RACC-incorporated GC nanoparticles induced time-dependent inhibition of MG-63 and Saos-2 cell proliferation. a and c, MTT tests on MG-63 and Saos-2 osteosarcoma cell line; b and d, trypan blue tests on MG-63 and Saos-2 osteosarcoma cell line. Cells were cultured in medium containing empty GC vesicles (□) or RACC-incorporated GC nanoparticles (●) with 20 μM RACC, added at a day “0,” for the time indicated. Results correspond to three different experiments and values are expressed as mean
