    Single Cell and Spatial Sequencing Define Processes by Which Keratinocytes and Fibroblasts Amplify Inflammatory Responses in Psoriasis

    The authors demonstrated, using a combination of single cell and spatial RNA sequencing, IL-36 dependent amplification of IL-17A and TNF inflammatory responses in the absence of neutrophil proteases, which primarily occurred within the supraspinous layer of the psoriatic epidermis.

    Abstract

    3D-Bioprinted Biomimetic Multilayer Implants Comprising Microfragmented Adipose Extracellular Matrix and Cells Improve Wound Healing in a Murine Model of Full-Thickness Skin Defects

    In vitro, the microfragmented adipose ECM composite demonstrated biocompatibility, printability, and fidelity and could support cell adhesion. In a full-thickness skin defect model in nude mice, cells encapsulated in the implant survived and participated in wound repair after implantation.

    Defective Extracellular Matrix Remodeling in Brown Adipose Tissue Is Associated with Fibro-Inflammation and Reduced Diet-Induced Thermogenesis

    Researchers showed that a time course of high-fat diet feeding progressively impaired diet-induced thermogenesis concomitantly with the development of fibro-inflammation in brown adipose tissue.

    Bioactivity of Human Adult Stem Cells and Functional Relevance of Stem Cell-Derived Extracellular Matrix in Chondrogenesis

    Adult stem/progenitor cells were isolated from human adipose, bone marrow, and articular cartilage, and cultured for 14 days in monolayer in mesenchymal stromal cell–ECM induction medium to allow matrix deposition and cell sheet formation.

    Osteomatrix as a Personalized 3D Tissue-Specific Invasion Test-Bed for Oral Carcinoma

    The ECM was obtained from caprine bone by a combination of demineralization, delipidation and decellularization (D3) techniques. The bone D3-derived ECM tissue was characterized for analyzing the effective removal of cells, minerals, and lipids with an intact structure and chemical composition.

    Evaluation of Surgical Fixation Methods for the Implantation of Melt Electrowriting-Reinforced Hyaluronic Acid Hydrogel Composites in Porcine Cartilage Defects

    Acellular melt electrowriting (MEW)-norbornene-modified hyaluronic acid (NorHA) composites or MEW-NorHA composites with encapsulated porcine MSCs and precultured for 28 days were implanted in full-thickness cartilage defects in porcine knees.
