This review discusses the role of perifollicular macrophages in hair growth and suggests targeting them could be relevant for managing hair growth disorders, but reports no new results.

This review discusses the roles of filaggrin and trichohyalin in keratinocyte differentiation and reports no new results; the authors introduce possible hybrid granules in tongue epithelia.

Fibronectin and other basement membrane components increase during hair growth and decrease during rest.

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 Malassezia hyphae in the keratotic plugs of healthy individuals, which contrasts with previous findings of these hyphae primarily in lesions of pityriasis versicolor patients.

This study discovered that adipose tissue infiltration at the isthmus level appears significantly more often in frontal fibrosing alopecia cases compared to controls, suggesting a potential role in the condition's pathology.

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

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 found that careful light microscopy using fluid-mounted hair improves detection of the pili annulati phenotype, which varies widely in expression and affects hair fragility.

In this study, FAPD was characterized in a Chinese population by perifollicular mast cell infiltration, suggesting young individuals may be at higher risk than previously thought.

In this study, researchers used a mouse model to demonstrate that expression of MARCKSL1 in dendritic cells plays a crucial role in modulating fibrotic responses and scar formation during wound healing, suggesting that targeting this expression could offer new therapeutic strategies for scar prevention.

This study reports that a 190,000 molecular weight protein, identified as trichohyalin, may play a matrix role in the development of inner root sheaths in hair follicles.

This study found that fibroblasts from highly regenerative mammals, such as spiny mice and rabbits, exhibit unique metabolic characteristics, including a preference for glycolysis and specific mitochondrial features, which may contribute to their resistance to oxidative stress and support tissue regeneration.

In this study, researchers observed that follicular damage and stem cell loss in frontal fibrosing alopecia may be mediated by immune attacks at the bulge region, suggesting potential for JAK/STAT-targeting treatments to prevent progression.

The conclusion is that CD90 is not a specific marker for fibroblast subtypes and better methods are needed to identify them.

This study observed that mast cells and increased collagen and elastic fibers in the scalp may contribute to male pattern hair loss, but additional research is needed for further understanding.

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.

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 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 study found that fibronectin supports hair follicle regeneration by influencing stem cell behavior through integrin-dependent mechanotransduction, highlighting its potential role in epidermal renewal.

This study found that crosstalk between fibroblasts and endothelial cells significantly contributes to hypertrophic scar formation by enhancing fibroblast activity through cytokine secretion, with pathway analyses suggesting molecular targets for potential therapeutic interventions.

This study found that multiphoton microscopy imaging allows for detailed observation and quantitative analysis of collagen alterations in the progression of endometrial cancer, potentially offering a faster, more accurate method for early diagnosis compared to current protocols.

This study demonstrated that a single multimode fiber can be used for single-shot wide-field reflectance imaging, achieving high correlation with the ground truth and enabling real-time microendoscopy at up to 180 frames per second.

This study found that acellular dermal matrix scaffolds may facilitate full-thickness skin wound healing by promoting a pro-regenerative immune response through M2 macrophage polarization via the Lamtor1 pathway.

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.

This study revealed distinct cellular and transcriptomic differences among various subtypes of cutaneous T-cell lymphoma, particularly highlighting characteristics unique to folliculotropic mycosis fungoides.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

This study introduced a novel microscopy system using an Er3 + −doped femtosecond fiber laser, achieving detailed imaging of biological structures in plant and skin samples with improved spatial resolution for various applications, including in vivo imaging.
