Actin assembly and disassembly is essential for any type of cell mobility. Variations in Actin content in liver tissue have been found to be an indicator for animal survival in a recent study utilizing a mouse model for systemic infection [1]. In vivo imaging of Actin, thus, provides access to enhanced understanding of cellular behavior in various areas of research including the response to infection and therapy. We use structured illumination and expansion microscopy to evaluate several approaches for in vivo Actin staining. [1] P. Martinac, A.T. Press, A. Medyukhina, K.-J. Benecke, J. Shi, D. Täuber, S.
