Özet
The aim of this study was to investigate the effects of heparin on the activity of osteoblast-like cells seeded on poly(caprolactone) (PCL) membranes. The membranes were prepared by solvent-casting technique in ∼150 μm thickness. Then they were treated with 1,6-hexanediamine solution and functionalized with covalently bound heparin. The morphology, proliferation, and differentiation of MC3T3-E1 preosteoblasts on these membranes were investigated in vitro. The heparin functionalized PCL membranes, compared to non-functionalized membranes, significantly stimulated osteoblast proliferation. The Scanning electron microscope images confirmed the stimulative effect of covalently bound heparin on the osteoblast-like cell proliferation. The alkaline phosphatase and osteocalcin levels for cells proliferated on heparin containing PCL membranes were higher than that of nonfunctionalized membranes. © 2011 The Author(s).
