Abstract

In this study, we looked at the adhesion of osteoblasts on 3D polycaprolactone (PCL) scaffolds compared to 2D PCL films and glass coverlsips. This adhesion was quantified after 24 hours by staining for vinculin, a marker of cell-substrate adhesion, and viewing the cells with confocal laser scanning microscopy (CLSM). Cells adhered on the glass and PCL films, with a larger number of cell spread area and number of focal adhesions on the glass compared to the PCL films (p<.05). Cells on the PCL scaffolds had a smaller cell spread area and lower number of focal adhesions compared to both glass and PCL films (p<.05). However, large clusters of cells were evident on the struts of the PCL scaffolds, indicating that cells did adhere, but that the mechanism of adhesion in 3D may differ from that in 2D.
