This study found that in patients with elevated fibrinogen levels undergoing revision rhinoplasty, PDRN decreased M1 cytokines and increased M2 cytokines, potentially offering a new therapeutic approach, but further research is needed to understand its mechanisms and effects fully.

This review discusses the potential of bioprinting technology in cosmetology, particularly for improving skin functions like pigmentation restoration and hair follicle development, but reports no new clinical findings.

This study found that human hair follicle dermal papilla cells and keratinocytes self-assembled differently in 3D spheroid co-cultures, providing insights into cell distribution and organogenesis during skin regeneration.

This study found that the polyurethane-cellulose acetate scaffold containing plasma rich in growth factors enhanced gene expression linked to wound healing compared to controls.

This study developed 3D micropatterns with magnesium silicate nanospheres that mimic vessels and hair follicles for potential use in skin regeneration by reconstructing vasculature and promoting hair growth.

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 pilot study, combined platelet-rich plasma therapies showed potential benefits for improving skin elasticity and vascular network density in morphea patients, but the small sample size limits definitive conclusions.

This review outlines the current state of freeze-dried platelet-rich plasma (FD-PRP) research, emphasizing its use in wound healing, lumbar fusion, knee conditions, and dentistry, but reports no new clinical findings.

This study found that a chitosan/PDRN nanopolyplex significantly improved diabetic wound healing in rats by enhancing cell proliferation, migration, and antimicrobial activities, suggesting its potential as a therapeutic product.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This review discusses the role of Prostaglandin D2 and its synthase in androgenetic alopecia but reports no new clinical findings, suggesting pathways for future therapeutic development.

This article discusses tools for measuring hair density in donor areas to guide hair transplant surgery and reports no new clinical results; the authors emphasize the role of digital imaging in achieving consistent outcomes.

This study introduces a new biomimetic double wound mask designed to promote scarless healing by coordinating multiple biological pathways and providing enhanced protection and nourishment to wounds.

This study investigated how different 3D bioprinted scaffold structures affect immune responses and hair growth in mice, finding that moderate immune response induced by certain structures stimulates hair growth, while excessive immune response can hinder hair follicle development.

This study developed a 3D skin model with immune and endothelial cells, which may enhance understanding of skin biology and diseases due to its closer approximation to native skin.

This study found that forming inclusion complexes of DPCP with HPβCD using the 3D ground mixture method enhances its anti-inflammatory activity at lower doses compared to complexes with β-CD.

This study introduced a novel 3D co-culture system that effectively mimics in vivo extracellular matrix dynamics, supporting hair follicle biology research and providing a robust platform for evaluating hair loss treatments through enhanced epithelial-mesenchymal interactions.

This study found that alginate spheres maintain dermal papilla cells in a dormant state with increased trichogenecity, suggesting potential benefits for cell therapy in androgenic alopecia.

This study demonstrates the use of microscopy-guided laser ablation to create a highly structured 3D hydrogel-based organotypic skin model with folliculoid structures, potentially useful for studying hair follicle development or bioactive substance screening.

This letter discusses three plasmacytoid dendritic cell-related parameters that may help differentiate lupus alopecia from lichen planopilaris, but it reports no new study results.

This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

This study suggests that Annexin A2 isoform 2 might play a role in regulating the proliferation and growth of dermal papilla cells, potentially impacting the hair follicle growth cycle.

This study found that canine adipose-derived mesenchymal stem cell-derived dermal papilla-like tissues promoted new hair follicle formation and increased vascularization in mice, suggesting potential for hair regeneration.

This study found that proton minibeam radiotherapy demonstrated a potential tissue-sparing effect in epidermis models by spatially confining DNA damage, suggesting reduced side effects in radiotherapy.

In this randomized, double-blind, placebo-controlled trial, researchers found that a multi-targeted cosmetic formulation containing TrinogeniX™ significantly increased hair density and thickness in individuals with androgenetic alopecia without adverse effects, suggesting it as a potential safe and effective treatment option.

The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.

In this study, combining stromal cells and PRP resulted in a significantly higher cell count and volume than using a saline group, suggesting increased potential efficiency; however, clinical outcomes need further evaluation.
