The MCCSAIF is separated into two independent facilities – immunodeficient facility and regular mice facility. Severely immunocompromised mice require very high barriers to prevent the spread of diseases that normally do not evoke clinical illness in immune-competent animals. Therefore, imaging equipment is not shared between regular mice and immunodeficient mice. 

  • Lago SII system (Lee T. Todd Jr building basement; room 060E) is dedicated to imaging only immunodeficient mice. 
  • Ami HTX system in a partnering facility (Light Microscopy Core, HKRB Room 084B) is used to image regular/transgenic mice

Immunodeficient mice facility

Lago SII imaging machineTo start using Lago SII imaging system please schedule initial training with Leif Magnuson. Optical imaging is a proven low-cost, high-throughput way to observe tumor growth and treatment effect in living animals. Non-invasive, bioluminescent imaging of tumor growth and metastasis allows longitudinal evaluation of tumor development before, during and after treatment, offering an excellent preclinical strategy to assess tumor response and recurrence.

The Lago SII is connected to the XGI-8 Anesthesia System that allows continuous administration of isoflurane gas for anesthetizing animals during imaging with build in active scavenging system.

Lago SII features:

  • Bioluminescent imaging of metastatic tumors (quantification in vivo and ex vivo)
  • Detection of fluorescent reagents administered to mice or fluorescent GFP/RFP tumors (signal quantification ex vivo)
  • 5 mice imaging across BLI, FLI
  • 10 mice imaging across BLI, FLI with available nose cone adapter
  • Aura Image Analysis Software is available for free upon request from Spectral Instruments Imaging (SII) 
  • Analysis of fluorescent reagents distribution in vivo and ex vivo. Recommended dye spectrum for in vivo and ex vivo analysis of fluorescent reagents is Alexa647 or NIR

Note: Markey Cancer Center is supporting use of optical imaging experiment and there is no charge to use the Lago SII. Please not that isoflurane is not provided. 

GFP-RFP Panoramic imaging systemGFP/RFP Panoramic Imaging System

The GFP/RFP Panoramic Imaging System is used for visualizing fluorescent proteins expressed in cancer cells. A major benefit of this imaging system is real-time ex vivo examination of fluorescent signal to determine distribution of metastatic tumors within body cavities (eg, peritoneal cavity lymph node metastasis) and high-resolution photography to demonstrate metastatic burden in organs or body cavities. The detection and demonstration of metastatic tumors is enhanced in metastatic tumors established with cells expressing eGFP or tdTomato RFP enriched with two-three flow-cytometry selection cycles. 

small imaging facility equipmentEach surgery station is set up with a dedicated isoflurane vaporizer, heated surgical beds, induction chambers, microflex breathers and a scavenger system. Please follow following procedures:

  1. Surgery stations are equipped with two scavenging systems – passive, part of an isoflurane vaporizer and active scavenging system.
  2. Check passive isoflurane vaporizer scavenger system filter weight. Each filter in use is labeled with initial filter weight. If weight exceeds initial filter weight by +50 g discard the filter and replace with a new filter. Measure a new filter weight and write initial weight on a filter. 
  3. Turn on water pump to heat surgical beds. It takes approximately 30 min to heat surgical bed to 42°.
  4. Turn on active scavenger system and position scavenger system arms over induction chamber and microflex breather.
  5. Check isoflurane levels and refill if needed. Make sure that oxygen is off and there is no pressure in a vaporizer before refilling isoflurane.
  6. Turn on oxygen and adjust isoflurane flow.
  7. Discard syringes used for injection into provided container. Do NOT recap needles.
  8. Turn off vaporizer, keep the oxygen flow to remove excess of isoflurane though passive scavenging system.
  9. Turn off oxygen and scavenging system.
  10. Clean induction chamber and surgical station after each use with provided.

MRISC (Magnetic Resonance Imaging and Spectroscopy Center)

https://www.research.uky.edu/magnetic-resonance-imaging-and-spectroscopy-center

In vivo MRI and MicroCT are ideal for serial imaging animals to follow tumor progression. Furthermore, injectable agents can be used to enhance tumor contrast or interrogate metabolic activity. Please contact both David Powell, PhD at david.k.powell@uky.edu and Eric Forman at esform2@uky.edu if you would like to discuss using the MRISC.

Bruker Skyscan 1276A Skyscan MicroCT 1276 is available at the MRISC basement of the Whitney-Hendrickson building. Usage training and a calendar reservation system are available. 

The Bruker SkyScan 1276 is a fast, desktop in vivo micro-CT scanner for small laboratory animals (eg mice and rats) and biological samples. With micro-CT you can non-invasively scan any cross section through the body. Scan bone and tissue samples with high spatial resolution down to 2.8 µm pixel size. Generate realistic 3D images with a 16 Mp CMOS camera, and calculate internal morphology, including specific bone structural parameters.

7t biospec scanner7T BioSpec Scanner. The MRISC is equipped with a new 7T Bruker BioSpec, small animal, MRI scanner. This scanner is ideally suited for translational research with the capability to employ perfusion, diffusion tensor, anatomical, contrast, multinuclear spectroscopy, and functional techniques. We have experience imaging the heart, brain, spine, fat, lungs, vascular system, and cancer. 

The highest resolution achievable with the Bruker 1276 is 3 µm. In vivo imaging of mice is limited to around 8 µm. Real-time motion detection and respiratory and cardiac gating are available. Note that 3 µM resolution would require both a significant amount of time to fulfill the S/N requirements and would have to be performed on ex-vivo sample.

x-rad 225xl - research machineX-Rad225XL (Precision X-Ray Irradiation; PXi) is a system designed for small animal irradiation and large cell cultures. X-Rad225XL is located in the basement of Healthy Kentucky Research Building. The system is under an optional DIY policy; the researchers can irradiate cells and mice by themself. Please read the instructions below on how to proceed. 

Please note that the charge to use irradiation is $30/30min/day for cell culture XRT exposures (cell culture, worm, etc.) and $100/1h/day for animal exposure.

Access and training
