Special Issue Information

Dear Colleagues,

The purpose of this Special Issue is to focus on the role of the extracellular matrix (ECM) and basement membrane in skin reconstruction and regeneration, with particular attention to their biological and clinical relevance in restoring damaged or diseased skin. In recent years, the ECM has come to be recognized not simply as a structural framework but as an active regulator of cell behavior, immune responses and tissue remodeling. Together with the basement membrane, it plays a central role in maintaining skin integrity and guiding the complex process of repair following injury, surgery or chronic disease. At the same time, advances in acellular dermal matrices and other ECM-based biomaterials have expanded therapeutic options for a wide range of clinical problems, including complex wounds, burns, radiation injury, chronic ulcers and pathological scarring. These developments raise important questions regarding how native ECM architecture can be preserved or reconstructed in ways that support true tissue regeneration rather than temporary defect coverage. This Special Issue welcomes original research articles and review papers that address, among others, the structural and functional roles of dermal ECM and basement membrane in skin repair; ECM remodeling in acute and chronic wound healing; fibrosis, hypertrophic scars and keloids viewed from an ECM perspective; clinical and experimental use of acellular dermal matrices and biologic scaffolds; the influence of mechanical forces and ECM on skin regeneration Interactions between ECM and the immune system during cutaneous repair; translational and clinical studies of ECM-based regenerative therapies as well as regulatory and safety issues related to human tissue-derived ECM products.

By bringing together basic science, tissue engineering and clinical reconstruction, this Special Issue aims to provide a focused and practical discussion for advancing ECM-centered approaches in cutaneous regenerative medicine.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Injectable skin boosters currently in use mainly provide short-lived volumization or depend on inflammation-mediated collagen stimulation, raising concerns regarding durability and safety. Injectable particulate human acellular dermal matrix (phADM) is a biologically derived extracellular matrix scaffold designed to support constructive dermis remodeling. This randomized, split-face, double-blinded clinical trial evaluated the efficacy of phADM as a facial skin booster in 20 adults with moderate cheek roughness. phADM was injected on one facial side, with hyaluronic acid serving as the contralateral control. Multiple skin parameters were assessed over 20 weeks using validated imaging and biophysical instruments. Mechanistic validation was conducted using complementary in vitro, ex vivo human skin, and in vivo rat models. Clinically, the phADM-treated side demonstrated greater improvements in skin density, volume, elasticity, wrinkle depth, pore area, hydration, and barrier-related parameters at multiple time points compared with HA. In ex vivo human skin, phADM showed homogeneous dermal distribution and preservation of extracellular matrix architecture, along with restoration of basement membrane-associated proteins following UVB irradiation. In vivo rat studies revealed fibroblast infiltration and localized neocollagenesis within the implanted matrix. In vitro assays further indicated enhanced fibroblast proliferation and extracellular matrix synthesis, increased hyaluronan production, suppression of pro-inflammatory cytokines in activated macrophages, and downregulation of melanogenesis-related genes in melanoma cells. No serious adverse events were observed during the clinical study. These findings indicate that phADM functions as a restorative skin booster that promotes durable dermis remodeling and functional rejuvenation with a favorable safety profile. Full article
