    Super-Enhancer-Driven MLX Mediates Redox Balance Maintenance via SLC7A11 in Osteosarcoma

    Researchers found that Max-like protein X (MLX), a member of the Myc-MLX network, was driven by super-enhancers. Upregulation of MLX predicted a poor prognosis in osteosarcoma.

    Plasma Fibrin Membranes Loaded with Bone Marrow Mesenchymal Stem Cells and Corneal Epithelial Cells Promote Corneal Injury Healing via Attenuating Inflammation and Fibrosis after Corneal Burns

    Bone marrow MSCs were induced to differentiate into corneal epithelial cells via direct contact co-culture, and platelet-poor plasma was used to prepare fibrin gels, which were compressed to remove excess liquid and then lyophilized to obtain plasma fibrin membrane.

    Combination of Human Platelet Lysate and 3D Gelatin Scaffolds to Enhance Osteogenic Differentiation of Human Amniotic Fluid Derived Mesenchymal Stem Cells

    Scientists compared the effectiveness and safety of different culture supplements, either fetal bovine serum or human platelet lysate, on the osteoblastic differentiation potential of MSCs derived from human amniotic fluid under a 3D gelatin scaffold.
