MCRI Small Animal Physiology Core Lab

The MCRI Mouse Physiology Core Laboratory is dedicated to the application of whole-animal models to pursue questions related to the pathophysiology of cardiovascular disease. The MCRI has established a series of cardiovascular models in rodents that are in active use in both the MCRI and in laboratories around the U.S. and the world. Models developed at the MCRI include a mouse model of carotid injury; chronic myocardial infarction, transverse aortic constriction and others. Phenotyping methods developed at the MCRI Mouse Core include a closed chest electrophysiology catheter-based procedure and dual ventricular pressure volume loop recording among others. The Mouse Core also routinely performs standard disease models and phenotyping assays relevant to cardiac and vascular physiology, including models of ventricular pressure overload, left and right ventricular pressure-volume loop analysis, cardiac echocardiography, telemetry implantation for blood pressure and ECG monitoring and many others.

The facility is comprised of four separate rooms. The first and largest room is equipped with four independent and fully functional murine ‘operating stations’, each with a surgical stereomicroscope, tabletop gas anesthesia machine for rodent inhalation anesthesia, fiber optic lighting, temperature regulation with feedback control via rectal temperature monitoring, microsurgical instruments, heat pad and heat lamp, glass bead sterilizers, surgical supplies, shaver and weighing scales. In addition, there is a rodent respirator for use in open chest procedures and a Millar pressure volume hemodynamics area associated with one of these workstations. One of these four stations is primarily dedicated to closed chest survival electrophysiology studies.

The second room functions as the telemetry room. This temperature and humidity-controlled site includes the DSI equipment necessary to perform continuous ambulatory telemetric EKG and hemodynamic monitoring along with constant measurement of animal temperature and activity. The current room capacity allows for simultaneous measurement of two groups of eight mice.

A third room houses two Kent Coda mouse tail cuff blood pressure analysis systems with laptop computers and capabilities of noninvasively measuring 12 mice simultaneously.

The fourth room houses a VisualSonics ultrasound machine with an associated tabletop gas anesthesia machine, a heated platform with EKG and a micromanipulator for injections. This area contains two separate anesthesia platforms to enable echocardiography on either mice or rats. The room also houses a Dexa imager capable of measuring bone density and body composition of mice.

The facility also has access to a mouse exercise treadmill capable of exercising six mice simultaneously.

Leadership

The Mouse Physiology Core Lab is directed by Greg Martin, a full-time member of the MCRI and a highly experienced animal scientist with special expertise in animal physiology models. He serves on the Tufts University Institutional Animal Care and Use Committee.

Dr. Robert Blanton serves as the Scientific/Medical Director of the MCRI Mouse Physiology Core Lab, working closely with investigators and Mr. Martin on research plans, policies and procedures and ensures that all research in the core is carried out with the highest ethical standards for the use of animals. Dr. Blanton is an Associate Professor of Medicine at Tufts University School of Medicine, an Attending Cardiologist at Tufts Medical Center and the Assistant Director of the MCRI.
