This study identified fibroblast growth factor 18 in various components of canine hair follicles and other tissues, but found no significant differences in its presence across seasons, body regions, or sexes in beagle dogs.

In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.

This study concluded that IGF-I receptors are present on hair follicles and sebaceous glands of cashmere and Angora goats, but melatonin receptors are absent.

This study reports that the peptide GPIGS, found in Bacillus sp. M18 conditioned medium, may promote hair growth through the PI-3K/Akt pathway and accelerate hair regrowth in mice.

In this study, injectable platelet-rich fibrin (i-PRF) was found to enhance the proliferative, migratory, and hair-inducing abilities of dermal papilla cells more effectively than platelet-rich plasma through the TGF-β/Smad pathway.

This study found that recombinant human HGF/SF injections altered hair follicle growth cycles and mildly promoted hair elongation in mice, depending on their hair cycle stage.

This study reports that expressed mouse type Ia and type IIa trichocyte keratins were successfully assembled into intermediate filaments in vitro, while also suggesting that disulfide bond cross linking enhances their stability.

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 reports that stimulating sensory neurons with capsaicin and isoflavone increases IGF-I production, promoting hair growth in mice and human volunteers with alopecia.

This review discusses the role of fibroblast growth factors and their receptors in maintaining and repairing epithelial tissues, highlighting their importance in epithelial homeostasis and response to injuries without reporting new clinical results.

This study reports that the recombinant expression vector pcDNA3.1-KK demonstrates specific expression in the skin of newborn mice.

This study observed that epidermal growth factor and fibroblast growth factor have distinct roles in sheep skin, with EGF involved in differentiation and FGF in bulb proliferation and fiber growth.

This study found that FGF18 is crucial for regulating hair follicle rest and growth phases, as its absence in mice leads to a shorter resting phase and rapid hair cycling.

This study found that the NHD domain, but not the PHD domain, of hPygo2 is crucial for Wnt-independent growth of ovarian cancer cells, and identified a key interaction with Treacle protein involved in ribosomal biogenesis.

This study suggests that specific combinations of human type I and II hair keratins, particularly K35-K85 and K36-K81, have distinct in vitro assembly properties that are significant for macrofibril formation.

EGF and FGF signaling stops hair follicle development in mice.

This study found that FGF5-/- rabbits exhibited a significant long hair phenotype by prolonging the anagen phase, suggesting FGF5 acts as a negative regulator of hair growth.

LRIG1 protein affects hair growth by regulating skin receptors, leading to hair loss when overexpressed.

This study suggests that NFIB and STAT5 work together to control cell-specific genetic programs in mammalian tissues, particularly in mammary and hair follicle stem cells.

HGF activator helps convert HGF to its active form, promoting hair growth.

A substance called FGF9 from certain immune cells can trigger new hair growth during wound healing in mice, but humans may not have the same response due to fewer of these cells.

This source provides procedural details without reporting new experimental findings or conclusions.

This study suggests that M2 macrophages play a key role in promoting wound-induced hair neogenesis in mice by producing growth factors like Igf1 and Fgf2.

This study examines various growth factors' roles in hair cell function and suggests insulin-like growth factor may stimulate hair growth, while the precise mechanism of growth inhibition remains unclear.

This study suggests that IGF-1, a component of human placenta hydrolysate, promotes hair growth by increasing the number and size of hair follicles in mice.

In this study, researchers conducted additional IHC staining on equine skin sections and found that collagen type III primarily labels the extracellular matrix, while anti-PDGFR-antibody staining highlights cells with long-shaped processes mainly arranged around hair follicles.

This study found that continuous expression of epidermal growth factor in transgenic mice prevented hair follicles from entering the catagen phase, implicating EGF as a crucial regulator in hair cycle progression.
