This review discusses novel treatments for androgenetic alopecia, including therapies like platelet-rich plasma and adipose-derived stem cells, and reports no new clinical results.

This study suggests that with aging, mouse corneal renewal increasingly relies on Lrig1+ stem cells as CD44 expression and Wnt activity decline.

This study found that the PPAR-γ modulator AGED can reverse epithelial-mesenchymal transition in hair follicles affected by lichen planopilaris ex vivo, suggesting potential for treating scarring alopecias.

This study suggests that macrophages play a more substantial role in the pathogenesis of Lichen planopilaris compared to Frontal fibrosing alopecia, as indicated by increased CD68+ cells in Lichen planopilaris.

This study found that dermal white adipose tissue surrounding human hair follicles enhances proliferation, pigmentation, and hair shaft elongation in an ex vivo setting.

This study found that the cell of origin in mouse skin affects melanoma phenotype and response to therapies, despite the presence of the same genetic mutations.

This study found that dihydrotestosterone alters the balance of Wnt pathway regulators in dermal papilla cells, hindering hair follicle stem cell differentiation and contributing to hair follicle miniaturization.

This case report identifies a novel LIPH gene mutation linked to autosomal recessive woolly hair/hypotrichosis in a Japanese boy, expanding the spectrum of known mutations associated with this condition.

This study suggests that enhancing endocannabinoid tone with an EMT-inhibitor may have anti-inflammatory effects and slightly increase sebaceous lipid production, which could be beneficial for dry skin conditions.

This study explored the role of nine specific miRNAs in human hair follicles, revealing significant miRNA/mRNA correlations for miR-24, miR-31, and miR-106a and identifying target genes involved in hair biology.

Small molecule DMF improves psoriasis and multiple sclerosis, adult skin cells can be made to grow new hair, certain skin cells initiate hair growth, IL-17C controls gut health and can cause skin inflammation, and skin cells produce IL-17 that can lead to psoriasis.

Diphencyprone initially increases mouse hair growth, then slows it, possibly due to changes in specific protein levels.

This study found distinct gene expression profiles in the parietal and occipital scalp of individuals with androgenetic alopecia, linked to developmental origins and susceptibility to hair loss, offering insights into genetic and epigenetic factors involved in AGA.

This study found that a decrease in estradiol levels in women is associated with increased hair shedding due to weakened anchoring of telogen hairs.

Phototrichogram helps assess hair loss severity.

PGD2 stops hair growth and is higher in bald men with AGA.

This review discusses various methods for obtaining stem cell-derived conditioned media and its applications in disease treatment, finding generally positive results but highlighting the need for standardized production methods.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

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 newborn mouse skin organoids can robustly grow hair in vivo, while adult organoids require specific interventions to restore their hair-forming ability.

This review examines the evolving understanding of lymphatic vessel development, emphasizing new cellular mechanisms and lineage diversity, while discussing experimental methods and identifying key knowledge gaps.

This review explores the novel roles of white adipose tissue in tissue homeostasis and regeneration, emphasizing its impact on epithelial, muscle, and immune tissues, and reports no new clinical results.

This study found that the PI3K-Akt signaling pathway is essential for regenerating new hair follicles when epidermal stem cells and skin-derived precursors are combined, suggesting potential therapeutic applications for hair regeneration.

This review discusses the paracrine properties of cardiac stem cells and pericytes in regenerative medicine for ischaemic diseases and reports no new clinical results.

This review found that the current evidence on using platelet rich plasma to treat non-cicatricial alopecia, such as androgenetic alopecia and alopecia areata, is of low quality and yields controversial results.

This review analyzes therapies used for androgenic alopecia, highlighting potential advances from stem cell technologies and regenerative medicine, and reports no new clinical results.

This review discusses platelet-rich plasma for androgenic alopecia and reports beneficial effects on hair density and quality, but suggests more rigorous studies are needed for conclusive evidence.

This review explores factors affecting graft growth and survival in hair restoration, emphasizing the importance of fundamental care practices while considering advanced storage solutions and additives, but reports no new findings.

This study demonstrated that troxerutin may protect human dermal papilla cells from H2O2-induced damage and suggests potential in treating alopecia by inhibiting ROS-mediated cellular damage.
