Identification of Primo-Vascular System in Abdominal Subcutaneous Tissue Layer of Rats

Figure 7

The inner space structure containing cells along the inside of the subcutaneous threadlike structure. (a) Continuous inner space (arrows) along the longitudinal axis of a threadlike structure revealed by Hemacolor staining. (b) Distribution of the cells (large granular cells, arrowheads; granules, dotted circle) in the inner space (marked as “b” in (a), 20–30 μm) of the vessel. (c) Large inner space structure (> 50 μm) inside the subcutaneous threadlike structure showing low cellularity revealed by Hemacolor staining. (d) Distribution of the cells (small round cells, arrowheads) in the inner space (marked as “d” in (c)) of the vessel. (e) Cross-sectional image (200 μm) showing an inner space (dotted square, > 50 μm) of a threadlike structure revealed by Hemacolor staining. (f) Inner space (marked as “f” in (e)) within a vessel slice containing granules (about 1 μm, inset). Note that the inner space contains the resident cells of the threadlike structure.
