Correction: Development of a robust induced pluripotent stem cell atrial cardiomyocyte differentiation protocol to model atrial arrhythmia

• Correction of a concentration error in the preconditioning step of the atrial cardiomyocyte differentiation protocol, changing from 1 ng/mL to 2 ng/mL. • Ensures reproducibility and accuracy of the published protocol for generating atrial cardiomyocytes from induced pluripotent stem cells. • Important for researchers modeling atrial arrhythmias, as precise cytokine concentrations are critical for successful differentiation. • Highlights the importance of rigorous error correction in scientific literature to maintain research integrity.
