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.

In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.

Improving knowledge and practices in animal fibre production is crucial to meet market demands and potentially revive natural fibres.

This abstract discusses the challenges faced by the wool industry in Baluchistan, Pakistan, highlighting the need for improved education and technical resources for wool shearing and processing, but reports no new research results.

This review discusses selection signatures and selective sweeps in fiber-producing animals and recommends further genomic investigations to identify genes related to important fiber traits, without providing new results.

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 describes the development of polyamide 6 composite fibers with amber filler, finding them suitable for use in medical textiles such as compression garments due to their biocompatibility with skin cells.

This review discusses the biology of hair follicles across various species and their role in fiber quality, but reports no new experimental findings.

In this study, researchers used transcriptome sequencing to identify 1543 differentially expressed genes between cashmere and normal goats, implicating several signaling pathways and key regulators in the distinct gene expression profiles linked to cashmere fiber production, which advances understanding of cashmere goat genetics.

This study reveals that long non-coding RNAs influence cashmere fiber traits in goats by interacting with target genes involved in pathways affecting fiber diameter and color.

This review discusses studies on hair growth and protein synthesis in hair follicles, highlighting the differing responses of mohair and cashmere goat follicles to signaling molecules, biotin, and amino acids, but contains no new results.

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 treatment with mercuric acetate modifies the elastic properties of Lincoln wool fibers more rapidly than human hair, explaining the enhanced unshrinkable quality of wool under certain conditions.

This study found that melatonin treatment significantly increased wool production and hair follicle activity in German angora rabbits, with larger effects seen in defleeced animals and those treated in July.

This study found that a 3D Matrigel culture technique for dermal papilla cell spheroids can enhance hair follicle inductivity and induce hair-like fiber differentiation in vitro, even with high-passage cells.

This study investigated hair fibre growth in Angora and Cashmere goats, finding differences in growth rates and seasonal dependencies, and examined the effects of prolactin and melatonin on protein deposition in hair follicles.

This study found that melatonin treatment improved cashmere production for one cycle in cashmere goats, enhancing fiber quality and follicle activity, but had no effects in the subsequent cycle.

This study found that melatonin treatment in adult cashmere goats increased cashmere yield and improved fibre quality without negatively affecting the hair follicle development or cashmere production in their offspring.

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 review found limited but suggestive evidence that Calcium Hydroxylapatite may promote skin regeneration through increased collagen production, cell proliferation, and angiogenesis, although most studies had methodological limitations.

This review examines recent advancements in electrospun nanofibers for wound healing applications, but reports no new experimental results, highlighting their potential in sutures, dressings, and skin regeneration.

This study found that adult dermal papilla cells guided high-passage adult keratinocytes to produce new hair fibers, suggesting potential for large-scale hair follicle bioengineering.

This review discusses the use of derma rollers for cosmetic purposes and their potential in transdermal drug delivery by summarizing evidence on their design, efficacy, safety, and concerns from preclinical and clinical reports.

This study found that cysteine and arginine are crucial for hair growth in hair follicles, with cysteine affecting hair fibre diameter and arginine involved in protein incorporation and energy metabolism.

This article examines the terminal to vellus transition in androgenetic alopecia through cellular and developmental mechanisms, discussing challenges and knowledge gaps without presenting new clinical findings.

This study concluded that epidermal growth factor may induce a 'catagen-like' phase in human hair follicles by disrupting normal cellular proliferation and migration patterns.

In this mouse study, researchers reported that sequential monopolar-bipolar radiofrequency irradiation significantly improved skin quality by increasing collagen density, elastin fiber expression, and fibroblast differentiation more than monopolar RF treatment alone.

This article reviews drug influences on hair growth without visible hair loss, noting several mechanisms that require detailed examination, but reports no new clinical results.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.
