The EM & ultrastructural pathology group provides three-dimensional EM analysis for the MRC Toxicology Unit programs and the external collaborative projects. Our “Nano-toxicology” is able to study a whole range of tissues and cells from the signalling receptor-complexes to the mouse brain involved in the response to toxins. Correlational changes between structure and function can be examined in nanoscale by using Cryo-TEM, SBF-SEM, and CLEM techniques for an in-depth visualisation of areas affected by toxins or drugs for mesothelioma in immune-oncology and neurogenerative diseases as well. We moved to Cambridge Old Addenbrooke's Site in November 2020. Thanks to the University and the SDC Builders, the brand-new EM suite has been developed with bright sunshine through the trees.


The designed EM techniques at MRC-TU:

  1. Array tomography (Imaging ordered arrays of ultrathin resin-embedded serial sections) for intracellular organelles
  2. Correlation Light and transmission or scanning Electron Microscopy (CLEM)
  3. Cryo-Electron Microscopy of Vitreous Sections (CEMOVIS)
  4. Deep-etch, or freeze-fracture EM for plasma membrane (membrane skeletons, clathrin-coats, caveolae), other membrane compartments, and cytoskeletal organizations [under construction]
  5. High-pressure freezing and freeze-substitution
  6. Image processing with machine learning modules
  7. Immune-gold labelling for protein subcellular localization
  8. Negative staining for pre-screening the sample quality on single particle analysis
  9. Serial-Block Face (SBF)-SEM for large-volume tissue and cellular architectures
  10. Single Particle Analysis (SPA) for purified protein-complexes
  11. TEM tomography for intracellular organelles
