I am studying neurodevelopment using primary cerebellar granule neurons (CGNs) with a focus on studying morphology. CGNs undergo dynamic morphological changes in vivo and in organotypic slice cultures in vitro but I have not found papers studying morphology in primary cell culture.
What cell coating would you recommend for studying morphology in neurons in general? I've read PEI is good for having neurons remain spread out and unbunched, and I've also seen some protocols using fibronectin. My protocol recommends coating with poly-D-lysine and laminin for promoting neurite outgrowth but if there are other coatings that people recommend I would appreciate having some alternatives as I'm fine tuning my cultures.
