Figures 3a and b show two dimensional images of PLGA scaffolding unseeded and seeded, respectively. The scaffolds were seeded with human embryonic kidney cells (HEK-293). It can be seen that in two dimensions little detail is noted in the image and it is difficult, if not impossible, to assess both porosity and the degree of cell growth.
