Figure Lengend Snippet: Activation markers of CD56 bright CD16 bright iPSC-NK cells. (A) The Immunocytochemistry data showed positive expression of the activation markers such as SH2D1A, NKG2D, CD107a, and inhibitory markers, KIR2DL and CD94 upon coculture with (i) CHLA-02-ATRT or (ii) CHLA-05-ATRT. (B) (i) The percentage expression of the activation markers, NKG2D and NKp46, in iPSC-NK cells before and after coculture was performed using flow cytometry. (ii) The relative gene expression of NK cell markers, including NKG2D, CD107a, NKp46, CD16a and CD56 after IL-15 treatment was also measured. KIR2DL1, killer cell immunoglobulin-like receptor 2DL1; SH2D1A, SH2 domain-containing protein 1A; NKG2D, NKG2-D type II integral membrane protein. The scale bar in (A) represents 100 μm, which corresponds to a 20x magnification. The statistically significant data are represented with “*”, “**”, and “***” for p- values <0.05, <0.01, and <0.001, respectively.
Article Snippet: In this study, two distinct types of ATRT cell lines, namely CHLA-05-ATRT (ATCC® CRL-3037TM, ATCC) and CHLA-02-ATRT (ATCC® CRL-3020TM, ATCC), were used to test the cytotoxic effect of iPSC-NK cells.
