This video demonstrates the reprogramming of peripheral blood mononuclear cells (PBMNCs) into induced neural stem cells (iNSCs) using Sendai virus. Sendai virus is a non-integrating virus that offers an efficient and safe vehicle for reprogramming cells.

Protocol

1. Reprogramming of PBMNCs to iNSCs by SeV Infection

1. Preparation of Solution and Culture Medium
   1. Prepare a poly-D-lysine (PDL) stock solution by dissolving 100 mg of PDL with 100 mL of H₂O to a concentration of 1 mg/mL. Store at -20 °C in 1 mL aliquots.
   2. Prepare an insulin stock solution by dissolving 100 mg of insulin in 20 mL of 0.01 N HCl to a concentration of 5 mg/mL. Store at -20 °C in 1 mL aliquots.
   3. To prepare 200 mL of iNSC basal medium, combine 96 mL of DMEM-F12 and 96 mL of basic medium (Table of Materials) with 2 mL of 100x glutamine stock solu....
