Gap Junction Remodeling in a Novel Engineered Heart Tissue System Cultured under Point Stimulation

Recent advances have shown the importance of electrical stimulation in enhancing maturation and differentiation of engineered heart tissues (EHTs). Conventional electrical maturation protocols pace their EHTs with field stimulation - the tissues are paced simultaneously in a uniform electrical field. This method has been shown to improve cellular alignment, increase contractility, and increase gap junction (Cx43) production. While Cx43...
