iPSC Differentiated Cardiomyocytes
Ready-to-use, beating human cardiomyocytes differentiated from normal iPSCs (ASE-9211) are now available for purchase. The high-purity (≥80%) cardiomyocytes beat 2-3 days after recovery and express high levels of cnTnT. They are perfect in vitro tools for electrophysiology and biochemical assays, preclinical cardiac safety assessment, drug development, toxicity screening, and genetic studies.
- High-purity (≥80%)
- Integration-Free Differentiation Protocol
- Derived from our well-characterized, NIST iPSC Control Line

Case Studies
Case Study 1:
Characterization of the Cardiomyocytes Provided in the ASE-9703 Kit
Figure 1. Immunostaining of ASE-9703 iPSC-derived cardiomyocytes for a cardiomyocyte biomarker.
Cryopreserved cardiomyocytes, differentiated from Applied StemCell’s control iPSC line, ASE-9211 were
recovered in cardiomyocyte culture media. The cells were stained with cardiomyocyte marker cTnT (red) on day
2 after recovery. Image at 20x magnification.
Case Study 2:
Applied StemCell, Inc. has extensive expertise with iPSC cardiomyocyte differentiation. Previously, one of ASC's projects resulted in the development of high purity (>90%), beating human iPSC-derived Cardiomyocytes (Video 1) they expressed typical markers of cardiomyocytes, e.g. TNNT/cTnT and α-Actinin (Figure 1) and were validated for functional viability by patch-clamp and Fluo-4TM Direct Calcium Assay (Video 2). ASC’s cardiomyocytes were used for electrophysiological and biochemical assays, for example, the effect of compounds on the heart rate can be assayed by impedance-based measurements (Figure 2).
Characterization of iPSC-differentiated Cardiomyocytes
Video 1: Beating iPSC-derived Cardiomyocytes
Figure 2. After replating in Cardiomyocyte Maintenance Medium on the Matrigel-coated plates for 2 days, more than 85% of the iPSC-derived cardiomyocytes express cTnT and α-Actinin (Figure A and B).
Video 2: Calcium Flux of iPSC-derived Cardiomyocytes
Figure 3. Beating rate of iPSC-derived cardiomyocytes measured with xCELLigence RTCA Cardio System (ACEA Biosciences and Roche Applied Science). Cells were treated with various dosages of Isoproterenol. (Left) Before Treatment (50 μM; 10 μM; 5 μM); (Right) 30 min after treatment (50 μM; 10 μM; 5 μM).
