The recent advancements in tissue engineering and, more in general, in cell-based applications, has led to an ever increasing interest toward new materials for sustained cell proliferation and differentiation. Here, the preparation and the characterization of scaffolds based on poly(lactic-co-glycolic) acid / barium titanate nanoparticle composites are presented. In vitro testing on H9C2 cell line demonstrates how the presence of the nanoparticles positively affects both the proliferation and the differentiation of this muscle-like cell line. Finally, the possibility to obtain porous scaffold and, therefore, an actual 3D culture system, is introduced.
近年来,组织工程学领域取得了长足的进展,更广泛地说,细胞相关应用也受到了越来越多的关注,这促使人们对新型材料产生了持续促进细胞增殖和分化的兴趣。本研究中,我们制备并表征了基于聚(乳酸-共-乙醇酸)/ 钛酸钡纳米颗粒复合材料的支架。通过对 H9C2 细胞系进行体外测试,我们发现纳米颗粒的存在可以积极影响这种类肌肉细胞系的增殖和分化。最后,我们介绍了获得多孔支架的可能性,从而构建了实际的 3D 培养体系。
