Cardiomyocyte maturation assay
Functional iPSC induced cardiomyocyte fibers
4DCELL DEVICE
READ-OUTS
Beating frequency, observation of sarcomeres
STANDARD CULTURE LIMITATION
In standard cultures, cardiomyocytes derived from pluripotent stem cells have random shapes, are not organized thus showing immature properties.
CARDIOMYOCYTE MATURATION ASSAY
When cultured in a substrate with line adhesive cues, cardiomyocytes acquire elongated shapes, which regulates cell contractility and establishes and maintains myofibril alignment and an improved and regular cell beating.
EXAMPLE
Organization of cardiomyocytes in line patterns [1], and effect of myofibril alignment in contractility forces.
