Key result
Novel Langendorff-injection technique yields up to ~90% viable cardiomyocytes across multiple heart chambers.
Why the study?
Established protocols for isolating single cardiomyocytes do not account for variation in connective tissue content between heart chambers, leading to low yield and difficulty isolating atrial cells.
No takes yet. Share an insight, caveat, or question.
May facilitate chamber-specific cardiomyocyte research; leaves open validation before routine lab adoption.
Butova et al. (2020) studied Cardiomyocyte isolation. Combined Langendorff-injection technique was evaluated on Yield of intact viable cells. The combined Langendorff-injection technique enables simultaneous isolation of high yields of viable cardiomyocytes from different heart chambers, achieving 60-90% for ventricular and 40-70% for atrial myocytes.
