    Biomimetic camouflaged nanoparticles with selective cellular internalization and migration competences

    In the last few years, nanotechnology has revolutionized the potential treatment of different diseases. However, the use of nanoparticles for drug delivery might be limited by their immune clearance, poor biocompatibility and systemic immunotoxicity. Hypotheses for overcoming rejection from the body and increasing their biocompatibility include coating nanoparticles with cell membranes. Additionally, source cell-specific targeting has been reported when coating nanoparticles with tumor cells membranes. Here we show that coating mesoporous silica nanoparticles with membranes derived from preosteoblastic cells could be employed to develop potential treatments of certain bone diseases. These nanoparticles were selected because of their well-established drug delivery features. On the other hand MC3T3-E1 cells were selected because of their systemic migration capabilities towards bone defects. The coating process was here optimized ensuring their drug loading and delivery features. More importantly, our results demonstrated how camouflaged nanocarriers presented cellular selectivity and migration capability towards the preosteoblastic source cells, which might constitute the inspiration for future bone disease treatments.
