Fig. 5From: Metal ion-responsive nanocarrier derived from phosphonated calix[4]arenes for delivering dauricine specifically to sites of brain injury in a mouse model of intracerebral hemorrhagea Flow cytometry of SH-SY5Y cells treated first with Fe2+ to induce apoptosis, and then with vehicle (DMSO), free dauricine (DRC, 1 μM), blank micelles (PM, 5 μM) or dauricine-loaded micelles (DPM, 1 μM). Negative control group was treated with cell culture medium only without Fe2+, Cells were stained with annexin V-FITC and propidium iodide, then sorted by flow cytometry. b Percentage of apoptotic cells in different treatment groups. *P<0.05 (n=5)Back to article page
