Cytotoxic Responses against Regenerated C1/C1 T Cells Is Limited to the KIR2DL1+ NK Cell Subsets Isolated from a C1/C2 Donor
(A) Flow-cytometric profiles of KIR2DL1 and KIR2DL3 in NK cells isolated from donor Hetero-1 after sorting by magnetic beads. KIR2DL1− cells (R1/R4) were enriched by negative selection (depletion of KIR2DL1+ cells), whereas KIR2DL1+ (R2/R3) cells were enriched by positive selection.
(B and C) Six-hour cytotoxicity assays of NK cells isolated from donor Hetero-1 against Homo-A iPSC-TCs. Results are presented as mean ± SD from three independent experiments. ∗p < 0.05, ∗∗p < 0.01, Student's t test.
