This review discusses the historical development and current challenges in in vitro hair follicle culture, highlighting a need for advanced models using cell lines and tissue engineering, and reports no new results.

This study reports that using nanogel and layer-by-layer self-assembly to encapsulate single dermal papilla cells can form cell spheroids that regenerate hair follicles successfully in a hair follicle regeneration model.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This review discusses the mechanisms by which isotretinoin and hormonal therapy treat acne through their effects on sebaceous glands, reporting no new clinical results.

This study found that IGF-1 likely plays a crucial role in regulating hair growth and alopecia, with balding scalp follicles secreting less IGF-1 than nonbalding counterparts.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

This review examines the molecular mechanisms of the circadian clock and its effects on cardiovascular functions, proposing a novel non-invasive method using hair follicle cells to assess circadian regulation in humans, but reports no new clinical results.

This review discusses the potential role of androgen receptor CAG repeat polymorphism testing in hypogonadism management for both sexes, but its clinical utility remains unclear and requires further investigation.

Eating isoflavone can help mice grow hair by increasing a growth factor.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This review examines cell-based therapies for limbal stem cell deficiency, highlighting epidermal and hair follicle-derived stem cells as promising candidates for future clinical trials, but reports no new clinical findings.

This study identified that rose, thyme geraniol, palmarosa, and tolu balsam essential oils activate TRPV1, with citronellol and geraniol as newly recognized agonists.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

This review discusses changes in keratin structure or gene expression that result in various skin disorders and reports no new clinical findings.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This study identified numerous size polymorphisms in the human ultrahigh sulfur KAP4 genes due to intragenic sequence variations, suggesting these polymorphisms may have arisen through deletions and duplications during evolution.

This study found that 3-Deoxysappanchalcone may stimulate hair growth in mice by promoting proliferation of hair follicle dermal papilla cells through WNT/β-catenin and STAT signaling modulation.

This study presents a validated HPTLC method for simultaneously determining five BPH drugs, showing high sensitivity and selectivity for potential use in quality-control analysis.

This review discusses the potential of ozone therapy as an adjuvant to radio-chemotherapy for cancer patients, noting enhanced treatment effects and improved quality of life, but it presents no new research findings.

This study found that local androgen biosynthesis and metabolism in human sebaceous glands play a crucial role in sebum synthesis and secretion.

This review discusses the therapeutic potential of potassium channel openers for various conditions, but notes that their clinical role is not yet fully established.

This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

Genetic research has advanced our understanding of skin diseases, but complex conditions require an integrative approach for deeper insight.

In this study, mutations in the vitamin D receptor were identified in Brazilian children with rickets and alopecia, leading to impaired receptor activation and reduced 24-hydroxylase expression.

This review discusses the chemical effects of UV radiation on hair, hair photoaging, and photoprotective measures, and calls for more focused research in hair photoprotection as a field.

This study found that only minoxidil encapsulated in cationic vesicles significantly promoted hair growth in mice, likely due to its higher retention on the skin.

This study generated FGF5-knockout Dorper sheep using the CRISPR/Cas9 system, resulting in significantly increased fine-wool and active hair-follicle density, and explored downstream signaling pathways for potential applications in androgen alopecia treatment.

This review discusses the role of stem cell heterogeneity and compartmentalization within the epidermis and highlights their significance as niches for neighboring cells, without reporting new experimental results.

This case report describes successful CO2 ablation treatment of porokeratotic adnexal ostial nevus in an 8-year-old boy, with marked improvement over a 12-year follow-up.
