Fig. 7From: CD44 promotes angiogenesis in myocardial infarction through regulating plasma exosome uptake and further enhancing FGFR2 signaling transductionSchematic diagram of the proangiogenic mechanisms of CD44 in MI. CD44 mediates the activation of the proangiogenic FGFR2 signaling pathway in endothelial cells and regulates the CAV1-dependent uptake of plasma exosomes, of which the contents miR-125b-5p and miR-223-3p enhance the FGFR2 signaling pathway to promote angiogenesis post-MIBack to article page
