This study observed that in mouse fetuses, reticular contraction by actomyosin is involved in dermal regeneration, and differences in actin and α-SMA localization may determine the switch between regeneration and scar formation, suggesting potential insights for wound regeneration therapy.

This study observed that the glassy layer of hair follicles in guinea pigs consists of thick collagen-type fibrils organized into two distinct arrays, whereas in young mice, the fibrils are thinner and develop between the outer root sheath and fibroblasts.

This study found that human dermal papilla cells are embedded in a basement membrane-like extracellular matrix, which is essential for their aggregation and function, as supported by evidence that Matrigel enhances dermal papilla cohesion and gene expression compared to collagen I, which promotes cell dispersion.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

This study found that gelatin–polycaprolactone/silk fibroin composite membranes with line micropatterns enhanced wound healing in rats by promoting cell alignment, angiogenesis, and increased α-SMA production.

This study suggests that the cell membrane complex in hair cuticles contains hydrophilic regions with disulfide bonds allowing polymer uptake and hydrophobic lamella-like lipid layers.

Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

Oxidized trichocyte keratin has a helical dislocation in its structure.

This study found that fibronectin nanofiber dressings, made using rotary jet spinning, accelerated wound healing and improved tissue restoration in a full-thickness wound mouse model.

In this study, researchers found that changes in the extracellular matrix components, particularly fibronectin, laminin, and type IV collagen, during the rat vibrissa follicle growth cycle, suggest dynamic remodeling related to dermal-epidermal signaling.

In this study, electron microscopy of follicular mucinosis showed severe cytoplasmic degeneration in hair follicles, with myelin figures and onion-like lamellar structures, but no indications of mucin release through degeneration or degradation were found.

This study reports new cellular features and complex interaction systems in fiber differentiation, indicating more intricate cellular organization than previously recognized, including features like mast cells and primary cilia.

This study reports that expressed mouse type Ia and type IIa trichocyte keratins were successfully assembled into intermediate filaments in vitro, while also suggesting that disulfide bond cross linking enhances their stability.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

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 found that methylene blue staining may reveal anatomical details of intraepidermal nerve fibre endings in the rat mystacial pad with greater clarity than the zinc iodide-osmium tetroxide technique.

This study found that elastic fibre arrangements in the skin of domesticated mammals vary with hair density, with densely-haired species having horizontal fibres and sparsely-haired ones exhibiting a sponge-like system.

This study suggests that the anchorage of the arrector pili muscle to the extracellular matrix is likely mediated by α5β1 integrin, with α1β1 integrin involved in muscle cell-cell adhesion.

This study observed that the lower part of vibrissa hair roots in adult Wistar rats receives a richer blood supply and structural protection, compared to the upper part.

The researchers reported that mast cell and nerve fiber interactions in mouse skin are highly selective for nerve fiber types and vary depending on the hair cycle phase.

This study found that disulfide bonds in keratin increase its strength and toughness, with some loss of α-helical structure under load, highlighting their role in trichocyte α-keratin's mechanical properties.

In this study, FN-based fiber scaffolds designed using Rotary Jet-Spinning were shown to enhance wound healing and reduce scar formation in a mouse model, suggesting potential for regenerating healthy skin structure.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

In this study, researchers developed a three-dimensional ultrastructural analysis tool using serial block-face scanning electron microscopy to reveal detailed nerve networks and muscle structures in human skin tissues, demonstrating the technique's potential to study structural changes in aging or disease.

This study observed that ECMs produced by papillary fibroblasts showed the largest fibers and supported keratinocyte differentiation better than reticular fibroblast matrices, informing biomimetic material design for skin tissue engineering.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study found that culturing fibroblasts on stiffer substrates mimicking fibrotic wounds led to an aligned EDA fibronectin matrix with thinner fibers and decreased YAP activity, suggesting disrupted signaling that might be restored to promote regenerative wound repair.
