This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

In this study, melatonin implants advanced and synchronized spring hair growth in goats by initiating fiber growth earlier than in untreated goats, with associated suppression of normal prolactin rise.

This study found that seasonal changes significantly affected hair follicle activity and fibre growth in Merghoz goats, with variations seen in feed intake and growth patterns across different seasons.

This study found that epidermal growth factor significantly reduced fibre growth in cultured Tukidale and Romney hair follicles, while cortisol had no effect on follicle growth.

This study found that IL-1 alpha inhibits the growth of cultured human hair follicles and hair fibers, suggesting a potential role in inflammatory hair loss conditions like alopecia areata.

This study found that relatively low concentrations of 1,25(OH)2D3 stimulated human hair follicle and fiber growth, while higher concentrations inhibited growth in a whole-organ culture system.

This study found that administering melatonin to ferrets can advance the timing of fur growth and reproductive cycles influenced by daylength and hormonal control.

This study's simulations suggest that biomechanical factors, like follicle geometry and tissue stiffness, are likely significant in hair fiber protrusion, providing a framework for future experimental validation.

This article reviews how photoperiod, melatonin, and prolactin influence moult timing in mammals, focusing on cashmere goats, but reports no new experimental findings.

This study observed that key signaling events controlling hair growth in ferret follicles occur between 0 and 4 days after melatonin implantation, highlighting distinct processes in follicular regeneration and fibre growth.

This study developed a multifunctional core-shell fiber dressing that preserves platelet-rich plasma for 180 days, facilitating sustained growth factor release and improved wound healing.

Merkel cells likely attract sensory nerve fibers.

This study found that the maximum infrared temperature of laser-irradiated hair depends on melanin type, with eumelanin-rich hair reaching higher temperatures than pheomelanin-containing hair.

This review highlights the critical role of microRNAs in regulating hair follicle biology, significantly impacting wool and cashmere development by modulating gene expression and signaling pathways in sheep and goats.

This study observed that mice with a Cx43 mutation exhibited slower and asynchronous hair regrowth with severe cuticle weathering, mimicking aspects of hair phenotype in some ODDD patients.

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 found that non-pigmented hair follicles have significantly lower expression of nucleotide excision repair genes, which may be associated with reduced melanin production capacity in these follicles.

This study suggests that the methylation degree of HOXC8 exon 1 in the hair follicle may influence cashmere fiber growth in Liaoning cashmere goats.

This review highlights the significance of animal fibers, examining the molecular mechanisms influencing hair follicle development and their impact on fiber quality and quantity, with a focus on studies involving Angora and cashmere goats.

This study found that cultured papilla cells can induce follicle formation and hair growth when combined with different epidermal and dermal cells, highlighting their powerful inductive properties and potential for dermatological applications.

This study found that repeated immunization against melatonin in Australian feral goats temporarily increased cashmere production and altered growth cycles, but these effects diminished after the first year.

KAP9.2 and Hoxc13 genes are important for cashmere growth and vary in activity during different stages.

This study found that exposure to red LED light may improve fibre quality and hair follicle development in Angora rabbits, potentially due to increased melatonin secretion.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

Acankoreoside J from Acanthopanax koreanum may help promote hair growth.

This study found that disrupting the PRL gene in mice alters the timing of hair cycling events, causing earlier molts and changes in hair characteristics, particularly affecting female mice more significantly.

This study established that cryopreservation methods can maintain the pluripotency and hair growth potential of hair follicle-associated pluripotent stem cells, enabling potential applications in regenerative medicine and hair transplantation.

This study mapped the genome-wide epigenetic landscape in secondary hair follicle stem cells of goats, revealing distinct histone modification signatures associated with cashmere fiber cycling during different stages of hair growth.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.
