This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This study found that the retinoid all-trans retinoic acid induced a catagen-like stage in human scalp hair follicles, suggesting upregulation of TGF-beta2 as a contributing mechanism.

This article reviews recent advancements in understanding and treating androgenetic alopecia, focusing on new genetic insights, stem cell roles, and diagnostic tools, without reporting new clinical results.

This review discusses recent discoveries about the role of Eda and other TNF-related cytokines in skin appendage development and reports no new experimental results, highlighting developments since the last comprehensive summary in 2003.

Sericin hydrogels heal skin wounds well, regrowing hair and glands with less scarring.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This study found that Sophora flavescens extract may promote hair growth in mice by inducing earlier hair cycle changes and regulating growth factors in dermal papilla cells.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

This review discusses the role of tumor suppressors in controlling tumor-associated inflammation and suggests that targeting this inflammation may counteract the effects of tumor suppressor loss.

This study found that disrupting Smad4 signaling in young mice led to overactivation of follicle stem cells, causing hyperplasia and depletion of the stem cell niche.

This article discusses the need for rational strategies in developing hair loss drugs targeting specific events in hair follicle cycling, reporting no clinical findings but emphasizing the importance of understanding molecular controls.

In this study, transgenic mice expressing a truncated form of latent transforming growth factor-β-binding protein exhibited altered hair cycles due to increased active transforming growth factor-β, impacting keratinocyte proliferation and hair cycle phases.

This study found that basement membrane components and structures in mouse hair follicles are highly specialized for specific inter-tissue interactions, with laminin α5 playing a crucial role in hair cycle regulation and anchoring.

This study found that Puerariae Flos extract inhibited testosterone 5α-reductase and promoted hair growth in mouse models, suggesting its potential use for treating androgenic alopecia.

This study found that red ginseng oil and its major components improved hair regrowth in testosterone-treated mice by promoting an earlier anagen phase and altering related gene expressions.

This study found that applying a topical inhibitor of TGF-β1 may enhance scar maturation and improve the appearance of hypertrophic scars in a nude mouse model after two weeks.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.

In this study, rice bran supercritical CO2 extract demonstrated potential to promote hair growth in mice, increasing hair follicles and growth factor expression, similarly to 3% minoxidil.

This review discusses the developmental regulation of wound healing mechanisms in mammals, focusing on the role of the Wnt and TGF‐β signaling pathways, and reports no new clinical findings.

This review discusses the role of the CXXC5 protein as a transcription factor and signaling coordinator, noting its involvement in embryonic development, tissue homeostasis, and diseases such as tumorigenesis, but reports no new experimental findings.

This study suggests that type IV collagenases, MMP-2 and MMP-9, play important roles in the hair cycle by regulating the expression of VEGF, IGF-1, and TGF-β in mice.

This study found that the type IV collagenases, MMP-2 and MMP-9, play significant roles in the hair cycle, potentially through their influence on VEGF, IGF-1, and TGF-β expression.

This study reviewed the current state of intralesional therapy for keratoacanthoma, finding that while methotrexate, 5-fluorouracil, and interferon alpha are common agents, guidelines are still needed, and histopathological confirmation is advised to prevent misdiagnosis with squamous cell carcinoma.

This study found that the progesterone metabolite 3α-THP increased the proliferation and gene expression of human glioblastoma cells, suggesting a role in tumor progression.

This review compiles existing data on frontal fibrosing alopecia and highlights the promise of 5-alpha reductase inhibitors as a treatment option, while noting the need for clarity on its cause and progression.

This review highlights that frontal fibrosing alopecia’s increasing incidence may involve immune, genetic, hormonal, and environmental factors, yet its pathogenesis remains complex and not fully understood.

This study found that the activation of ER‑β increased keratinocyte proliferation and gene expression related to epidermal regeneration, enhancing wound healing in both cell models and rats.

This study found that ginsenoside F2 may suppress hair cell apoptosis and improve hair growth outcomes in a DHT-induced hair loss model more effectively than finasteride.
