Stem Cells Grown in Osteogenic Medium on PLGA, PLGA/HA, and Titanium Scaffolds for Surgical Applications
Figure 4
Scanning electron microscopic images of unseeded titanium scaffolds (a) and seeded titanium scaffolds (Ti6Al4V) with hASCs in osteogenic medium (b). Panel A shows the innovative multi-planar hexagonal structure of the scaffold imitating the structure of the trabecular bone, bar = 2 mm. In Panel B, cells appear to cover the surface of the trabecular scaffold uniformly and completely, bar = 100 μm; (c) Extracellular matrix between pores, bar = 20 μm.
