A simple method to isolate structurally and chemically intact brain vascular basement membrane for neural regeneration following traumatic brain injury. Biomater Res 2023; 27:2. [PMID: 36635718 PMCID: PMC9837976 DOI: 10.1186/s40824-023-00341-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 01/02/2023] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND The brain vascular basement membrane (brain-VBM) is an important component of the brain extracellular matrix, and the three-dimensional structure of the cerebrovascular network nested with many cell-adhesive proteins may provide guidance for brain tissue regeneration. However, the potential of ability of brain-VBM to promote neural tissue regeneration has not been examined due to the technical difficulty of isolating intact brain-VBM. METHODS The present study developed a simple, effective method to isolate structurally and compositionally intact brain-VBM. Structural and component properties of the brain-VBM were characterized to confirm the technique. Seed cells were cocultured with brain-VBM in vitro to analyze biocompatibility and neurite extension. An experimental rat model of focal traumatic brain injury (TBI) induced by controlled cortical impact were conducted to further test the tissue regeneration ability of brain-VBM. RESULTS Brain-VBM isolated using genipin showed significantly improved mechanical properties, was easy to handle, supported high cell viability, exhibited strong cell adhesive properties, and promoted neurite extension and outgrowth. Further testing of the isolated brain-VBM transplanted at lesion sites in an experimental rat model of focal TBI demonstrated considerable promise for reconstructing a complete blood vessel network that filled in the lesion cavity and promoting repopulation of neural progenitor cells and neurons. CONCLUSION The technique allows isolation of intact brain-VBM as a 3D microvascular scaffold to support brain tissue regeneration following TBI and shows considerable promise for the production of naturally-derived biomaterials for neural tissue engineering.

Abstract
Ischemic brain stroke is caused by blood flow interruption, leading to focal ischemia, neuron death, and motor, sensory, and/or cognitive dysfunctions. Angiogenesis, neovascularization from existing blood vessel, is essential for tissue growth and repair. Proangiogenic therapy for stroke is promising for preventing excess neuron death and improving functional recovery. Vascular endothelial growth factor (VEGF) is a critical factor for angiogenesis by promoting the proliferation, the survival, and the migration of endothelial cells. Here, angiogenic biomaterials to support injured brain regeneration are developed. Porous laminin (LN)-rich sponge (LN-sponge), on which histidine-tagged VEGF (VEGF-Histag) is immobilized via affinity interaction is developed. In an in vivo mouse stroke model, transplanting VEGF-Histag-LN-sponge produces remarkably stronger angiogenic activity than transplanting LN-sponge with soluble VEGF. The findings indicate that using affinity interactions to immobilize VEGF is a practical approach for developing angiogenic biomaterials for regenerating the injured brain.

Abstract
The cerebral cortex is responsible for higher functions of the central nervous system (CNS), such as movement, sensation, and cognition. When the cerebral cortex is severely injured, these functions are irreversibly impaired. Although recent neurobiological studies reveal that the cortex has the potential for regeneration, therapies for functional recovery face some technological obstacles. Biomaterials have been used to evoke regenerative potential and promote regeneration in several tissues, including the CNS. This review presents a brief overview of new therapeutic strategies for cortical regeneration from the perspectives of neurobiology and biomaterial engineering, and discusses a promising technology for evoking the regenerative potential of the cerebral cortex.

Abstract
The integration of microfabrication and biomaterials enables construction of miniaturized 3D microenvironments with biomimetic micro-architectural and functional features to advance cell-based assays for mechanism investigation of physio/pathology and for prediction of drug responses. However, current biomaterials-assisted constructions of miniaturized 3D cellular microenvironments usually involve cells in the microfabrication process, limiting their wide application in most biomedical labs, where expertise and facilities are not readily available. Here we tackle this challenge by developing off-the-shelf microsponge arrays as pre-formed micro-patterned templates which can separate the microfabrication steps from the cell-handling steps and miniaturize the cell-based assays. The microsponge arrays with tailored microarchitectures (e.g. micropillar/well arrays or bifurcated vascular network) could be stored and delivered to distant locations as ready-to-use chips. The highly porous and microscale sponges enabled automatic and uniform loading of cellular niche components (cells, matrices and soluble factors) by simply pipetting, making it accessible to any lab with basic cell culture setups. Meanwhile, the chips containing miniaturized 3D cellular microenvironments with versatile micro-architectural designs could be integrated (i.e. by autoloading and sandwiching) to enable novel 3D cell-based assays (e.g. discrete gradient-based cytotoxicity test and horizontal 3D invasion assay) in an efficient and parallel manner. The off-the-shelf platform based on microsponge array is expected to be widely applicable across multiple disciplines in cell biology, cell/tissue engineering and pharmacological science.
