Scaffold-based lung tumor culture on porous PLGA microparticle substrates

Cellular viability on porous MPs.
(A) Live/dead and DAPI stained particles after 1-day culture indicating that the A549 lung cancer cells could attach onto the fibronectin-coated particles within 24 hours and were viable (green = live, red = dead, Scale = 10 μm). (B) SEM images of cell attachment on PLGA-Gelatin, PLGA-SBC and PLGA-PMPs demonstrate that the cells were clearly seen attached onto the surface of the MPs (arrows).
