奈米點陣列的尺寸對神經膠細胞調控神經細胞增生的影響

Abstract

Traditionally regarded as supporting cells, glia cells are structurally and functionally poised as ideal sensors and regulators of local microenvironments. Emerging evidence suggests that glia have key roles in regulating neuronal development. The differentiated type of neuroblastoma glioma hybrid cell line, NG108-15, has widely used in in vitro studies instead of primary-cultured neurons. We culture NG108-15 cells on different sizes of nanodot arrays to examine how glia cells sense nanoenvironment stimulis and regulate neuronal development. Here we show that different nanodot size arrays change the number of neuroblastoma cells on unit area of glioma cells. Our results show that glia can sense nanoenvironment stimulis and response in different regulation of neuronal development. By examining gene expression, nanodot sizes also influence glia-mediated neuronal factor, such as Wnt3 and BDNF. Our results show that glia can sense nanoenvironment stimulis and response in different regulation of neuronal development. The nanodot arrays can serve as an appropriate tool for investigating glia-neuron interactions.
