Discovery of Endothelium and Mesenchymal Properties of Primo Vessels in the Mesentery
Figure 1
Primo vessels in the mesentery in fresh tissues and cryosections by phalloidin and DAPI staining. (a) The differences among primo vessels, vascular vessels, and lymphatic vessels. Primo vessels consist of phalloidin positive cells with characteristic rod-shaped nuclei, linear arrangements paralleling with the vessels. Vascular smooth muscle cells were also sensitive to phalloidin but showed thoroughly different appearances (yellow arrowheads). In lymphatic vessel, the endothelial cells formed the vessels in a network way (yellow arrows). (b) The differences among primo vessels, vascular vessels, and lymphatic vessels in cryosections. Phalloidin positive cells with rod-shaped nuclei; linear arrangements in longitudinal sections were primo vessels (yellow dashed area). Vascular vessels showed smooth muscular cells circulating the vessels and lymphatic vessels were formed in a network way.
