This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

This study found that injecting growth factor concentrates into the scalp of five patients with androgenic alopecia led to notable improvements in hair density and quality over eight weeks, with patients reporting satisfaction and minimal side effects.

In this study, deleting the Igf1 receptor in specific skin cells of mice affected hair follicle cycling but not overall skin health, suggesting Igf1r's role in hair cycle regulation through Bmp-4 activation.

Non-classical 21 hydroxylase deficiency is an underdiagnosed cause of female hair loss and polycystic ovarian syndrome.

In this study, researchers found that WNT activation influenced FGF expression in human scalp-derived fibroblasts, with mouse model results showing FGF9 increased hair follicle number and diameter, while FGF7 reduced diameter.

This study investigated the effects of GFC with FGF5s and NMN at a depth of 0.8 mm using a microneedle for treating hair loss, but the abstract provides no measurable results.

This study found that growth factor concentrate provides quicker improvements for patterned hair loss, but platelet-rich plasma offers more sustained benefits after treatment.

This study introduced a new in vivo angiogenesis assay using Gelfoam implanted in ND-GFP transgenic mice to efficiently identify angiogenesis stimulators and inhibitors through GFP visualization.

This study found that KF19418 stimulated hair follicle growth in vitro and accelerated hair regrowth in a mouse alopecia model, with effects comparable to minoxidil.

This study found that recombinant human FGF9 expressed in Arabidopsis thaliana oil bodies significantly promoted the proliferation of NIH/3T3 cells.

Mutations in the Sgk3 gene cause fuzzy hair in mice.

In this study, researchers found that FGF9 plays a significant role in sheep wool growth by accelerating the proliferation and cell cycle of dermal papilla cells, potentially through regulation of the Wnt/β-catenin signaling pathway.

This study found that ectopic expression of FGF5s in transgenic Chinese Merino sheep increased wool length and greasy fleece weight compared to non-transgenic controls.

This study developed a potent Wnt surrogate with high specificity for the Fzd7 receptor in mice, promoting full hair follicle regeneration and robust hair growth, suggesting potential applications in tissue development and targeted regeneration.

This source provides supplementary materials for the Carnivore Follicular Integrity Framework, a theoretical model proposing that animal-based diets may support hair follicle stability through several biological mechanisms. The materials include definitions, nutrient tables, and mechanistic notes but do not report empirical results.

This study suggests that fibroblast growth factors FGF-4, FGF-8, and FGF-9 may play redundant roles as signals in epithelial-mesenchymal interactions during multiple stages of tooth development in mice.

This study reported that plant-produced basic fibroblast growth factor effectively promoted cell proliferation and collagen production in vitro, suggesting potential applications in cosmetics for antiaging and hair growth.

This paper presents consensus guidelines for standardized diagnostic criteria and assessment methods for frontal fibrosing alopecia to improve clinical research and data collection globally.

This study found that women with female pattern hair loss exhibited hormonal imbalances, with the Free Androgen Index being a particularly effective diagnostic marker.

This study found that intermittent treatment with FTI lonafarnib and sulforaphane may be a promising therapeutic approach for children with Hutchinson-Gilford progeria syndrome, as it improved the cellular phenotype.

This study constructed a hair follicle-specific expression vector for IGFBP-5 in Inner Mongolia Cashmere goat cells, allowing for future functional genetic analyses and potential use in nuclear transfer.

In a murine model of androgenetic alopecia, this study found that the newly designed IGF-1 biomimetic peptide Ac-GFFY-IGF led to faster and superior hair regrowth compared to minoxidil, suggesting potential for improved human therapies.

This paper proposes that GDNF signaling may enhance skin regeneration and hair follicle formation by influencing dermal fibroblast differentiation, particularly following injury.

This snippet mentions an increase in women seeking surgical hair restoration and subsequently encountering more cases of frontal fibrosing alopecia, but the abstract doesn't contain results or conclusions.

This study explored how long non-coding RNA mediates the effects of FGF5 on the hair follicle development and villus growth of Liaoning cashmere goats.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

In this study, microneedle-assisted human basic fibroblast growth factor therapy was reported to significantly improve hair regeneration in both male and female patients with androgenetic alopecia, alopecia areata, and telogen effluvium, showing greater effectiveness in males.

This study concluded that in female pattern hair loss patients, CGF and i-PRF treatments were more effective than PRP in increasing target area hair count, with i-PRF having the lowest adverse event rate.
