Abstract

This work identifies and describes different material-scaffold geometry combinations for cartilage tissue engineering (CTE). Previously reported potentially interesting scaffold geometries were tuned and printed using bioresorbable polycaprolactone and poly(lactide-b-ethylene) block copolymer. Medical grades of both polymers were 3D printed with fused filament fabrication technology within an ISO 7 classified cleanroom. Resulting scaffolds were then optically, mechanically and biologically tested. Results indicated that a few material-scaffold geometry combinations present potential for excellent cell viability as well as for an enhance of the chondrogenic properties of the cells, hence suggesting their suitability for CTE applications.

3D打印关节软骨组织工程生物可吸收支架:纯聚己内酯(PCL)与聚乳酸-b-乙二醇(PLA-PEG)嵌段共聚物的比较研究

这项工作确定并描述了软骨组织工程(CTE)的不同材料-支架几何组合。先前报道的可能有趣的支架几何形状是使用生物可吸收的聚己内酯和聚(丙交酯-乙乙烯)嵌段共聚物进行调整和打印的。这两种聚合物的医用级都是在ISO 7级洁净室中使用熔丝制造技术进行3D打印的。然后对得到的支架进行光学、机械和生物学测试。结果表明，一些材料-支架的几何组合具有优异的细胞活力和增强细胞软骨性质的潜力，因此表明它们适用于CTE应用。
