Figure 4. Neuronal co-cultures on flat PLG disks.

Figure 4

Neurite extension on PLG disks with: surface immobilized pNGF/PEI complexes (a), surface immobilized pLUC/PEI complexes (b), and no DNA (c). TUJ1 (red) and Hoechst 33258 nuclear stain (blue) images shown are overlaid. Scale bars represent 100 μm. Quantification of neuron survival (d) and total neurite extension normalized to surface area (e) on pNGF-PLG disks and control disks. The symbol * indicates statistical significance, p < 0.001.
