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.

In this study, the authors identified a role for hair follicles in regulating the formation and sympathetic innervation of arrector pili muscles, influencing hair follicle stem cell activity and potentially explaining hair loss associated with beta-blockers and androgenic alopecia.

In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.

This review synthesizes recent research on exosomes, highlighting their role as key modulators in regenerative outcomes and suggesting they may offer advantages over stem cell-based therapies in process and regulation.

This study found that Cannabidivarin (CBDV) promotes neuronal differentiation and inhibits oligodendrocyte maturation via TRPV1 modulation, highlighting its potential in neural stem cell research.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

This study identified a specific subset of macrophages as a key source of oncostatin M, maintaining hair follicle stem cell quiescence during the resting phase in mice, suggesting a potential target for treating hair disorders.

This study found that hair follicles in both mice and humans may serve as an important site for melatonin synthesis and signaling, potentially influencing hair cycle regulation by modulating keratinocyte apoptosis.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.

The researchers reported that disrupting ATRA signaling by deleting RDHE genes in the hair follicle led to altered hair follicle cycles, composition, and gene expression, indicating RDHEs' role in hair follicle signaling coordination.

This study found that human scalp hair follicles can internally operate a Cori cycle, synthesize glycogen in the presence of lactate, and modulate growth through glycogen phosphorylase activity.

This study found that the selective PPARγ modulator GMG-43AC may inhibit unwanted hair growth by inducing catagen phase while preserving hair follicle epithelial progenitor cells, suggesting potential in anti-hirsutism therapy.

This study found that vitamin A significantly enhanced the proliferation and inhibited apoptosis of rabbit dermal papilla cells under heat stress, likely by modulating miR-195/IGF1 and Wnt10b/β-catenin signaling pathways.

This review discusses the role of various genetic regulators in maintaining human mesenchymal stem cell stemness and highlights strategies for ex-vivo expansion, but reports no new clinical findings.
