Evidence for the Primo Vascular System above the Epicardia of Rat Hearts

Figure 1

Illustration of the PVS above the epicardium of the rat heart with real stereoscopic images of the PVS stained with Cr-Hx. The illustration suggests the network system of the PVS; the two question marks remain to be studied. The real stereomicroscopic images in (a), (b), (c), and (d) show PNs (dotted circles) and PVs (arrows). The stereoscopic image in (e) is a magnified image of the area in the dotted rectangle of image (d). Tiny node-like structures are visualized in image (e). The scale bars of (a), (b), (c), (d), and (e) are 507 μm, 1106 μm, 207 μm, 430 μm, and 56 μm, respectively.
