Cell & Molecular Imaging Shared Resource

high resolution image of cancer cells

The overall goal of the Cell & Molecular Imaging (CMI) Shared Resource is to provide MUSC Hollings Cancer Center members with sophisticated equipment, technologies, training, and expertise required for successful, state-of-the-art cell and tissue-based microscopic imaging and image analysis. 

CMI carries out activities under three major themes:

  • Optical Microscopy Services: CMI maintains an array of contemporary equipment and expertise to facilitate high-end imaging of tissues and cells by Hollings members.
  • Innovative Techniques: CMI develops and applies new imaging techniques and applications to meet the emerging scientific needs of Hollings members.
  • Education and Training: CMI educates, trains, and consults on sophisticated imaging technologies that enable scientific discovery, including a biennial Charleston Workshop on Light Microscopy for the Biomedical Sciences, as well as a lecture series on cell and molecular imaging, especially as it relates to tumor biology.

Services

  • Access to state-of-the-art confocal and multiphoton microscopy, super-resolution microscopy, and second harmonic generation for imaging living cells in culture, live, and fixed tissues and for intravital imaging in live animals.
  • In-depth training in multiple imaging modalities including microscopic techniques, live cell imaging, multiphoton imaging, and pre-clinical intravital animal imaging.
  • Consultation and assistance concerning experimental design, sample preparation, probe selection, and data analysis for imaging applications.
  • Education in the fundamentals of imaging and image analysis technologies and their application, which are essential for appropriate utilization of these approaches.
  • Dissemination of information concerning the ongoing development of novel experimental strategies, emerging technologies, and data analysis techniques.

Applications

Fixed Cell & Tissue Imaging using chromogenic and fluorescence techniques in combination with antibody-based methods to monitor expression, distribution, and interaction of specific molecules.

Live Cell Imaging of parameter-sensitive fluorophores to monitor ions, electrical potentials, oxygen and nitrogen radical generation, NAD(P)H, mitochondrial and plasmalemmal membrane permeability, cell viability (apoptosis and necrosis), fluorescent protein biosensors, and other parameters.

Intravital Microscopy to monitor microcirculation, leukocyte margination, invadopodia, mitochondrial polarization, membrane permeability, radical generation, gene expression, detection of collagen fibers, and other factors in living animals and tissues.

Advanced Imaging Techniques: Fluorescence resonance energy transfer (FRET) and fluorescence recovery after photobleaching (FRAP) to characterize and quantify interactions between specific molecules and their mobility; second harmonic generation (SHG) microscope for label-free visualization of collagen; and Fast Airyscan super-resolution imaging with high quantum efficiency GaAsP photomultipliers.
