Decellularized native extracellular matrix sections obtained from normal or pathological hearts with advanced HF (dECM-NH and dECM-PH, respectively) were seeded with human CPCs isolated from IHD patients (Figure 1A,B) and cultured up to 7 days, with standard culture on fibronectin (FN)-coating as control. Here, FN1 is linked to myocardial ischemia.
