Abstract
In this chapter we describe the use of correlative light-electron microscopy (CLEM) to study, in cultured cells, the turnover of damaged mitochondria by PINK1/Parkin-dependent mitophagy. CLEM combines the advantages of light microscopy, which allows to image and rapidly screen a large number of the cells, while electron microscopy provides high-resolution imaging of these selected cells and a detailed structural analysis of their cellular organelles. We describe in detail how to prepare the cell cultures for optimum preservation of their cellular ultrastructure for CLEM using the most suitable buffers, fixatives, and embedding resins. These protocols are applicable for detailed ultrastructural analysis in a wide variety of organisms and cells, ranging from prokaryotic bacteria to mammalian cells.
