N2 - This paper describes human induced pluripotent stem (iPS) cell-derived neural stem cell (hiPSC-NSC) bundles covered with growth factor-encapsulated amphiphilic chitosan. The hiPSC-NSC bundle is formed by 4-12 hiPSC-NSC microfibers that are made by core-shell hydrogel microfibers encapsulating hiPSC-NSCs. The hiPSC-NSC microfibers can be cultured for over two weeks and induced to differentiate into neurons predominantly. We modified the coating material to make bundle structures that have growth factor enrichment capability (Figure 1). The coating material, amphiphilic chitosan, can release growth factors slowly for a long time, allowing hiPSC-NSCs to survive, grow and differentiate into neural lineages in the bundle structure. We believe that our hiPSC-NSC bundle would be an extremely effective tool for neural transplantation in neurodegenerative diseases such as stroke, spinal cord injury and peripheral nerve injury, because hiPSC-NSCs in the bundle structure have long-term survival ability in vivo.
