This video describes an antegrade perfusion technique of an isolated mouse heart during which a perfusate is injected through the left ventricle, and eventually, it perfuses the entire myocardium. This method can be used to isolate cardiomyocytes from murine models and generate decellularized hearts for further downstream applications.

In this video, we perform Langendorff retrograde perfusion of an isolated mouse heart. During the procedure, the cardiac activity of the heart is maintained by perfusing it retrogradely with a perfusion solution via the coronary arteries using a cannula inserted into the ascending aorta. The model is used to study the cardiac pathophysiology of the heart.
FAQs
Flow rate, blood volume, and transit time describe different aspects of tissue perfusion. Flow rate indicates how quickly blood moves, blood volume reflects the amount present in the tissue or vascular region being assessed, and transit time captures how long blood takes to pass through it. Considering these parameters together helps connect circulation with delivery of oxygen and nutrients.
These approaches observe different measurable signatures of circulation. Flow sensors track blood movement, imaging methods follow signals associated with blood movement or tissue responses, and injected tracers provide a time-dependent way to follow passage through tissue. The selected approach determines which signal is collected and which perfusion parameters can be estimated.
Temporal measurements help distinguish blood movement from tissue responses and support estimates of transit time. Following a signal or response over time shows how circulation changes as blood passes through tissue, rather than providing only a static observation. This relationship allows researchers to characterize perfusion more fully and connect measurements with tissue oxygen and nutrient delivery.
A basic workflow begins by selecting a suitable way to track blood movement or tissue response, such as a flow sensor, imaging signal, or injected tracer. Researchers then collect measurements over time and use the resulting patterns to estimate flow rate, blood volume, or transit time. These values can subsequently be related to vascular function or organ performance.
Researchers can apply blood perfusion analysis to study normal physiology, investigate impaired circulation, and examine changes in vascular health. It also supports evaluation of experimental treatments by showing how circulation-related measurements change after an intervention. These applications make the method useful for linking blood delivery with tissue condition and organ performance.
Perfusion measurements provide a way to relate circulation to the supply of oxygen and nutrients that cells require. In biology, researchers can compare flow-related parameters with tissue metabolism, vascular function, or organ performance. This connection helps place blood-flow measurements within a broader physiological context and supports interpretation of how altered circulation may affect tissues.
