Figure 4. ApEn-NK specifically binds adherent TNBC cells with high capacity.

Figure 4.

(A) Scheme of cell binding assays. (B-E) ApEn-NK specifically bound TNBC cells (HCC1937 and MDA-MB-231) with higher affinity compared to parental NK-92 cells. (F, G) Similar background baseline binding to off-target non-TNBC cells (MCF-7) was detected in cultures exposed to ApEn-NK or parental NK-92 cells. Scale bar: 100 μm. All experiments were repeated ≥ 3 times. Representative results are presented. Data are shown as mean ± S.D. ***: P<0.001 (Student’s t-test, two-tailed). NS: not significant.
