This study observed that innervation of the mystacial pad in rats by fine-caliber axons is more extensive and complex than previously described, with distinct differences in labeling patterns depending on the tracer and survival time.

In this study, researchers using live mice observed that oncogenic Kras mutation disrupts hair follicle architecture by sustaining ERK signal activation, which affects stem cell behavior and tissue integrity.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This article reviews the characteristics and therapeutic potential of neural crest cells from various sources, including embryonic and mature stem cells, but reports no new experimental results.

The hair follicle's connective tissue is a key source of a certain collagen in human scalp skin.

This study found that multi-hair follicles naturally orient perpendicular to the radial line from the crown whirl, suggesting that perpendicular transplantation of grafts could replicate this natural appearance.

This study found that in mice, competition for hair follicles guides the organization of follicle-innervating LTMR neurons during early development, with different neuronal subtypes showing varying adaptive responses to increased neuron populations.

This study observed that human primary adult hair matrix keratinocytes may have the potential to generate hair follicle organoids, suggesting possible applications in hair follicle neogenesis and preclinical hair growth agent screening.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This article reviews different perspectives on nevus comedonicus, discussing its classification and potential associations with systemic findings, but it reports no new results.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.

This study examined the formation of acquired curved hair and found that the fusion of hair matrix cells during follicle regeneration contributes to asymmetric follicle shapes and curved hair, potentially linked to changes in type IV collagen and protein expression levels.

This study observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

This study introduced a tabletop optical microscopy technique to measure the biomagnetic field reach of human hair follicles using Prussian Blue Stain with iron particles.

This study demonstrates that bulge KSCs from hair follicles can transdifferentiate into corneal epithelial-like cells under specific conditions, which could support bioengineered cornea development.

This study observed that the thinning and structural abnormalities in monilethrix-affected hair occur at the internodes due to possible periodic dysfunction of the hair matrix, particularly in the cortex.

The study characterized the transcriptional changes in porcine SKP cells transitioning to fibroblast-like cells, indicating potential roles for specific signaling pathways in this cell fate transition.

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.

This case report describes a pilomatricoma in a 21-year-old woman, highlighting the diagnostic process and illustrating the potential for intraoral surgical access to minimize scarring.

In this study, researchers demonstrated that follicular tight junctions in porcine skin form a barrier to nanoparticle penetration, particularly in upper regions, which supports its use as a model for human skin.

In this study, researchers observed that intractable pruritus in anterior chest keloid lesions is linked to increased intraepidermal nerve fibre density and elevated expression of substance P, without differences in Langerhans cells across different keloid regions.

This review describes the edge out punch for follicular unit excision, which may reduce follicle transection with its thicker walls and internal bevel design compared to other punch shapes, but reports no new clinical results.

The authors present a case of punctate follicular porokeratosis, suggesting it as a distinct clinical entity distinguished by keratotic lesions originating specifically from hair follicles.

This study reported that the concept of the onychodermis, defined by CD10 expression, is present in the developing nail organ and may play a role in nail plate formation.

This study developed a 3D engineered hair follicle model that mimics the native hair bulb and may aid in drug screening for hair growth therapies.

This study found that matrix progenitor cells in hair follicles move in a conveyor-belt-like fashion along the dermal papilla, changing their transcriptional states and lineage potential as they differentiate into inner hair follicle layers.

This study found that hair follicle-specific keratins can form different structural assemblies depending on ionic conditions, with hair cortex keratins requiring physiological salt conditions to form intermediate filaments.
