This study observed that osteopontin mRNA levels in rat hair follicles vary throughout the hair cycle, peaking during the catagen phase and disappearing in the telogen and anagen phases.

This review explores the potential of neuro-driven hydrogels for skin and nerve regeneration, integrating biochemical cues and advanced technologies like AI for personalized wound healing, but notes the need for further validation and trials before clinical use.

Vitamin D3 affects cell differentiation in specific skin areas.

In this study, researchers found that psoriasis patients with untreated lesions showed increased activation of defensins, matrix metalloproteinases, and neuropeptides, which may be stimulated by specific inflammation pathways.

This study found that the dysfunction of hair follicle dermal stem cells with age contributes to hair follicle aging and hair loss in mice.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

This study found that activin A significantly enhances wound healing by stimulating granulation tissue formation and re-epithelialization in mice, and suggests potential in developing treatments for stroke and brain trauma.

This review explores the diverse roles and heterogeneity of fibroblasts across different organs, highlighting their potential involvement in both normal tissue functioning and fibrotic diseases, but reports no new experimental results.

This study re-examined the structure of lanceolate endings in rat vibrissae, suggesting that their apical cones may function as a transducer site for detecting hair movements.

This study reports that flaky skin mice exhibit skin and nail features that closely resemble human psoriasis vulgaris, suggesting they may serve as a natural model for this condition.

This study found that in alopecia areata, hair bulbs are blocked in an early growth stage due to impaired metabolic function in the surrounding connective tissue, hindering hair growth.

In this study using C57BL/6N mice, the researchers found that skin thickness, mast cell counts, and immunoreactive density of certain cytokines increased at various stages of hair follicle growth following depilation.

This study found that hyperbaric oxygen treatment in rats led to structural changes in epidermis and dermis, including decreased E-cadherin expression and increased connective tissue.

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 distinct changes in the ultrastructure of Hexi cashmere goat hair follicles throughout the year, highlighting stages with specific cellular and structural characteristics.

In this study, the authors reported that in rat skin affected by localized calciphylaxis, although regeneration occurs and some connective tissue remains, the regenerate resembles scar tissue with reduced hair presence and lacks restored elastic fibers.

In this study, histologic analysis of rat skin with localized calciphylaxis indicated that although the skin showed potential for regeneration, the result was incomplete and resembled scar tissue with diminished hair presence.

This study developed a tannin-modified cellulose-polypyrrole dressing that accelerates wound healing by enhancing granulation tissue, optimizing collagen, and stimulating angiogenesis, while providing antibacterial protection against S. aureus and E. coli.

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

In this study, Flii overexpression in mice enhanced fingertip regeneration and nail formation after both distal and proximal amputations, suggesting a role in digit and hair follicle regeneration possibly involving Wnt signaling.

This study reports that multiple pyogenic granuloma-like lesions can occur at punch graft sites following hair transplantation, highlighting a potential complication for physicians to be aware of.

In this study, researchers found that miR-3606-3p is significantly downregulated in skin fibrosis and correlates with disease severity, with its ability to inhibit key signaling pathways suggesting potential therapeutic applications for conditions like systemic sclerosis and keloids.

This study found that young men using finasteride for androgenic alopecia experienced erectile dysfunction and signs of erectile tissue fibrosis, alongside symptoms like low libido and mood changes.

This review discusses current hypotheses about cicatricial alopecia's pathogenesis, including lymphocyte-mediated mechanisms and sebaceous gland defects, and reports no new results, emphasizing the need for systematic research.

This review discusses epithelial-mesenchymal interactions in hair follicle development and their regulation by molecular signals, but reports no new results; the authors emphasize the need for further research to apply these findings clinically.

This review discusses the connection between hair follicles and dermal adipose tissue, suggesting that improving the adipogenic environment could be important for treating alopecia and enhancing hair restoration procedures, but reports no new results.

This study observed that red sindhi cattle have variations in skin structure between age and sex groups, with more developed skin appendages in adults and a higher density of sweat glands in younger cattle.

This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

This study found that the KrasG12D mutation alters ERK signal dynamics in hair follicle stem cells, leading to tissue deformation, and suggests a collective effect of mutant cells is necessary for disruption.
