Primo Vascular System in the Subarachnoid Space of a Mouse Brain

Figure 5

(a) Stereo microscopic image of a dura mater with two PNs indicated with solid and dotted circles, which were 3,600 μm and 5,400 μm from the λ point (arrow), respectively. (b) Polarization microscopic images at a 45-degree rotation. The image in (c) has bright polarization signals along the transverse sinus, as seen in Figure 1(d). (d)–(g) Phase-contrast, DAPI-stained, MVX-10, and phalloidin-stained PN images, respectively, of the PN in the dotted circle. Its shape was oval and its size was 230 μm × 460 μm.
