Mmp14 was efficiently inactivated in BM-derived Mφs (BMDMs) and in cardiac Mφs sorted from 7-day-post-MI MAC-Mmp14 KO hearts; in contrast, Mmp14 expression did not differ between endothelial cells (ECs) purified from WT and MAC-Mmp14 KO 7-day-post-MI hearts (Figure 1—figure supplement 2D). Here, MMP14 is linked to myocardial infarction.
