“…Instead, they further explored the diversity of iPSC‐CM physiology using heterogeneous model populations. Population‐based modelling has been fruitful in understanding biological variabilities, and recently enabled a cross cell‐type platform that uses iPSC‐CM behaviours to predict human adult myocyte responses (Gong & Sobie, ). Kernik et al .’s model is the first study, to our knowledge, that integrates computational model populations into model development – a decision well‐suited for iPSC‐CMs, for which variability is a fundamental characteristic.…”
