Glycopeptide microneedles triggering the ECM process to promote fibroblast viability for anti-aging treatments
Skin anti-aging remains challenging due to the cumulative detrimental effects within the intricate microenvironment. Here, we present glycopeptide hydrogel (γ-PGA/HA) microneedle patches composed of poly (γ-glutamic acid) and hyaluronic acid as a potential solution. These microneedles aim to effectively penetrate the skin barrier while remodeling extracellular matrix to regulate the skin microenvironment. To align with clinical requirements, the functional properties of microenvironment regulation materials are characterized by testing the water absorption and retention, redox balance, and inflammatory microenvironment regulation ability. The γ-PGA/HA exhibited remarkable moisturizing, biocompatibility, fibroblast viability promotion, ROS consumption, and TNF-α inhibiting effects. Histological analysis provides empirical evidence supporting the functional efficacy of the microneedle, thus validating the anti-skin-aging potential of a model that mimics natural aging processes. Therefore, γ-PGA/HA holds promise for regulating the skin microenvironment, offering potential applications in skin aging treatments.
期刊介绍：
Biomaterials Advances, previously known as Materials Science and Engineering: C-Materials for Biological Applications (P-ISSN: 0928-4931, E-ISSN: 1873-0191). Includes topics at the interface of the biomedical sciences and materials engineering. These topics include:
• Bioinspired and biomimetic materials for medical applications
• Materials of biological origin for medical applications
• Materials for "active" medical applications
• Self-assembling and self-healing materials for medical applications
• "Smart" (i.e., stimulus-response) materials for medical applications
• Ceramic, metallic, polymeric, and composite materials for medical applications
• Materials for in vivo sensing
• Materials for in vivo imaging
• Materials for delivery of pharmacologic agents and vaccines
• Novel approaches for characterizing and modeling materials for medical applications
Manuscripts on biological topics without a materials science component, or manuscripts on materials science without biological applications, will not be considered for publication in Materials Science and Engineering C. New submissions are first assessed for language, scope and originality (plagiarism check) and can be desk rejected before review if they need English language improvements, are out of scope or present excessive duplication with published sources.
Biomaterials Advances sits within Elsevier''s biomaterials science portfolio alongside Biomaterials, Materials Today Bio and Biomaterials and Biosystems. As part of the broader Materials Today family, Biomaterials Advances offers authors rigorous peer review, rapid decisions, and high visibility. We look forward to receiving your submissions!
