Observation of the Primo Vessel Approaching the Axillary Lymph Node with the Fluorescent Dye, DiI

Figure 4

The primo vessel extracted from the lymph duct. (a) DAPI signal image of the primo vessel that was extracted from the lymph duct. Notice some rod-shaped nuclei (arrows), which were similar to those used for the characteristic identification of primo vessels in a previous work [12]. (b) Phalloidin signal image of the primo vessel. The f-actins were along, not transverse to, the vessel. The pattern of the f-actins was different from the patterns of lymphocytes, as was shown in previous work [12].
