The Cell and Molecular Imaging (CMI) platform makes the visualization of biological systems, from the molecular to the tissue level possible.
Cryo-EM enables the reconstruction of near-atomic structures of molecular machines, super-resolution microscopy makes it possible to produce images with light at the cellular nanoscale, and with expansion and light-sheet microscopy it is possible to reconstruct small organisms or even entire organs, such as kidneys, in detail. The platform is organized in two Units: Cryo-EM and the new IMT (Integrated Microscopy Technologies), each with clear goals for the next four years, states SciLifeLab in a press release.
With these programs, the CMI hopes to reach out to many new laboratories around Sweden, and possibly, the international arena.
The Cryo-EM Unit
The Cryo-EM Unit, with nodes in Stockholm and Umeå, is developing a national Cryo-EM network, including four new host universities (Uppsala, Lund, Gothenburg and Karolinska Institutet). Staff employed at the host sites, with financial support from SciLifeLab, will be trained by the Cryo-EM Unit and will work as local technical support for starting new projects, thus spreading the technique in Sweden and hopefully “infecting” many new research groups.
The extended IMT Unit
The extended IMT Unit (formally known as ALM), in addition to the super-resolution and light-sheet microscopy technologies already on-site, will be hosting two new cutting-edge techniques: FIB-SEM (focused ion beam-scanning electron microscopy) and CAT (correlative array tomography), located in Umeå and Gothenburg, respectively. Bridging electron and photon microscopy, FIB-SEM and CAT will allow the visualization of bigger cellular structures and even larger multicellular 3D volumes. This will illuminate further the network of interaction within and between cells.
