Stabilized Window for Intravital Imaging of the Murine Pancreas

Employing high-resolution intravital imaging and an improved method of pancreas stabilization, we aim to enhance comprehension of the physiological dynamics of pancreatic adenocarcinoma, pancreatitis, and the healthy pancreas. This approach makes it possible to address gaps in the pathophysiological understanding, potentially advancing treatment strategies for these high-risk conditions. Single-cell resolution intravital imaging has illuminated the physiology and mechanisms of disease progression in various tissues.

However, the pancreas presents unique challenges due to its deep placement, compliance, and susceptibility to motion artifacts, hindering effective access for observation for both benign and malignant conditions. Our SWIP technique enhances murine pancreas stabilization compared to prior abdominal imaging windows. The uniquely designed frame features etched lines for the use of micro-cartography, which enables consistent region relocalization across multiple imaging sessions.

This facilitates the measurement of subcellular dynamics over days, providing valuable insights. The SWIP protocol enables stable, high-resolution, single-cell intravital imaging of the murine pancreas in normal and diseased states. It's especially beneficial for prolonged 3D and 4D imaging, offering insights into cellular interactions and disease mechanisms.

Invaluable for unraveling pancreatic physiology and pathology, this technique visualizes single cells and their context in vivo.
