Microstructured Topography Enhanced the Responsiveness of Voltage-Gated Calcium Channels in H945RB. 3 Human Neural Progenitor Cells. In 2009 3rd International Conference on Bioinformatics and Biomedical Engineering (pp. 1-4). IEEE.https://ieeexplore.ieee.org/abstract/document/5163055/https://nru.uncst.go.ug/handle/123456789/10951A topographical substrate with a packed polystyrene microbead (1.98 plusmn 0.20 mum in diameter) array was fabricated for the development of cell-based assay systems targeting voltage-gated calcium channels (VGCCs). We found that the microbead arrayed substrates enhanced the attachment and spreading of the cultured human neural progenitor cells (H945RB.3) as compared to the flat polystyrene surfaces. Microbead arrayed substrates also facilitated the development of higher VGCC responsiveness upon neuronal differentiation than flat substrates. The enhancement of both VGCC responsiveness and cell spreading were most significant until day 14 into differentiation.enArticle
