Small animal imaging facility is big boon to research
Date:8/30/2007

glow, says Dr. Hu. For example, after a heart attack, you can look and see if certain genes are up-regulated, such as inflammatory genes. Now we take the same animal model back to the MRI machine and track how many cells have moved to the site of injury. So, we can combine the information and say, okay, potentially those cells that have been mobilized are due to the gene expression. We can try and link cause and effect so it becomes more of a valuable image, says Dr. Hu. Right now he and Dr. Yanasak are fine-tuning how to make MRI and optical scanning work optimally together and how to also quantify gene expression.

The number of MCG scientists using the facility is significant and growing, says its director. Dr. Adviye Ergul, for example, is looking at blood flow in the brain of her diabetes model and Dr. William Hill is looking at stroke event and recovery.

We are very open to any interesting ideas that generate interesting scientific data or grant funding opportunities, says Dr. Hu. Goals include becoming an MCG core laboratory facility and adding a small animal PET scanner and ultrasound.
