Of note, we described that the reduction in interstitial fibulin-3 expression early post-MI is likely due to the dramatic drop in the total number of Efemp1 positive fibroblast cell populations present in the heart at these time-points, and only minorly due to the downregulation of Efemp1 expression in F-WntX cells which occurred at day-7 (no change in Efemp1 expression was seen at day-3). This evidence concerns the gene EFEMP1 and myocardial infarction.
