Figure 6: Proportion of M1 and M2 macrophages in different groups. Note: (A) Proportion of M1 macrophages (ratio of CD11b+CD16/CD32+ cells to CD11b+ cells). (B) Proportion of M2 macrophages (ratio of CD206+ cells to CD11b+ cells). The OGD supernatant increased the proportion of M1 and reduced the proportion of M2 slightly. However, the hydrogen can reduced this impact to the normal level. *P < 0.05, vs. control group. OGD: Oxygen and glucose deprivation; H2: hydrogen.
