Abstract
  • Several studies suggest that the surface coating of titanium could play an important role in bone tissue engineering. In the present study, we have followed a particular biomimetic strategy where ultrasonically or electromagnetically stimulated SAOS-2 human osteoblasts proliferated and built their extracellular matrix on a titanium plasma-spray surface. In comparison with control conditions, the ultrasonic stimulation (average power, 149 mW; frequency, 1.5 MHz) and the electromagnetic stimulation (magnetic field intensity, 2 mT; frequency, 75 Hz) caused higher cell proliferation, and increased surface coating with decorin, osteocalcin, osteopontin, and type I collagen together with higher incorporation of calcium and phosphorus inside the extracellular matrix. The immunofluorescence related to the preceding bone matrix proteins showed their colocalization in the cell-rich areas. The use of the two physical stimulations aimed at obtaining the coating of the rough titanium plasma-spray surface in terms of cell colonization and deposition of extracellular matrix. The superficially cultured biomaterial could be theoretically used, in clinical applications, as an implant for bone repair. (literal)
