This study found that hair loss in an Olmsted syndrome mouse model with a Trpv3 mutation was linked to premature keratinocyte maturation, affecting hair follicle structure and function.

In this study, researchers found that Sox9 is critical for determining whether Nestin⁺ stem cells in adult mouse skin develop into melanocytes or glial cells, offering insights into possible paths for melanoma research.

This study demonstrates the potential of infrared spectral imaging to assess hair follicle structures and heparan sulfate proteoglycan distribution across different phases of the hair growth cycle, offering promise for alopecia research.

Using a transgenic pig model, this study demonstrated that LGR5 is a marker of hair follicle stem cells across different species, with important similarities and differences in gene expression and developmental processes.

This review discusses how neuroendocrine regulation affects human hair follicles and suggests potential therapeutic targets, but it reports no new clinical results.

In this study, researchers found that thrombin may influence cyclic hair growth through its receptor PAR-1, although it does not seem to stimulate dermal papilla cell proliferation physiologically.

This study found that human mesenchymal stem cell-derived extracellular vesicles promote the proliferation and migration of hair follicle cells and increase hair shaft elongation in cultured human hair follicles.

This study suggests that Sox13, although dispensable for epidermal development, serves as a marker for early hair follicle development in Sox13-LacZ knock-in mice.

This article reviews in-vitro and cell-free methods for assessing the efficacy of herbal ingredients in cosmetic formulations for skin health and hair growth, but it reports no new clinical results.

In this study, researchers found that dentin sialoprotein and phosphophoryn are present in rat and mouse hair follicles, suggesting these proteins may play a role in hair follicle development, similar to their role in dentin mineralization.

This study observed that fetal hair follicle melanocytes varied in morphology and development stages, with melanosomes undergoing degradation into irregular pigment particles within keratinocytes.

This study suggests that the MLKL-targeting inhibitor Necrosulfonamide promotes hair growth and counteracts DHT inhibition by activating Wnt signaling in hair follicle cells, revealing potential avenues for anti-alopecia drug development.

In this study, kartogenin promoted hair growth by enhancing cell proliferation and migration in vitro and extended hair length in mice, suggesting its potential as a treatment for hair loss.

In this study, FGF12 was found to promote hair growth in mice by inducing the anagen phase of hair follicles, suggesting potential for hair loss therapy.

In this review, researchers reported that pyroptosis, a type of inflammatory cell death linked to inflammasome activity, is a key factor in the pathogenesis of alopecia areata and may present new therapeutic opportunities, though most treatments are still in early research stages.

In this study, researchers linked SARS-CoV-2 infection to telogen effluvium in some COVID-19 patients by observing the accumulation of viral proteins in hair follicle cells, which may trigger stress responses and cell death, suggesting hair follicles as a potential target in COVID-19.

This study in Gansu alpine fine-wool sheep identified two SNPs in the KRT71 gene that significantly affect wool length, with distinct expression patterns observed in hair follicles, suggesting KRT71 as a candidate gene for enhancing wool production traits.

This study established a Krt24-CreERT2 mouse line targeting outer bulge hair follicle stem cells, finding these cells crucial for hair follicle development and repair, particularly following ionizing radiation exposure.

This study examined the cytodifferentiation stage of hair follicle development in cashmere goats, identifying nine cell populations and key regulatory pathways, including transcription factors and keratin genes, that may influence fiber quality and inform breeding strategies.

This study identified key proteins, FKBP10 and FBN2, that promote the growth cycle of secondary hair follicles in cashmere goats, with higher expression in the anagen phase, offering insights into mechanisms potentially enhancing cashmere yield and quality.

This study found that 1,25-dihydroxyvitamin D3 promotes hair growth and regeneration in mice by prolonging the anagen phase and counteracting DHT's inhibitory effects, suggesting its potential therapeutic role for androgenetic alopecia.

This study examined the formation of acquired curved hair and found that the fusion of hair matrix cells during follicle regeneration contributes to asymmetric follicle shapes and curved hair, potentially linked to changes in type IV collagen and protein expression levels.

In this study, researchers found that knockdown of ABCA5 in primary human hair follicle keratinocytes disrupted cholesterol homeostasis and transportation, suggesting its potential role in hair growth disorders by affecting intracellular cholesterol compartmentalization and LXR-mediated transcriptional activity.

This study used infrared spectral imaging to show for the first time the distribution of glypican-4 and glypican-6 in hair follicles across different growth phases, highlighting the potential of this technique for studying alopecia.

This review discusses the complexity of identifying hair follicle antigens involved in alopecia areata and reports no new clinical results, emphasizing the need for further research on autoantigen identity.

This study demonstrated that injecting reconstructed dermal papilla-like tissues in mice led to new hair growth, suggesting potential future applications in hair transplantation and baldness treatment.
