Compared to the ischemia control group (Figures 4(e)–4(h)), MSC infusion induced a slightly but significantly reduced number of GFAP+ astrocytes (from 36.4 ± 9.72/view field to 31.4 ± 4.54/view field) (Figures 4(i)–4(l)), but an increased number of GFAP+/IGF-1+ double-positive cells (from 21.7 ± 3.78/view field to 27.27 ± 3.43/view field) (Figures 4(i)–4(l), and 4(o)). Here, IGF1 is linked to ischemia.
