This study found that the loss of Smad4 in keratinocytes reduces Dsg4 expression via disrupted BMP signaling, contributing to hair follicle degeneration and alopecia.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

The conclusion is that androgenetic alopecia and senescent alopecia have unique gene changes, suggesting different causes and potential treatments for these hair loss types.

This study found that combining ablative fractional CO₂ laser therapy with hair growth factors significantly increased hair density in men with androgenetic alopecia compared to using growth factors alone.

This study found that l-carnitine stimulated hair growth in vitro by promoting proliferation and reducing apoptosis in human scalp hair follicles, suggesting potential as a treatment for hair loss.

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 discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This study developed a new protocol to efficiently produce skin dermal stem cells from human induced pluripotent stem cells, which may aid in treating various skin disorders.

This study suggests that minoxidil is a potent stimulator of elastin expression in embryonic skin fibroblasts, primarily affecting elastin mRNA levels, without impacting cell proliferation during the stationary phase.

This study found significant changes in gene and protein expression related to hair follicle development in Rex rabbits' skin during the first 8 weeks of life.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study identified several genes regulated by dihydrotestosterone in an SV40T-transformed human dermal papilla cell line, which may play a role in androgen-mediated hair growth regulation.

In this study, Nec-1s was found to promote hair growth and may target necroptosis and the Wnt/β-catenin pathway for potential treatment of hair loss.

In this study, transcriptome analysis identified 68 differentially expressed miRNAs in human dermal papilla cells treated with hydrogen peroxide, suggesting they play a significant role in growth arrest and apoptosis.

This study found that MBN, an herbal extract fermented by Lactobacillus plantarum, promoted hair growth and increased related gene expression in C57BL/6 mice.

PRP helps hair growth in common hair loss disorder.

This study found that brain-derived nerve factor protein expression was significantly increased in balding scalp samples from men with androgenetic alopecia, suggesting it may play a role in hair follicle regulation.

This study suggests that CTHRC1, a protein expressed in cardiac fibroblasts, may improve wound repair and prevent cardiac rupture after myocardial infarction by activating a specific signaling pathway.

In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.

This study suggests that human evolution involved accelerated changes in the HR gene, affecting its role in mediating postnatal hair cycling.

In this study, the methanol-ultrasound extract of Dendropanax morbifera leaf showed potential for use in functional cosmetics and hair growth products due to its high antioxidant capacity and effects on growth factor expression without cytotoxicity.

No genetic link between prostaglandins and hair loss found.

This study found that RCS-01 cell therapy for aged skin was well tolerated and associated with increased gene expression related to extracellular matrix homeostasis, suggesting potential skin improvement.

In this study, extracts from three Polynesian plants—Bidens pilosa, Calophyllum inophyllum, and Fagraea berteroana—were found to increase dermal papilla cell proliferation and modulate hair growth-related gene expression, suggesting potential for stimulating hair growth.

This letter reports no new findings and discusses potential concerns regarding 5-alpha reductase inhibitors on lung function, suggesting a reason for discontinuation during the COVID-19 pandemic.

This study observed that using 3D dermal papilla microtissues enhances hair follicle regeneration and gene expression compared to 2D cultures, indicating their potential for hair growth drug screening.

This study found that the 1 mg dose of finasteride was associated with a wide range of adverse effects, including sexual, psychological, and metabolic symptoms, in the FAERS data.

This review examines the diversity and role of stem cells in the adult dermis, noting a lack of precise understanding about their hierarchy and relationship to dermal fibroblast subpopulations, and reports no new results.

This research reported that STAT5 activation in the dermal papilla plays a crucial role in triggering anagen entry during post-developmental hair follicle cycling.

This study identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.
