Mouse Surgery Transplantation and Physiology Core
MR4 Room 2040
The Mouse Surgery Core provides the following low-cost surgical, transplantation, and physiology services to University of Virginia investigators only:
Currently Available Services:
- Hemodynamic Studies
This service is to measure blood pressure in the common carotid artery, in the chamber of left ventricle and/or right ventricle of mouse, through a Millar Catheter.
- Mouse and Rat Carotid Artery Injury
Common carotid artery will be injured by a spring wire (mouse) or a balloon catheter (rat). It is most common animal model to study the mechanisms of restenosis.
- Mouse and Rat Carotid Artery Ligation
The Left Common carotid artery will be ligated proximal to the superficial and internal carotid artery bifurcation in this model of vascular injury.
- Transverse Aortic Constriction (Aortic banding)
The transverse aorta will be constricted by tying a 7-0 silk suture around the vessel over a blunted 28-gauge needle. The needle will be removed, which restore the lumen to the size of the 28-gauge needle, and create acute left ventricle pressure overload. This model can be used for the study of cardiac.
- Abdominal A-V Shunt
(model of volume-overload induced heart failure) - The descending aorta isolated and clamped below the renal arteries and above the iliac aortic bifurcation. The aorta is punctured through the adjacent wall and into the inferior vena cava with a 26-gauge needle. The needle is removed fully, and the initial aortic entry puncture point closed with 11-0 suture. The clamps are removed after 10-20 s to insure proper drying, and the patency of the shunt verified visually by mixing of arterial and venous blood. This method of induction of volume-overload cardiac hypertrophy has been shown to produce an "eccentric" form of cardiac hypertrophy that is characterized by normal wall thickness, a disproportionately large increase in heart chamber volume.
- Mouse Femoral Artery Injury
Femoral artery will be injured by a spring wire through a cut on epigastric branch. This model can be done bilaterally and results in substantial intimal hyperplasia in mice without apoE or LDLR knockout.
- Aortic Pinning
Mouse aorta will be dissected out from the aortic arch to iliac artery (5 mm from bifurcation), cut open longitudinally, and pinned flat on silicone-coated dishes. Currently staining and imaging will need to be done by requestor.
Due to current constraints/resources, we are not fully able to provide the below services but if you are interested in the Core offering these in the future, please contact Bobi Thornhill at
BAT6D@virginia.edu to discuss. Based on number of requests priority will be determined along with available funding. Also, if you have other surgical needs not listed, please do not hesitate to ask and again we will prioritize as needed.
Future Planning:
- Mouse Heart Transplant
The heart of donor will be transplanted heterotopically into the abdomen of recipient. It is a very useful animal model for immune rejection studies.
- Mouse Aorta Transplant
The thoracic aorta of donor will be transplanted heterotopically into the abdominal aorta of recipient. This model is useful for transplanted atherosclerosis, chronic rejection and atherosclerotic lesion regression studies.
- Mouse Model of Vein Graft Disease
Autologous vein (external jugular vein) or Inferior vena cava of donor will be grafted into the infrarenal abdominal aorta by end-to-end anastomosis. It is useful model to study the mechanisms of vein graft disease (intimal hyperplasia).
