Primary mouse lung fibroblasts interact with 1 mg/ml HAp/Ch-PLGA (A–D and I–L) and A-HAp/Ch-PLGA particles (E–H) with no cytotoxicity or repulsion. A–D) Primary mouse lung fibroblasts surround HAp/Ch-PLGA particles. E–H) Primary mouse lung fibroblasts surround androstane-loaded HAp/Ch-PLGA particles. I–L) Primary mouse lung fibroblasts endocytose HAp/Ch-PLGA particles. Rhodamine-phalloidin-stained f-actin (red), DAPI-stained nucleus (blue), and auto-fluorescing HAp/Ch-PLGA and A-HAp/Ch-PLGA particles (green).
