Protocol for studying the superior mesenteric artery in mice using non-invasive micro-ultrasound imaging and anatomic dissection.

Abstract

The superior mesenteric artery (SMA), originating from the abdominal aorta, provides blood supply for the spleen, pancreas, intestine, and part of the colon. Here, we present a protocol for studying the SMA in the same mouse by combining non-invasive micro-ultrasound imaging and SMA dissection. We then detail procedures for tissue preparation, sectioning, and histological analysis. By allowing accurate identification of the SMA by ultrasound and anatomical dissection, this protocol can provide insights into SMA-related diseases in animal models.
