Figure 3: Confocal laser scanning microscopic images of cross sections of a novel threadlike structure (NTS) within a rabbit lymphatic vessel. (a) The lymphatic vessel wall is stained red (DiI), and the rod-shaped nuclei (YOYO-1; green) are visible along the vessel wall. The dotted square is magnified in (b). (b) The long arrow indicates the nucleus in the outermost membrane, and the 2 short arrows and the asterisk indicate the NTS-associated outermost membrane and nucleus, respectively. Scale bars in (a) and (b) are 20 μm and 10 μm, respectively.
