Light Microscopy/Digital Imaging
Light microscopy and digital imaging is integral to COHCCC’s research mission. The LMDI-SR provides a wide range of instruments that allow investigators to image numerous sample types in a variety of carriers such as slides, well plates, culture dishes, and live animals.
The LMDI-SR has 8 widefield microscope systems that have imaging capabilities in brightfield, fluorescence, differential interference contrast, phase contrast, and structured illumination (Apotome). The LMDI-SR has 5 systems that provide live-cell imaging services that include precise temperature control and CO2 delivery and a system that allows imaging under hypoxic conditions. The Zeiss confocal microscope systems (LSM700, LSM880, LSM900) are the most advanced available and are equipped with Airyscan super-resolution detectors that can increase the resolution and signal to noise ratio two-fold over confocal imaging. The LMDI-SR has two systems capable of 2-photon intra-vital imaging in live mice and rats. The Leica LMD7000 enables researchers to collect laser microdissected samples from slide mounted tissues, as well as live cells, which in turn can then be further analyzed via next generation sequencing, PCR, or mass spectrometry.
The LMDI-SR has added the Fluidigm Hyperion imaging mass cytometer to its services providing sophisticated multiparameter imaging data by ablating metal tagged antibodies from tissue samples. The LMDI-SR is directed by Dr Brian Armstrong who has extensive experience in light microscopic imaging and analysis and is supported by a highly trained staff (2 FTEs). The user base has access to the shared resource through iLab. In addition to extensive project-specific practical imaging training users also receive instruction in safety and the ethical collection of scientific imaging data. The LMDI-SR provides several professional software programs such as Image Pro Premier, AMIRA, Imaris, Autoquant, and Visiopharm that can be used to analyze and quantify imaging data, and the staff are well versed in the proper methods for handling large and complicated imaging data sets.

The objective of the Light Microscopy/Digital Imaging Core is to provide leading-edge microscopy systems and expertise to City of Hope investigators needing high-quality light microscope images and data. Microscopy and imaging are rapidly evolving fields that depend increasingly on expensive equipment and skills beyond the means of most individual laboratories. We seek to provide a range of research-grade light and confocal microscope platforms for simple observations and documentation suitable for publications or grant proposals. The core also makes available the latest research platforms for automated microscopy experiments, advanced observation techniques, and sophisticated digital image processing and analysis.
