and disorders affecting healthy hair growth and loss but reports no new clinical results.

This study found that the expression levels of Siah1 and Siah2 in mice skin vary dynamically during postnatal hair follicle development, suggesting their specific roles in modulating the HIF pathway.

New findings suggest targeting IL-23 could treat psoriasis, skin cells can adapt to new roles, direct conversion of skin cells to blood cells may aid cell therapy, removing certain tumor cells could boost cancer immunotherapy, and melanoma may have many tumorigenic cells, not just cancer stem cells.

This study suggests that basonuclin in keratinocytes is likely a regulatory molecule linked to maintaining proliferative capacity and preventing terminal differentiation rather than a cell cycle marker.

This study found that hemoglobin α is upregulated in epidermal keratinocytes after UV exposure and may function as an antioxidant, particularly for hair follicle stem cells.
