Figure Lengend Snippet: NPC-ABS/FDS mediated deep chemotherapy and induced immune activation. ( A , B ) Confocal microscopy images in 3D tumor spheres after treated with different groups (a. NPC-FCS, b. NPC-FCS+NPC-AEAA-SLN, c. NPC-FCS+BAE-Sol, d. NPC-FCS+ABS, and e. NPC-ABS/FCS. Z-axis scan spacing = 10 μm. BAE = 2 μg/mL in A and BAE = 5 μg/mL in B, respectively; the magnification was 10×). ( C ) Representative photomicrographs of tumor biopsies treated with different groups (a. normal saline, b. NPC-AEAA-SLN, c. BAE-SLN, d. ABS, and e. NPC-ABS). Tumor blood vessels were labeled with FITC-CD31; the magnification was 20×). Relative expression quantity of immune-associated cells in mouse tumors after administration of different preparations of ( D ) CD4 + T cells, ( E ) CD8 + T cells, and ( F ) Tregs (a. normal saline, b. NPC-AEAA-SLN, c. BAE-SLN, d. ABS, and e. NPC-ABS. Mean ± SD, n = 3. ** p < 0.01, *** p < 0.001. Blue color represented positive cells; the magnification was 10×).
