Extended Data Fig. 1: Histological measurements post-infusion show no significant differences in infarct size or fibrosis between iECM and saline infused rats.

Infarct area at 5 weeks (a,b) and 3 days (c,d) post-infusion, reported as area (a,c) and percentage of the LV (b,d). Infarct fibrosis reported as area (e) and percentage of infarct area (f). g, Interstitial fibrosis of the remote myocardium reported as a percentage of area. N = 5 for saline and n = 6 for iECM for day 3 measurements, and n = 10 for both groups for 5 week measurements. Data are mean ± SEM. Add data are biological replicates.
