This systematic review indicates that a platelet-rich plasma concentration of 1.0 × 10^6 plt/μL may be optimal for tissue regeneration due to sufficient nutrition supply and effective growth factor diffusion in vivo.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This review explores the potential genetic and epigenetic influences on hair whorl patterns and suggests that pattern formation may involve basic physical-chemical laws, although it reports no new experimental findings.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This article discusses the authors’ response to comments on their study about intradermal botulinum toxin's effect on androgenetic alopecia, reporting no new findings.

This study found that stressed dermal fibroblasts significantly increased dopa oxidase activity in melanocytes from hair, skin, and eyes, suggesting the involvement of fibroblast-derived factors like basic Fibroblast Growth Factor.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This letter discusses the variability in platelet-rich plasma preparation for androgenetic alopecia treatment and highlights that different methods yield varied platelet concentrations but not significant differences in growth factor secretion per platelet.

This review updates on the development of liposomal carriers for delivering growth factors to improve tissue regeneration and highlights recent efforts to enhance their stability and retention in tissues.

In this study, researchers demonstrated that treating platelet rich plasma with microsecond pulsed electric fields effectively activates platelets and induces similar or higher growth factor release compared to traditional bovine thrombin, suggesting a potential clinical use that may be more cost-effective and practical.

This study found that prolactin can induce premature catagen in both mouse and human hair follicles and suggests that targeting prolactin and TGF-β receptors may be promising for treating androgenetic alopecia.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This study found that a nanoparticle-in-nanofiber system significantly accelerated wound healing in rats by promoting angiogenesis and tissue regeneration more effectively than a commercial wound dressing.

This study suggests that fibromodulin may regulate transforming growth factor-β activity during scar formation, influencing the transition from fetal scarless repair to adult scar-forming repair in rats.

This review discusses the mechanisms and pathways of FGFR signalling and its roles in development, disorders, and therapeutic targeting, but reports no new clinical results.

This study reports that overexpression of activin in transgenic mice enhances granulation tissue formation during wound healing, highlighting a novel role for activin in cutaneous repair processes.

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.

In this study, researchers found that ginsenoside Re from Panax ginseng increased hair shaft length and duration in mice, comparable to minoxidil, by modulating TGF-β signaling pathways.

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

This study demonstrated that water-soluble peptides from egg yolk, termed "hair growth peptide," stimulated human hair follicle cell growth and improved hair growth in female pattern hair loss.

In this study, researchers developed a new method called Enriched-GF, which enhances growth factor recovery from platelet concentrates through a combination of glass bead activation, freeze-thaw cycling, and calcium stimulation, outperforming conventional methods by providing higher and more consistent yields for regenerative medicine applications.

In this study, transplantation of hair follicle stem cells and nerve growth factor-modified stem cells significantly reduced amyloid deposition and tau hyperphosphorylation in an Alzheimer's disease rat model, suggesting potential as a treatment option.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

This study describes commonly used peptides, proteins, and growth factors in cosmeceuticals and discusses their potential benefits in dermatology, though their long-term effects remain unconfirmed.

This study found that platelet-rich plasma microneedles promoted hair regrowth in mice by facilitating angiogenesis and cell proliferation, showing promise for a minimally invasive hair regeneration treatment.

This study found that Sophora flavescens extract may promote hair growth in mice by inducing earlier hair cycle changes and regulating growth factors in dermal papilla cells.

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.
