Additional file 3: Figure S3. Immunostaining with cluster of differentiation receptors 45 (CD45) probing activated microglia and peripherical macrophage. at 5 months after mTBI in the hippocampus. (a–d) No changes in neurogenesis were observed at 5 months post injury or GW treatments by evaluating the % of area stained and morphology of the microglias. Qualitatively, there was a trend for an increased number of cells of with a doughnut-shaped blob (d, magnified inset), possibly as an infiltrating T cell as they were also observed within and along the blood vessels (d, arrows).
