Figure 6. Cell layer position influences spatial synapse distribution.
(A1 and B1) Schematic view of shifted cell layer position and NGF/B27 (12B27pNGF-53) gradient exposure. (A2 and B2) False color image shows cell pattern dependent synapse distribution in the micropatterned cell culture after 9 DIV. Pre-synaptic units: synaptophysin (red), cell nucleus: DAPI (blue), scale bar = 100 µm. (A3 and B3) Surface plots of synapse distribution with linear fit of data demonstrate synaptic gradient response, z = 5 µm.
