This study suggests that the dipeptide Pro-Ile has FGF18-like activity, can penetrate model human epidermis, and may have potential as a cosmetic ingredient for skin and hair regulation.

This study found that three sessions of injectable platelet-rich fibrin (i-PRF+) significantly improved hair follicle density, hair volume, and thickness, as well as patient satisfaction in women with female pattern hair loss, with only minor self-limited adverse effects reported.

This study provides a comprehensive platform to explore stem cell interactions regulating hair follicle growth, revealing key signaling pathways in epithelial-mesenchymal interactions using advanced RNA sequencing and transgenic reporters.

This study suggests that transfection with modified KGF-mRNA enhances keratinocyte reepithelialization in wound therapy by temporarily increasing growth factor expression without affecting nuclear DNA.

This review discusses the use of platelet-rich fibrin (PRF) in musculoskeletal, oral, and maxillofacial surgeries and dermatology, but reports no new clinical results; further trials are needed.

This study found that platelet-rich fibrin provides more sustained therapeutic effects than platelet-rich plasma in inhibiting apoptosis and enhancing proliferation and migration of human endometrial stromal cells.

In this study, researchers developed a self-assembling hydrogel called RADA-PDGF2 and found it to accelerate wound closure in a mouse model due to its pro-proliferative and pro-migratory properties, without causing cytotoxicity or immunogenicity.

This study demonstrated that PGF 2α significantly stimulates hair growth in human hair follicles via a receptor-driven mechanism, with a notably stronger response in intermediate follicles than in terminal ones, suggesting potential clinical significance for conditions like alopecia.

In this study, oral administration of ginsenoside Rf from Panax ginseng promoted hair regrowth and increased hair thickness in a mouse model of androgenetic alopecia by enhancing androgen receptor degradation, highlighting its potential for cosmetic and functional food applications.

In this study, iL-PRF injections produced significantly better clinical scores for androgenetic alopecia patients compared to controls, especially in those with more severe baseline conditions.

In this study, researchers found that certain cytokines can significantly down-regulate PDGF expression in dermal papilla cells and follicular keratinocytes, indicating a potential link between PDGF signaling and catagen induction.

In this study, researchers observed that spiral ganglion neurites created more branched networks near FGF-1-coupled beads compared to control beads, highlighting FGF-1's role in hair cell innervation development.

This study suggests that the neuropeptide CGRP may protect against, but not restore, IFNγ-induced collapse of hair follicle immune privilege in alopecia areata.

This review covers the role of proteoglycans in tissue growth and regeneration and highlights several studies on their potential as therapeutic targets, but reports no new clinical results.

In a murine model of androgenetic alopecia, this study found that the newly designed IGF-1 biomimetic peptide Ac-GFFY-IGF led to faster and superior hair regrowth compared to minoxidil, suggesting potential for improved human therapies.

In this study, the addition of A-PRF+ to surgical protocols significantly improved bone healing and implant stability when combined with biomaterials, suggesting it as a viable option for patients concerned about using human- and animal-derived biomaterials.

This study found changes in the PGI2 pathway, especially in gene and protein expression, in diabetic mice, but did not observe PGI2-dependent vasomotor dysfunction.

In this study, researchers reported that a keratinocyte growth factor-Ig fusion protein could specifically detect and localize KGFRs in epithelial tissues, suggesting a method for histochemical detection of growth factor receptors.

This study found that GPC1 is a key regulator of angiogenesis in human dermal microvascular endothelial cells, influenced by factors secreted by keratinocytes, and may be a target for alopecia treatment research.

Progranulin overexpression leads to shorter, thinner hair and increased cell death in mouse hair follicles.

This study found that the peach gene CTG134 mediates auxin-ethylene crosstalk, affecting root hair growth and hormone-regulated processes in plants.

This study found that pretreating concentrated growth factor with a 640 nm laser increased CD34+ stem cell activation and improved hair growth outcomes in androgenetic alopecia patients compared to non-pretreated CGF.

This study found that Pdgfα signaling is crucial for maintaining dermal adipose tissue in mice by initiating dermal adipocyte stem cell proliferation, with implications for age-related skin defects.

In this study, researchers found that IGFBP‐rP1 levels were lower in individuals with androgenic alopecia compared to healthy controls, and subcutaneous injection of IGFBP‐rP1 showed potential in slowing hair loss progression in a mouse model by affecting the hair cycle transition.

This study reported that platelet-rich fibrin (iPRF) therapy may improve scalp health and hair appearance in women, showing beneficial changes in scalp hydration, redness, oiliness, and hair density, thickness, and loss.

The study suggests that variability in platelet-derived growth factors in PRP is influenced by both patient-to-patient differences and the devices used for PRP preparation, contributing to inconsistent clinical outcomes in hair loss treatments.

This study suggests that the Grasp protein may play a role in regulating skin homeostasis following UVB exposure by influencing p53-mediated apoptotic responses in mice.

This study found that GPC1 is a significant regulator of angiogenesis in human dermal microvascular endothelial cells, suggesting its potential as a target for alopecia research.

This study identified mutations in the FGF5 gene as a cause of extreme eyelash growth in Pakistani families, highlighting a potential target for regulating eyelash growth.

This review explains the biology and preparation of platelet-rich plasma and discusses its clinical applications in plastic surgery, but reports no new findings.
