In vivo bioluminescent imaging (BLI). a Representative BLI images (7 days after surgery) of a mouse+MSCs (IM, left panel) and a mouse+MSCs and aliskiren (IMA, right panel). The signal due to MSCs engraftment localized over the heart region (red arrows), while the signal due to the osmotic pump material localized on the flank where the pump was installed (blue arrows and magnification). b As the BLI signal strongly correlates with the number of cells, the percentage of living cells has been plotted for both groups, considering the signal obtained at day 1 as a reference (100 % viability). Data represent mean±SEM. *p<0.05 vs. mice+MSCs
