Moreover, cTn-T, the marker of myocardial infarction, decreased significantly after treatment with exosomes isolated from pLVXcirc infected MSCs, reduced slightly after treatment with exosomes isolated from MSCs, whereas the cTn-T content did not significantly change after treatment with pLVXcirc when compared with the control (Figure 6B). The gene discussed is TNNT2; the disease is myocardial infarction.
