This study developed a minimally invasive cryo-microneedles array patch (cryo-MAP) technique for transplanting hair follicle organoids, showing successful hair growth and complex skin structure regeneration with over 86% success in 15 days, opening new possibilities in tissue engineering.

In this study, orally administered Centella asiatica extract, standardized for asiaticoside content, significantly improved skin barrier function, elasticity, and reduced signs of UVB-induced photoaging in hairless mice, highlighting its potential as a nutricosmetic for skin health.

Versican in dermal papilla cells is crucial for healthy hair growth.

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 found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.

This study found that stem cell factor combined with fibronectin and type IV collagen promotes migration of amelanotic melanocytes, which may help explain their movement during vitiligo repigmentation.

In this case report, a 27-year-old woman with a swelling on her neck was initially misdiagnosed with squamous cell carcinoma, but was later identified as having pilomatrix carcinoma with lymph node metastasis, highlighting the importance of accurate diagnosis for effective treatment and prognosis improvement.

This study observed that basal cell carcinomas with matrical differentiation may derive from hair follicles, with .-catenin potentially playing a key role in tumor development and differentiation.

This case study found that a skin lesion in a Samoyed dog did not match any single known follicular cyst or neoplasm type described in the literature.

In this study, extracts of Zataria multiflora Boiss. and Matricaria chamomilla, combined with minoxidil, significantly improved hair growth in androgenetic alopecia patients by potentially inhibiting 5α-reductase activity.

This study found that the volume of a hair follicle's dermal papilla is strongly correlated with its size, primarily due to the number of cells it contains and the volume of extracellular matrix.

This study found that trichocytic cytokeratins, typically found in hair, are also present in nails, filiform papillae of the tongue, and the epithelial reticulum of the thymus.

This study found that in Arabidopsis thaliana, the interaction between extracellular leucine-rich repeat extensins and the receptor-like kinase FERONIA helps control vacuolar expansion, crucial for cellular elongation.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

In this study, researchers identified the ventral matrix as the primary source of nail plate formation, while the dorsal portion is generated by the apical matrix.

This study found that low oxygen conditions and ECM degradation products increased the proliferation and migration of perivascular stem cells without altering their phenotype, suggesting potential roles in tissue repair.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

Epithelial cell growth in rat hair follicles needs contact with mesenchymal cells through the extracellular matrix.

This study found that PHBV cocultured with epithelial and dermal cells might enhance early-stage wound healing by promoting wound closure and re-epithelization more effectively than PHBV/collagen.

This study found that combining adult germinative epidermal cells with non-inductive dermal cells can stimulate hair follicle neogenesis, effectively altering the cells' status to enhance induction.

This study identified a homozygous missense mutation in the KRTHB5 gene linked to pure hair–nail ectodermal dysplasias in a large consanguineous Pakistani family, providing new insights into the condition's molecular pathogenesis.

This study found that keratin 6hf, a type II keratin, is expressed in specific regions of mouse and human hair and suggests potential interactions with keratin 17, impacting hair development and associated disorders.

This study found that ECMs from papillary and dermal papilla fibroblasts support normal basement membrane formation, suggesting potential improvements for therapeutic biomaterials in skin engineering.

This study found that a novel skin patch combining extracellular matrix and ciprofloxacin promotes advanced wound healing and skin regeneration in mouse models of infected wounds.

This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

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 dermal papilla cells in culture may enhance and attract follicular epithelial cell growth, suggesting their pivotal role in hair and follicle development.

Minoxidil improves blood flow and vessel flexibility, potentially helping with vascular stiffness.
