Statistical analysis confirmed that CX3CR1eGFP/+ cell density, being of microglial origin, is significantly higher than CCR2RFP/+ cell density, being of macrophage origin, in all three experimental groups at day 14 after stroke (stroke-only group p = 0.013, MSC-treated group p = 0.038, IL13-MSC-treated group p = 0.017) (Fig. 4d). Here, IL13 is linked to stroke disorder.
