L. casei 03 inhibited BMECs apoptosis induced by E. coli. (A) Apoptosis was evaluated by measuring Annexin/PI fluorescent staining. Green, Annexin V-positive; Red, PI-positive; DIC, ordinary light; scale bar: 200 μm. (B) The apoptotic rate was quantified by counting the green-positive cells. Groups with different letters above the bar indicate significant differences (P < 0.05). These same conventions were used in subsequent figures
