Fig. 3From: Comparative analysis of titanium coating on cobalt-chrome alloy in vitro and in vivo direct metal fabrication vs. plasma sprayingCell proliferation. ELISA of the surfaces of TPS and DMF coating. As to the proliferation rate of the osteoblasts, the DMF group showed a better result, superior to the plasma-sprayed group on 24, 48, 72, and 96 h of incubation (p < 0.001)Back to article page
