CD68 and Alzheimer disease: Figure 2 shows that both ySCs and oSCs treatment did not affect the number of Iba1+ microglia in the brain of old APPswe/PSENldE9 mice, whereas oSCs treatment increased cerebral CD68 expression in the AD mice compared with PBS control (One-Way ANOVA with LSD post-hoc test, F(2, 67) = 2.950; p = 0.020).
