Dannelsen af et ordentligt sarkomnetværk er vigtig for modningen af iPSC-afledte kardiomyocytter. Vi præsenterer en super opløsning-baseret tilgang, der giver mulighed for kvantitativ evaluering af den strukturelle modning af stamceller afledte kardiomyocytter, for at forbedre kultur betingelser fremme hjerteudvikling.
