Author response image 1. (A) mRNA expression levels of genes related to senescence-associated secretory phenotype (SASP) by qPCR in FACS-sorted 7-day-post-MI cardiac Mφs (CD45⁺CD11b⁺F4/80⁺Ly6C^low cells) from WT and MAC-Mmp14 KO mice.

Data are means ± SEM of 4 mice per genotype. Unpaired t-test. (B) mRNA expression levels of genes related to SASP by qPCR in BMDMs from WT and MAC-Mmp14 KO mice. Data are means ± SEM of 4 mice per genotype. Unpaired t-test.
