Dynamic and intricate monitoring of the excitation-contraction process of cardiomyocytes
The 5-year mortality rate for the over 23 million heart failure (HF) patients remains high, despite extensive efforts in development and investigation of therapeutic agents for the management HF. The physiological benefits of the treatments have often been coupled with unwanted side effects. Human induced pluripotent stem cell cardiomyocytes (hiPSC-CM) offer an exciting new model system to test both the efficacy and toxicity of new therapeutic approaches, including inotropic compounds which serve to modulate the force of cardiomyocyte contractility.
Assessment of Inotropic Compounds
Inotropic assays and other ex vivo whole organ assays are labor intensive, low throughput, and expensive. Alternatively, animal studies can also be conducted, but the actual predictivity of these assays and their translational potential to humans needs to be taken into account. Human iPSC-CM can provide a relevant model system for assessment of inotropic compounds. However, because of the relative immaturity of hiPSC-CM, assessment of inotropic compounds remain a challenge. ACEA Biosciences has developed an electrical pacing protocol which functionally matures hiPSC-CM (see maturity) enabling assessment of positive and negative inotropic compounds. Below is a summary table of inotropic compounds tested with electrically paced and functionally matured hiPSC-CM.
