(A) Schematic of hydroxyapatite particles. (B) HA internalization by BMDCs. SEM images of BMDCs incubated with N5, R20 and S20 particles for 18 h. (C) Confocal fluorescence microscopy images of BMDCs incubated with FITC-labelled (green) S0.1, N5, R20 and S20 for 24 h to visualize the individual internalized particles. Membrane staining with phalloidin–TRITC (red) and nuclear staining with DAPI (blue).
