Abstract

The retaining of biological activity of the immobilization bone morphogenetic proteins (BMP-2) was demonstrated in vitro and in vivo. The plasma spray coated titanium-alloy cylinders were also silanized with aminopropyltriethoxy silane (APS) and rhBMP-2 was adsorbed in an amount of ∼ 5μg/cm2. The biological activity of rhBMP-2 was measured by induction of alkaline phosphatase in MC3T3- E1 cells either employing p-nitrophenyl phosphate or ELF-97 as substrates. The results confirmed in vivo by employing a gap-healing model in the distal femur condylus of sheep.
