我们报告了一种新的共面介电泳(DEP)为基础的细胞图案化系统,用于产生可转移的肝细胞结构,类似于肝小叶,在文化。纸增强凝胶基质的使用提供了足够的强度,使这些构建体能够转移到96孔板中进行长期功能研究,包括未来的药物开发研究。实验结果表明,肝细胞形成DEP场诱导的结构对应于一个阵列的小叶模拟模式。通过使用荧光细胞染色技术在3天的时间内观察肝活力,同时与2D图案化细胞和未图案化对照相比,由于细胞系(HepG 2/C3 A)的层图案化,肝特异性白蛋白分泌功能显示出显著增强。这种“构建和转移”的概念在未来也可以适用于以微量滴定格式逐层构建芯片上的器官。我们报告了一种新的共面介电泳(DEP)为基础的细胞图案化系统,用于产生可转移的肝细胞结构,类似于肝小叶,在文化。
We report upon a novel coplanar dielectrophoresis (DEP) based cell patterning system for generating transferrable hepatic cell constructs, resembling a liver-lobule, in culture. The use of paper reinforced gel substrates provided sufficient strength to enable these constructs to be transfered into 96-well plates for long term functional studies, including in the future, drug development studies. Experimental results showed that hepatic cells formed DEP field-induced structures corresponding to an array of lobule-mimetic patterns. Hepatic viability was observed over a period of 3 days by the use of a fluorescent cell staining technique, whilst the liver specific functionality of albumin secretion showed a significant enhancement due to the layer patterning of cell lines (HepG2/C3A), compared to 2D patterned cells and un-patterned control. This “build and transfer” concept could, in future, also be adapted for the layer-by-layer construction of organs-on-chip in microtitre formats. We report upon a novel coplanar dielectrophoresis (DEP) based cell patterning system for generating transferrable hepatic cell constructs, resembling a liver-lobule, in culture.
