Figure 1From: Cellular response to micropatterned growth promoting and inhibitory substratesMicrocontact printing guides neuronal morphogenesis (A) Shown on top is the silicon wafer with dimensions that are compatible with neuronal cell somata i.e., 10 μm wide lines separated by a pitch of 60 μm. Bottom half of panel shows an example of FITC-conjugated PLL lines printed onto coverglass. In all other cases unconjugated PLL was used. (B) Primary hippocampal neurons plated on micropatterned PLL and immunostained for neuron-specific beta-III tubulin. (C) Primary cortical neurons plated on micropatterned PLL and stained for F-actin. (D) Wafers with octagonal patterns designed to support a single neuronal cell body at each node. (E, F) Primary hippocampal neurons plated on micropatterned PLL and immunostained for beta-III tubulin. These neurons position their cell bodies at the nodes and their neurites extend outward, guided by the patterned PLL.Back to article page
