为了改善药物开发过程中因肾毒性造成的磨损率,需要一种更好的肾脏体外模型。我们展示了一个肾脏近端小管的模型,在该模型中,一片近端小管上皮细胞被固定为隔膜,隔开两个液室,而不存在支撑膜。使用聚(N-异丙基丙烯酰胺)(PIPAAm)温度响应面制备细胞片,并使用3D打印机构建定制的生物反应器以产生合适的模具。用纤维连接蛋白功能化的表面种植细胞,将细胞片悬浮起来。还需要进一步的测试来确定生物反应器的生存能力。
To improve on attrition rates during drug development due to nephrotoxicity, a betterin vitromodel of the kidney is needed. We demonstrate a model of the kidney proximal tubule in which a sheet of proximal tubule epithelial cells is fixed as a membrane separating two fluid chambers without the presence of a supporting membrane. Cell sheets were prepared using a Poly(N-isopropylacrylamide) (PIPAAm) temperature responsive surface and a bespoke bioreactor was constructed using a 3D printer to produce an appropriate mould. Cell sheets were suspended using a fibronectin functionalized surface seeded with cells. Further testing is needed to determine viability in bioreactor.
