Oxygen Supply of Islets of Langerhans by Photosynthetically Active Microalgae in Bioprinted Co‐Cultures Maintains Their Function in a Hypoxic Environment

Advanced Healthcare Materials, EarlyView.
This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Opinion: Gavage Administration of MXene as a Route‐Specific Alternative to Intravenous Injection into the Bloodstream of Laboratory Animals for Reducing Systemic Nanotoxicity Risks in Immunosuppression and Post‐Transplantation Models with Bile Acid Modification

Advanced Healthcare Materials, EarlyView.
Recent studies reported immunosuppressive properties of specific MXene nanomaterials. Their intravenous injection into the bloodstream of laboratory animals has been a common delivery method to suppress systemic inflammation and prevent transplant rejection.
