Fig. 2. The anti-proliferation effect of CD40mAb released from PLLA-PDA-CD40mAb scaffolds for 24 h towards MDA-MB-231 cells. (a) Cell viability of MDA-MB-231. (b) The relative gene expressions of Bax and Bcl-2 of MDA-MB-231 cells (data are represented as fold changes normalized by cells cultured in cell medium). (c) Flow cytometry assay (FCA) for MDA-MB-231 cell apoptosis. Control: cells seeding onto the plate (compared with the PLLA group; *p < 0.05).
