The power of microscopic diversity

There is no better way to find the answer to a problem than asking questions from different points of view or, in this case, from different microscopes: different concepts, different lenses, and clearly different results.

In the image above – from a study on the octopus Kölliker’s organs (KO) – we can observe three images taken with two different microscopy techniques.

The first technique is light sheet microscope, or Selective Plane Illumination Microscopy (SPIM), which allows to observe a complete sample without doing histological sections. This technique was applied at the Mesoscopic Imaging Facility of the European Molecular Biology Laboratory – Barcelona (EMBL Barcelona) to samples of an Octopus vulgaris or common octopus, to obtain the first two images.

The last image on the right shows the same octopus observed with a scanning electron microscope (SEM) in which the surface of the sample is scanned, but not its interior.

    Each technique offers a unique window into the microscopic realm. For example, electron microscopy delves into the ultrastructural level, revealing organelles and their internal landscapes, while live-cell imaging captures dynamic processes like cell division and protein trafficking.
