Expansion microscopy for the analysis of centrioles and cilia.

ABSTRACT: Centrioles are vital cellular structures that organise centrosomes and cilia. Due to their subresolutional size, centriole ultrastructural features have been traditionally analysed by electron microscopy. Here we present an adaptation of magnified analysis of the proteome expansion microscopy method, to be used for a robust analysis of centriole number, duplication status, length, structural abnormalities and ciliation by conventional optical microscopes. The method allows the analysis of centriole's structural features from large populations of adherent and nonadherent cells and multiciliated cultures. We validate the method using EM and superresolution microscopy and show that it can be used as an affordable and reliable alternative to electron microscopy in the analysis of centrioles an
