Overview

The Imaging and Cell Structure Core of the Liver Research Center operates in conjunction with the Analytical Imaging Facility (AIF) to provide a state-of-the-art resource for modern fluorescence and electron microscopy for Liver Research Center (LRC) Investigators.

The Core facilitates use of imaging techniques in liver research by supporting and assisting with use of specialized instrumentation, including laser scanning confocal microscopy, deconvolution microscopy, multi-photon microscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), cryo-electron microscopy (cryo-EM) and correlative light and electron microscopy (CLEM). In addition, the Core provides expertise in and assistance with specialized imaging techniques such as vesicle tracking, volumetric measurements, ultrastructural sample preparation, super resolution fluorescence microscopy (STORM/SIM), single-molecule Fluorescence in situ Hybridization (smFISH), Fluorescence Recovery After Photobleaching (FRAP), Fluorescence Resonance Energy Transfer (FRET) and Total Internal Reflection Microscopy (TIRF).

The Core provides technical support for assisted or independent use of the imaging technology and helps in the design of experiments, data acquisition and analysis related with relevant studies on hepatocytes and liver tissue.

An extensive selection of fluorescent protein vectors, fluorescent antibodies and probes, cell dye labeling technologies, and advice in the design of light and electron microscopy experiments is available.

Histopathology needs of LRC members are served by the Histology and Comparative Pathology Facility for animal tissues; and, a consulting group of pathologists led by Dr. Kathryn Tanaka at Montefiore Hospital for human tissue samples.
