Stem Cells Grown in Osteogenic Medium on PLGA, PLGA/HA, and Titanium Scaffolds for Surgical Applications
Figure 7
von Kossa staining of hASCs grown in osteogenic medium for 28 days in a culture monolayer. (a) Negative control, (b) positive sample; the secreted calcified extracellular matrix are shown as black nodules Mag. 20x. (c) X-ray microanalysis performed on trabecular titanium, (d) PLGA scaffolds, (e) PLGA/HA scaffolds seeded with hASCs in osteogenic medium for 28 days. Calcium and Phosphatum peaks were detected, inferring that hydroxyapatite was formed.
