This study found that angiogenin is expressed in human dermal papilla cells, where it might stimulate hair growth by promoting cell proliferation and local skin angiogenesis.

This study found that injury affects the behavior of hair follicle dermal stem cells, steering them towards recruitment into the dermal papilla, a shift influenced by the hair cycle stage.

In this study, researchers used a rodent model to uncover key changes in how hair fibers detach, suggesting that the exogen phase should be subdivided based on club fiber status.

This review discusses "follicular hypoglycania" as a potential pathology in hair growth disorders and reports that proteoglycan replacement therapy may improve hair loss treatments, though it presents no new clinical trial results.

This study found that Sox10 may play a role in early hair follicle development and cycling, as it is expressed in specific regions of the hair follicle during different phases of the hair cycle in mice.

In this study, rice bran mineral extract increased expression of anagen-related proteins and decreased inflammatory markers in human dermal papilla cells, suggesting potential for hair growth enhancement and prevention of hair loss.

This study found that Chamaecyparis obtusa oil increased hair follicle cell proliferation and maintained the anagen phase in mice, suggesting a potential for promoting hair growth.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

This review discusses recent advances in hair follicle research, highlighting therapeutic and cosmetic applications, but reports no new study results.

This study suggests that the expression of the DP2 receptor is higher in balding scalp cells and that its knockdown could inhibit the transition to the catagen phase in cultured human hair follicles, potentially counteracting hair growth inhibition associated with male pattern baldness.

In this study, researchers found that recombinant human HAPLN1 promoted hair growth in mice and human hair matrix cells by activating specific signaling pathways, suggesting it may offer a potential hair loss treatment with fewer side effects than existing medications.

This study investigated the hair growth-promoting effect of topical nebivolol cream in mice, but the abstract does not provide specific results or conclusions.

This study found that in adult mouse skin, reduced levels of histone H3 K4/K9/K27me3 during hair follicle stem cell quiescence are linked to proper tissue homeostasis.

This review discusses the roles of the hairless (HR) protein as a corepressor, particularly its impact on RORα-mediated transcriptional repression, and reports no new experimental findings.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

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 demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.

This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

In this study, miR-31 was found to play a significant role in hair cycle regulation in mice by controlling key gene expressions involved in hair growth and differentiation.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.

In this study, researchers used transcriptome sequencing and bioinformatics analysis to identify important genes and pathways involved in the transition between hair growth phases, offering new insights into hair follicle cycle regulation and development.

This study found that keratinocytes derived from the germinative epithelium of ovine hair follicles have extensive in vitro growth potential, challenging the idea that these cells are solely transit-amplifying.

This study found that the phenotype of Hedgehog/Gli-driven skin tumors in mice depends on the cell of origin, tissue context, and level of oncogenic signaling.

This study found that alopecia in VDR-null mice persists despite undetectable vitamin D levels, indicating a defect in epithelial-mesenchymal communication due to the absence of ligand-independent receptor function.

This study found that heterozygous mice overexpressing Claudin-6 experienced alterations in epidermal and hair follicle differentiation, leading to distinctive coat characteristics and a disrupted epidermal permeability barrier.

In this study, researchers found that SIRT7 activates quiescent hair follicle stem cells to promote hair growth in mice by triggering the telogen-to-anagen cycle transition, with potential implications for age-related hair loss.
