This article reviews the regulation of gene expression and assembly of intermediate filaments but presents no new findings.

This study discovered a conserved "fiber-like-motif" of melanosomes aligned in hair across various mammalian species, shedding light on the internal structure that influences hair's thermal and mechanical properties.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This study found that basement membrane components and structures in mouse hair follicles are highly specialized for specific inter-tissue interactions, with laminin α5 playing a crucial role in hair cycle regulation and anchoring.

This study found that fibronectin is crucial for hair follicle stem cell function and regeneration, with its deletion impairing regeneration but restoration by dermal injection of exogenous fibronectin.

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This study suggests that human trichohyalin may function as a flexible rod linking keratin intermediate filaments and as a scaffold protein in hair follicle and epidermis cell envelopes.

This research observed that 3D electrospun micro/nanofibrous sponges, without using chemical crosslinking agents, supported enhanced cell growth, vascularization, and skin regeneration in diabetic rats compared to 2D fiber membranes, making them promising for 3D tissue regeneration.

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.

Keratin structure changes during keratinization, but the exact model remains uncertain.

This study demonstrates a sample preparation method for wool follicles that allows for clear keratin labeling and ultrastructural preservation in microscopy, reducing common artefacts from conventional fixation techniques.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

In this study, the researchers found that optic atrophy 1 (OPA1) is involved in the transition between filamentous and rounded mitochondria in hair follicle dermal papilla cells, potentially influencing cellular energy dynamics.

This study observed that the mechanical connection between hair follicles and connective tissue in human fetal scalp skin is weaker than in the corresponding skin components, reflecting dynamic processes in hair growth.

This study found that pen-type microwells enhanced hair follicle germ formation by promoting cell assembly, suggesting microwell array geometry significantly influences in vitro hair follicle development.

This study observed that a novel extracellular matrix hydrogel made from human fibroblast-derived matrix improved wound healing in animal models, showing significant effects such as hair follicle formation, reduced inflammation, enhanced pro-healing growth factor levels, and interaction with macrophages, compared to traditional collagen hydrogels.

This study suggests that a novel micropatterned dermal–epidermal matrix (μDERM) enhances keratinocyte function and epidermal morphology, offering potential improvements in skin substitute design for wound healing applications.

This review summarizes techniques like Raman spectroscopy, nanoindentation, and small-angle X-ray scattering to explore the biophysical interactions in collagen fibers, aiming to enhance understanding of fibroblast behavior and mechanisms involved in organ fibrosis and healing processes.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.

This study found that in anagen hair follicles, the basement membrane zone components showed decreased expression in the lower hair bulb, with a complete absence of BP230 at the dermal papilla junction, suggesting an incomplete hemidesmosome structure in these regions.

This research explores the use of serial block-face scanning electron microscopy to model the complex architecture of sheep wool fibres, focusing on the role and distribution of para- and ortho-cortical cells in determining wool curliness, though the mechanism remains unclear.

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.

In this study, researchers observed that spiral ganglion neurites created more branched networks near FGF-1-coupled beads compared to control beads, highlighting FGF-1's role in hair cell innervation development.

This microscopy study examined the non-keratinous regions of human hair fibers, revealing detailed morphology that could help understand how external influences affect hair structure.
