In our acute lymphoblastic leukemia (ALL) model (Figure 2A), we engrafted 0.5 × 106 SUP-B15 ALL cells intravenously (i.v.)into NSG mice, treated with 1 × 106 CD19-dex-CAR or untreated CD19-CAR T cells, and evaluated tumor growth and mouse survival. The gene discussed is CD19; the disease is acute lymphoblastic leukemia.
