Transwell inserts were added and CSPG4‐CAR‐T or control T cells were seeded therein. T cells were allowed to migrate through inserts for 5 h. Afterward, inserts were removed and media was collected for flow cytometry. (c) Migration of CSPG4‐CAR‐T or control T cells toward U87 or U87 RANTES‐IL‐15 cultured for 24 or 48 h was evaluated by flow cytometry ( n = 3).

(b) Human fibroblasts were transduced with LV‐RANTES‐IL‐15‐GFP, LV‐Sox2, and LV‐rtTA in succession. Reprogramming and primary hiNeuroS formation were initiated by switching to NSC growth media supplemented with growth factors and tetracycline. Three rounds of cell cluster selection were performed by serial seeding on laminin‐coated plates. After each round of selection, nonadhering cells were collected and expanded to yield secondary hiNeuroS.
