Novel, low-cost bioreactor for in vitro electrical stimulation of cardiac cells by Joseph P. Licata, Jonathan A. Gerstenhaber, Peter I. Lelkes

“…However, there are discrepancies in the literature as to best practices for promoting cardiac differentiation using ES.MethodsThis study presents a novel, 3D printed bioreactor that delivers in vitro ES to human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), promoting cell maturity and functional readiness for implantation. Finite element analysis and mathematical modeling were used to model the fluid dynamics and to characterize in detail the delivery of pulsatile electrical signals, providing precise control over stimulation parameters such as voltage, current, and charge.ResultsThe bioreactor developed here provides an easy-to-use, inexpensive platform for culturing hiPSC-CMs under the influence of ES and low-shear fluid flow for enhanced nutrient availability, while its “drop-in” design facilitates real-time observation of cultured cells. …”
