Extracellular matrix (ECM) plays a fundamental role in regulating cell attachment, proliferation, migration and differentiation. Both synthetic and biologically derived materials have been explored as an ECM in regenerative medicine and tissue engineering. To biomimick the extracellular matrix, we combined the advantages of the biological properties of nanofibrous scaffolds and the fusion protein to apply for the culture of human mesenchymal stem cells in vitro. In this study, we fabricated well random-oriented/aligned nanofibrous scaffolds with PCL, modified with hE-cadherin-Fc fusion protein and studied the synergistic effect of the scaffolds. The random-oriented/aligned architecture was observed in the nanofibrous scaffolds by SEM. XPS and WCA measurements evidenced that hE-cadherin-Fc was successfully modified on the PCL nanofibrous scaffolds and hydrophilicity of the scaffolds was well improved after fusion protein coating. The hE-cadherin-Fc modified markedly promoted the adhesion and proliferation of hMSCs and guided hMSCs to a spindlier morphology compared with unmodified nanofibrous scaffolds. Furthermore, hMSCs on the hE-cadherin-Fc-coated nanofibrous scaffolds also had differentiation potential. These results suggested that the combination of PCL nanofibrous scaffolds and hE-cadherin-Fc fusion protein may be a promising artificial ECM for the behavior of hMSCs in vitro.
