Figure 2

Nestin+ and Ki67+ cells are present in leptomeninges. (A) Immunostaining of nestin (red, left column) and nestin (red)/Ki67 (green, right column) at different stages of development; from top to bottom: E20, P0, P15, adult. Confocal microscopy analysis revealed that nestin+ cells (red) are present in the leptomeninges from embryonic stage E20 up to adulthood. Nuclei are stained with TO-PRO3 (blue). Scale bar: 50 μm. (B,C) Immunoperoxidase staining (brown) with anti-nestin antibody of brain sections. (B) Coronal section; the white dashed line highlights the border between neural parenchyma and meninges. (C) En face view showing nestin+ cells as an intricate net covering the brain. (D) Quantification of nestin+ cells normalized for the total number of nuclei in meninges. (E) Percentage of nestin+/Ki67+ cells; the values are normalized for the number of nestin+ cells. In (D,E), values are mean ± SD.
