Standardized Method

Rationale: Primary cardiomyocytes are invaluable for understanding postnatal heart development and elucidating disease mechanisms in genetic and pharmacological models, however, a method to obtain freshly purified cardiomyocytes at any postnatal age, without using different age-dependent isolation procedures and cell culture, is lacking. Objective: To develop a standardized method that allows rapid isolation and purification of cardiomyocytes in high yield and viability from individual neonatal, infant, and adult mice. Methods and Results: Hearts of C57BL/6J mice were cannulated using a novel in situ aortic cannulation procedure optimized to allow cannulation of even the very small vessel of neonates (postnatal day 0-2, P0-2). Hearts were then subjected to Langendorff retrograde perfusion and enzymatic digestion. Cardiomyocytes were isolated after subsequent tissue disaggregation and filtration, in high yield (1.56-2.2x106 cardiomyocytes/heart) and viability (~70-100%). The larger size of infant (P10 and P13) and adult (P70), but not neonatal, cardiomyocytes relative to non-myocytes, allowed enrichment by differential centrifugation. Cardiomyocytes from all ages were further purified by immunomagnetic bead-based depletion of non-myocytes. Together, these procedures resulted in the isolation of highly purified cardiomyocytes (~94%) within 1 hour, enabling experiments using individual replicates. For example, RNA-sequencing of cardiomyocytes purified from one P2 male and female heart per litter (n=4 litters) showed distinct clustering by litters and sex differences for nine differentially expressed genes (FDR<0.005). In situ fixation via coronary perfusion, performed immediately after tissue digestion, preserved the cytoarchitecture of isolated cardiomyocytes (yielding ~94% rod-shaped cardiomyocytes at all ages), allowing capture of spindle-shaped neonatal cells undergoing mitosis, as well as enabling accurate quantitation of cardiomyocyte area and nucleation state. Conclusion: The procedures developed here provide a universal protocol for the rapid isolation and purification of high-quality cardiomyocytes from hearts of any postnatal age, even those of neonates, thereby enabling direct comparisons between individual hearts.
