Analysis of Spliceosomal snRNA Localization in Human Hela Cells Using Microinjection

¹Laboratory of RNA Biology, Institute of Molecular Genetics of the Czech Academy of Sciences, ²Department of Genetics and Microbiology, Faculty of Science, Charles University

Biogenesis of spliceosomal snRNAs is a complex process involving various cellular compartments. Here, we employed microinjection of fluorescently labelled snRNAs in order to monitor their transport inside the cell.

¹Laboratory of Integrative Biology, Institute of Molecular Genetics of the Czech Academy of Sciences

Presented here is a protocol for the isolation of mouse hepatocytes from adult mouse livers using a modified collagenase perfusion technique. Also described is the long-term culture of hepatocytes in a 3D collagen sandwich setting as well as immunolabeling of the cytoskeletal components to study bile canalicular formation and its response to treatment.

We present a protocol to measure the elastic moduli of collagen-rich areas in normal and diseased liver using atomic force microscopy. The simultaneous use of polarization microscopy provides high spatial precision for localizing collagen-rich areas in the liver sections.
