摘要: Microcellular injection molding, a process capable of mass-producing complex plastic parts, and particle leaching methods were combined to fabricate porous thermoplastic polyurethane tissue engineering scaffolds. Water soluble polyvinyl alcohol (PVOH) sodium chloride (NaCl) used as porogens improve the porosity interconnectivity well hydrophilicity It was found in study that microcellular molding effective at producing high pore density porosity. The addition PVOH decreased diameter increased density. Furthermore, scaffolds with NaCl showed more interconnected pores. 3T3 fibroblast cell culture confirm biocompatibility Residual content after further improved adhesion proliferation. resulting offer an alternative scalable scaffold fabrication method for soft production.
