[...]... addition of water and are crosslinked There are three main biomaterials belonging to the hydrogel family that have been used to provide a scaffold for axonal regeneration: (1) agarose, (2) alginate, and (3) collagen 8 ANJANA JAIN AND RAVI V BELLAMKONDA 1.2.1.1 Agarose as a Scaffolding Material Agarose, which is a thermoreversible copolymer of 1,4-linked 3,6-anhydro-α-L-galactose and 1,3-linked β-galactose,... University, Houston, TX Professor of Biochemistry and Molecular Biology University of Texas Medical Branch, Galveston, TX President, the Texas Alliance for NanoHealth, Houston, TX I Cell-based Therapeutics 1 Nano- and Micro-Technology to Spatially and Temporally Control Proteins for Neural Regeneration Anjana Jain and Ravi V Bellamkonda WHC Department of Biomedical Engineering, Georgia Institute of Technology/Emory... Georgia 3033 2-0 535 1.1 INTRODUCTION Nano- and micro-technologies in the field of neural tissue engineering have implications in the pursuit of spatial and temporal control of protein and sugar cues at the site of injury and in the control over cellular response to these cues to promote regeneration and healing The nervous system consists of two main components that are relevant from a regeneration and tissue... clinically autografts are the state-of-the-art to regenerate nerves in the PNS, they are not the ideal solution because the donor supply is limited and obtaining a nerve graft from the patient means that the donor site has been denervated Therefore, there is a great need to find a tissue engineered therapeutic solution to regenerate axons in the CNS and the PNS 1.1.2 Nano- and Micro-scale Strategies to Promote... part, Cell-based therapeutics; covers the merger of cells with micro- and nanosystems for applications in regenerative medicine spanning the development of novel nanobiomaterials, methods of tissue assembly with control over tissue microarchitecture, and methods to specify patterns of protein distribution that vary on the micro- and nanoscale for application in tissue regeneration (A), and therapeutic. .. axonal growth in a specific direction NANO- AND MICRO-TECHNOLOGY 9 1.2.2.1 Alginate as a Scaffolding Material Alginate is another scaffold material, similar to agarose, which can be utilized to control proteins spatially in order to influence axonal regeneration Alginate can be found in brown seaweed and is a copolymer formed from α-L-glucoronic acid and β-D-mannuronic acid The studies that have used...
