Multi-modal cell imaging is the combination of two or more imaging techniques, and it plays a crucial role in advancing our understanding of cellular structures and functions. In the field of cellular biology research, imaging techniques provide invaluable insights into dynamic cellular processes, molecular composition, and overall cellular behavior. This blog post explores the emerging trends in multimodal cell imaging and the impact they have on the scientific community’s ability to uncover the complexities of cellular biology.
In recent years, several emerging trends have been identified in multi-modal imaging and have been used to enhance our understanding of cellular biology. Some of these trends include nano-based multi-modal imaging and correlated multi-modal imaging (CMI), as well as new tools such as spatial omics technologies. We can see a promising future for multi-modal cell imaging techniques as technology continues to advance, but for now, let’s take a look at what we already have access to.
Correlated Multi-modal Imaging
CMI is another trend that has gained attention in recent years. It involves obtaining information about the same specimen using two or more complementary imaging modalities.1 By combining the strengths of different modalities, such as fluorescence imaging and electron microscopy, researchers can gain a more in-depth understanding of a specimen’s structure and function. CMI enables researchers to correlate molecular information with cellular and tissue morphology, providing valuable insights into cellular processes and interactions.
Integration of Fluorescence and Electron Microscopy
Briefly mentioned above, fluorescence microscopy and electron microscopy are two powerful imaging techniques often used in cellular biology research that are being combined. Fluorescence microscopy utilizes fluorescent labeling to visualize specific cellular components or molecular interactions. On the other hand, electron microscopy produces high-resolution images of cellular structures. By combining these two techniques, researchers can take advantage of a wide range of benefits, resulting in a more in-depth understanding of cellular dynamics.
Super-resolution Multi-Modal Imaging
Super-resolution microscopy has revolutionized the field of Multi-Modal Imaging in biological research by enabling unprecedented visualization of cellular structures and molecular interactions at nanometer-scale resolution. By overcoming the diffraction limit of conventional light microscopy, super-resolution techniques such as stimulated emission depletion (STED) microscopy, structured illumination microscopy (SIM), and single-molecule localization microscopy (SMLM) provide intricate details of subcellular components. This breakthrough technology allows researchers to simultaneously examine multiple biological parameters, including protein localization, protein-protein interactions, and cell morphology, within the context of intact cellular systems. By combining super-resolution microscopy with complementary imaging modalities such as fluorescence, electron microscopy, and Raman spectroscopy, Multi-Modal Imaging approaches offer a powerful toolkit to unravel complex biological processes with exceptional precision and depth.
Spatial Omics Technologies
Spatial omics technologies are regarded as powerful tools in multi-modal cell imaging. These methods enable researchers to study cellular organizations and interactions within tissues at single-cell to subcellular resolution2. By identifying specific compartments or regions with a differential transcript or protein abundance, spatial omics technologies help define cellular phenotypes and uncover the intricate spatial relationships between cells within complex tissues.
