In Vitro Bioactivity Study of RGD-Coated Titanium Alloy Prothesis for Revision Total Hip Arthroplasty

Figure 3

Osteoblasts spreading morphology in different groups after 24-hour incubation. Osteoblasts in the CTA group spread poorly (a), but osteoblasts in the FTA group exhibited normal spreading morphology (b–d). Red, cytoskeletal staining with rhodamine phalloidin; green, RGD-FITC coated on the surface of Ti6Al4V alloy (bar = 50 μm).
