This paper introduces Concentration Growth Factor (CGF) as a potential treatment for androgenetic alopecia, but reports no clinical findings on its effectiveness in promoting hair growth.

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 found that applying ferrous ferric chloride skin lotions to newborn mice stimulated skin cell proliferation and differentiation, increased hair growth, and inhibited alopecia-related hair loss.

This study found that PGF 2α receptors were predominantly present in the inner root sheath of the bulb and stem of human eyelashes during the anagen phase.

FGF9 from certain cells can trigger new hair growth during wound healing, but humans have fewer of these cells, which may limit hair regrowth.

This study found that the loss of a functional hr gene in mice leads to premature and abnormal hair follicle regression, disrupting normal hair cycling and architecture.

Keratinocyte growth factor significantly alters skin and tissue development.

This study found that loss of the folliculin protein delays transferrin receptor recycling, leading to iron deficiency and suggesting a role in the mechanisms of Birt-Hogg-Dubé syndrome.

In this study, the use of rb‐bFGF in hair transplantation significantly increased follicle survival, reduced hair loss, improved patient satisfaction, and decreased complications compared to controls, in patients with androgenetic alopecia over a 12-month period.

In this study, researchers observed distinct morphological differences in hair follicles of mutant mouse genotypes, influenced by the expression levels of keratin2-6g, which is essential for proper hair follicle development.

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.

This study reported that Tomorrowlabs HIF strengthening factor [HSF] hair restoration technology significantly improved hair thickness, density, shine, and elasticity, while reducing hair loss by an average of 66.8% and enhancing hair growth by up to 32.5% in subjects with androgenic alopecia over nine months.

In this study, transient transfection of the HIF-1α gene into fibroblasts led to increased VEGF expression, which may enhance the growth and anagen phase of human hair follicles in vitro.

In this study, the researchers observed that the expression of certain growth factors and their receptors increases with gestational age, implying a role in skin development, structure maintenance, and wound healing.

This study found that growth factor cocktail treatment including FGF9, combined with microneedling, significantly improved hair density in androgenetic alopecia patients compared to treatment with regular GFC or normal saline.

This study concluded that using human umbilical cord blood mononuclear cells transfected with VEGF and FGF2 genes enhances skin wound healing in rats, demonstrating greater wound revascularization compared to controls.

In this study, the researchers identified LHX2 as a specific marker for hair follicle placodes, differentiating them from eccrine sweat gland placodes through double immunofluorescence staining.

This study found that recombinant human ADM2 treatment inhibited cell proliferation and induced apoptosis in human hair follicles, contrasting with the previously documented pro-proliferative and anti-apoptotic functions of ADM2.

This study found that combining Concentrated Growth Factors with Follicular Unit Extraction significantly improved hair density and terminal hair ratio in men with androgenetic alopecia compared to FUE alone.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This study demonstrated that FGF5s acts as an inhibitor of FGF5 in regulating hair growth cycles in cashmere goat dermal papilla cells.

In this study, researchers characterized the FGF5 gene in Chinese Merino sheep, identified a new mRNA splicing variant, FGF5S, and noted its restricted expression in the brain, spleen, and skin.

This study demonstrated that fibrin hydrogels support skin-derived precursors in hair follicle neogenesis in mice, with new hair growth and regeneration of blood vessels and sebaceous glands observed.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

This study found that the manual hair transplantation method HFE may offer better precision and cosmetically satisfying results with minimal tissue trauma for treating androgenetic alopecia in men.

In this study, a topical formulation with compounds from the monoterpenoid family significantly improved hair growth indicators like anagen:telogen ratio, hair fall, and visual hair density in men and women with pattern hair loss.

In this study, topical application of fibroblast growth factors was found to promote hair growth by inducing and prolonging the anagen phase in telogenic C57BL/6 mice, suggesting potential as hair growth-promoting agents.

This study found that HIF-P4H-2 function in FoxD1-lineage cells is crucial for normal hair follicle development and homeostasis in mice, implicating disrupted HIF, TGF-β, and Notch signaling pathways in associated defects.
