This article describes the structure of ovine interdigital sinuses using scanning electron microscopy, highlighting features such as dense secretory material, hair presence, and classical apocrine secretion characteristics.

This study introduces a co-design framework using finite element analysis to optimize separable bubble microneedles, demonstrating enhanced transdermal and sublingual drug delivery in preclinical models. In vivo results showed faster hair regrowth and glucose lowering in animals, indicating potential improvements over traditional methods.

This study systematically characterized the nanomechanical properties of human hair, such as hardness and elastic modulus, across different ethnicities and treatment conditions using nanoindentation and scanning electron microscopy.

This review discusses recent advances in understanding the structural hierarchy of trichocyte keratins, including their heterodimeric structure and distinct conformations impacting hair growth, with no new experimental results reported.

This study found that the finer fibers of Alpas cashmere, compared to ordinary cashmere, are associated with the down-regulation of specific keratins and keratin-associated proteins, suggesting a molecular target for breeding cashmere goats with improved fiber quality.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

This study identified genes potentially involved in the development and differentiation of skin appendages in Atelerix albiventris, noting significant enrichment of immune-related genes in hair-type tissues.

This study found that low massage frequencies like 4.2 Hz enhance nanoparticle penetration into hair follicles more effectively than higher frequencies, indicating potential applications in therapeutic and cosmetic delivery.

This study demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.

This research identified key miRNAs involved in sheep fetal hair follicle development, highlighting the prolactin signaling pathway and platelet activation as critical processes in secondary follicle initiation.

This study found that human trichohyalin has a unique protein sequence potentially contributing to at least three important functions in hair follicle and epidermal cells.

In this study using C57BL/6 mice, researchers found that iron oxide nanoparticles permeated skin primarily through hair follicles and sebocytes, with absorption increasing over time.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

This article discusses the complexities in diagnosing hair shaft disorders and the potential insights hair microscopy can provide, without reporting new clinical findings.

This study explored the use of "microfollicles," a human hair follicle organoid model, as an in vitro tool for testing hair-growth substances, finding up to 75% overlap in gene expression changes with human clinical biopsy responses to minoxidil, indicating its potential for pre-clinical substance testing.

This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

This article reviews methods for examining the localization and activity of ROP GTPase, cortical microtubule organization, and F-actin dynamics in plant cell models, but reports no new experimental results.

This study identified a human sequence likely coding for a new ultra-high sulphur protein, which may aid in understanding hair differentiation and the molecular basis of human trichothiodystrophy.

This study found that PGRP-S expression in mouse epidermis is specific to certain hair follicle epithelia, depending on the skin region, and can be transiently induced in flank skin hair follicle epithelium after exposure to Staphylococcus aureus, suggesting a role in environmental surveillance.

This study reveals that the microRNA-200 family, highly enriched in hair matrix progenitors, restricts sebaceous gland development by inhibiting the SOX9-dependent lipogenic program, highlighting its specific role in epithelial plasticity within hair follicles.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

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.

In this study, upper-bulge epidermal stem cells in mouse hair follicles were shown to play a role in forming tactile sensory units by creating an extracellular matrix that supports nerve interactions.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

This study found that miR-133a-3p and miR-145-5p influenced goat hair follicle stem cell differentiation by inhibiting NANOG expression and promoting SOX9 expression.

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.

This study found that disrupting the microtubule cytoskeleton in Arabidopsis root hairs caused loss of growth directionality and suggested microtubules interact with calcium gradients to regulate apical growth stability.

Reflectance confocal microscopy can tell apart white dots on the scalp as either sweat gland ducts or hair follicle openings.
