Figure 3

Atomic force microscopy and fluorescence microscopy images of DPSCs on pSi and flat Si. Representative AFM deflection images of DPSC on pSi (A) and flat Si (B). Fluorescence microscopy images of DPSCs on pSi (C) and flat Si (D) with actin staining (red) and nuclei staining (blue), showing the filopodia formations. Scale bar = 20 μm. The arrows highlight the long thin filopodia growing from the main cell body, while the arrowheads show filopodia growing from lamellipodia.
