Infection with E. coli-CR instead is represented in Figure 7B. In this case, it is interesting to note that, at 1 week, hA-MSCs are able to induce a significant decrease in the concentration of MBL compared to the same group, both at 24 h and at 72 h (p < 0.05), while there is no significance in AF without hA-MSCs. The gene discussed is MBL2; the disease is atrial fibrillation.
