Meanwhile, as shown in Figure 7C, real-time photographs demonstrated that B7-H3Bi-armed ATC, but not unarmed ATC, aggregated with B7-H3-positive, but not B7-H3-negative primary tumor cells, clustering around the edge of targeting cell bulk which showed the specific lysis of B7-H3Bi-armed ATC. Here, CD276 is linked to neoplasm.
