Figure 5. This figure shows the phase contrast and fluorescent microscope images of Y79 cells grown on Poly(D,L-lactide-co-glycolide) (PLGA) scaffold microparticles. A: Phase contrast microscope picture of Gelatin-coated PLGA microparticles under 10× magnification. B: Phase-contrast images showing cells attached to the microparticles (white arrows pointing Y79 cells attached to microparticles) forming a three-dimensional growth over the microparticles under 10× magnification. C: Phase contrast microscopic image of 3-D growth of Y79 cells over scaffold microparticles (black arrow pointing to Y79 cells attaché to microparticles) under 40× magnification. D: Fluorescent microscopic image showing the 3-D growth of Y79 cells (labeled with Celltracker dye) over scaffold microparticle (white arrows pointing Y79 cells attached to microparticle) under 40× magnification.
