Fig. 5: Dynamics of T-cell recruitment and tumoroid killing for effective versus non-effective bsAbs.

A Maximum projection images showing T-cell recruitment to the tumoroid and tumor killing with 12 h intervals from day 2 to day 5 after exposure of collagen embedded BT474 tumoroids to a mixture of T-cells and 0.1 μg/mL of the indicated bsAbs. Blue, tumor nuclei; green, T-cells; red, PI. Bar = 100 μm. B Quantification of time-lapse image data with 1-h intervals as shown in A. Green line represents the number of T-cells localized in the tumoroid. Red line represents the percentage of PI positive tumor cells, indicating loss of viability. Mean and SEM of three tumoroids is shown.
