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 PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

This study found that overexpression of miR-214 in keratinocytes inhibits hair follicle development and cycling by targeting β-catenin in the Wnt signaling pathway.

This article discusses the role of stratum corneum disruption in dandruff and suggests that treatments improving scalp barrier integrity along with antifungal activity may be beneficial; it reports no new research findings.

This review discusses WHO group 2 anovulation, highlighting polycystic ovary syndrome as a common cause of infertility and noting current treatment options without presenting new clinical results.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

In this study, increased corticosterone from chronic stress prolonged hair follicle stem cell quiescence in mice, inhibiting regeneration, but restoring Gas6 expression overcame this inhibition.

This study found that LGR5 is uniquely expressed in human corneal endothelial cells and maintains endothelial cell phenotypes while inhibiting mesenchymal transformation through the Wnt pathway.

This review discusses recent advances in the therapeutic potential of exosomes for wound healing, highlighting their benefits and challenges but reports no new clinical results.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This study found that quiescence in hair follicle stem cells acts as a tumor suppression mechanism for cutaneous squamous cell carcinoma, with Pten activity necessary to maintain this state.

This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.

This review discusses current therapeutic targets and treatments for androgenic alopecia but reports no clinical results; the authors highlight the challenge of developing multi-target drugs for effective treatment.

This study found that overexpression of the transcription factor Tcf3 accelerates keratinocyte migration and skin wound healing in mice, highlighting its potential as a therapeutic target for wound repair.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

The document explains different types of hair loss, their causes, and treatments, and suggests future research areas.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that the antiandrogen drug enzalutamide reduced TMPRSS2 levels and significantly decreased SARS-CoV-2 entry and infection in lung cells, supporting further clinical trials for COVID-19 treatment.

This study found that miRNA expression profiles in follicular fluid are altered in women with PCOS, with certain miRNAs potentially useful for distinguishing patient subtypes and contributing to understanding PCOS heterogeneity.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

Keratin peptides can change hair shape gently without harsh chemicals.

This review found that low-level laser therapy appears promising in improving hair regrowth and patient satisfaction in androgenetic alopecia, though results should be interpreted cautiously.

This study suggests that women with polycystic ovary syndrome may have a distinct metabolomic profile, differing in levels of amino acids, organic acids, and lipids compared to controls.

This study suggests that TGF-β 2 plays a critical role in hair follicle morphogenesis and may enhance the effectiveness of future cell therapies for hair regrowth using expanded dermal papilla cells.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

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.
