Figure 9

Three-dimensional reconstruction showing spatial relationships of ascending vasa recta (AVR; red tubules) and ascending thin limbs (ATLs; green tubules) to collecting ducts (CDs; blue tubules) for the same CD cluster shown in Fig. 6. AVR and ATLs are distributed relatively uniformly outside of and within the CD cluster and panels (a)–(d) show that this relationship continues along the entire axial length of the CD cluster. Tubules in panels (a)–(d) have been rotated forwards approx. 20°. Axial positions of panels (a)–(d) are shown in panel (e) with lower case letters. Tubules are oriented in a corticopapillary direction, with the upper edge of the image near the base of the inner medulla. Scale bar, 500 μm.
