摘要：

A novel, simple and efficient approach for designing a 3-D structure of poly(vinyl acetate) (PVAc) fibers layer coated on chemically treated Ti coupons by means of air jet spinning (AJS) approach has been developed. The effects of the PVAc AJS membrane mats on apatite formation were evaluated in vitro with immersion in simulated physiological Hank's balanced salt solution. The MC3T3-E1 pre-osteoblast cell-line has been utilized for measuring the bone cell response. The results suggest that the AJS produces a distinct porous layer of 3-D interconnected fibers on Ti with strong adhesion which offers a suitable surface structure for cell attachment. A significant amount of apatite-like formation and cell spread with strong local adhesion were identified on the PVAc fibers compared to the neat samples. Published by Elsevier B.V.
