HTA-exosomes and TAA-exosomes are equally found in the vimentin and KLF-4 mRNA expression, their cell metabolism and proliferation, whereas TAA-exosomes interestingly show more disrupting features of diseased aortic tissue, collagen secretion, and regenerative potential (Figure 3), which correlates with previous findings of aortic cells found during aneurysm formation. Here, VIM is linked to aneurysm.
