Fig. 5: CAR-T cell pharmacokinetics and B cell persistence.

A CAR-T cell number in peripheral blood mononuclear cells (PBMCs). Absolute counts of CAR-T cells in peripheral blood were measured using flow cytometry. B Presence of CAR-expressing T cells among lymphocytes as quantified by flow cytometry. C Percentage of CD19+ cells among lymphocytes as quantified by flow cytometry.
