Electrophysiological integration and action potential properties of transplanted cardiomyocytes derived from induced pluripotent stem cells

Abstract

Transplanted iPSCM can persist in the long term and integrate electrically into host tissue, supporting their potential for cell replacement therapy. Quality of electrical integration improves between 6-12 days and 6-8 months after transplantation, and there are signs of an electrophysiological maturation. However, even after 6-8 months, AP properties of transplanted iPSCM differ from those of recipient cardiomyocytes.
