This review examines the effects of various factors on the molecular and nanostructural ordering of human hair, highlighting its potential as a diagnostic material for environmental and public health monitoring, but reports no new experimental results.

The document recommends both books for medical training in aesthetic surgery and wound healing.

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.

In this study, women with diffuse hair loss reported that Proteoglycan Replacement Therapy with Nourkrin® improved hair growth and appearance, boosting their confidence and satisfaction with the treatment.

This integrative literature review revealed that chronic stress, characterized by elevated cortisol levels, negatively impacts hair follicle integrity and contributes to alopecia by promoting the premature transition from the growth phase to the resting phase of the hair cycle.

This study suggests that Ptprq in the hair bundles may exist as multiple isoforms that are differentially expressed throughout development and affect the organization of stereocilia in the chick inner ear.

This study found that macrophages treated with keratin in vitro were more similar to anti-inflammatory M2 macrophages and reduced astrocyte reactivity, potentially limiting secondary inflammatory damage after spinal cord injury.

This review discusses the role of heparan sulfate proteoglycans in regulating stem cell fate and highlights their potential as targets for addressing hair loss, without reporting new clinical results.

This study reveals that CSPG4-positive basal cell keratinocytes show distinct global gene expression from CSPG4-negative cells, despite similar colony-forming efficiency.

This study found that certain plasma protein ratios, specifically AGRN/HSPG2 and DECR1/FKBP1B, were significantly associated with an increased risk of alopecia areata, indicating potential causal relationships but reverse causality was not supported.

This study highlights that human hair follicle dermal papilla cells and glypicans play crucial roles in regulating hair follicle stem cell differentiation.

This study demonstrated that the large molecule versican plays a critical role in hair induction in dermal papilla cells, with potential implications for developing new hair growth treatments.

This study found that Tsukushi facilitates wound healing in mice by regulating macrophage function and myofibroblast differentiation.

This study suggests that collagen XVIII and its variant endostatin may play a role in regulating Wnt-signaling in hair follicles, affecting wound healing and skeletal development in mice.

Collagen XVIII and Bmx tyrosine kinase are important for hair growth and skin cancer development.

This study found that dermal papilla and dermal sheath cells from human scalp tissue differ from interstitial dermal fibroblasts in morphology and produce varying levels of TGF-beta 2.

This study reports that versican expression plays a crucial role in maintaining the anagen phase and hair inductive properties, as shown in a transgenic mouse model and hair growth assays.

This study identified the dermal sheath as a driver of hair follicle regression through muscle contraction, essential for reuniting niches and stem cells to regenerate tissue structure during homeostasis.

This study examines the structure of the "sinuskissen" in cat hair follicles, revealing it as a loose connective tissue susceptible to changes in aqueous flow, and describes its variable three-dimensional shapes.

In a study using a placebo-controlled design, the researchers found that coenzyme Q10 may enhance gene expression of age-relevant hair keratins in human hair roots, suggesting potential anti-aging benefits for mature hair.

This review discusses the differences in wound healing between fetal and adult skin, highlighting the potential to uncover genes for scarless repair that could improve adult wound healing.

This review discusses the unique capacity of fetal skin to heal wounds without scarring and notes that while many factors have been identified, the complete mechanism of fetal wound healing remains unclear.

This review discusses the roles and mechanisms of glycosaminoglycans in wound healing and presents challenges and potential applications for GAG-based biomaterials without reporting new experimental results.

This study found that incorporating cell-adhesive ligands into 3D peptide hydrogels supports the survival and osteogenic differentiation of human amniotic mesenchymal stem cells.

This study suggests that fibromodulin may regulate transforming growth factor-β activity during scar formation, influencing the transition from fetal scarless repair to adult scar-forming repair in rats.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This study found that β-catenin signaling increases in newly born glial cells in the cortex after traumatic brain injury in mice, suggesting potential targets for enhancing recovery through the Wnt/β-catenin pathway.

This review discusses the complex relationship between stress and various skin conditions, highlighting the role of the skin in the stress response and the brain-skin communication pathways, but reports no new research findings.

This study observed that hepatocyte adhesion to human hair keratin biomaterials was mediated by the hepatic ASGPR, as blocking this receptor reduced cell attachment.

Human enzymes can detoxify harmful substances but might also increase their cancer risk.
