Figure 5.

Sinusoids of Ah −/− mice are more anastomotic than those of Ah +/+ mice. Still images from 80× water immersion objectives were collected from videotapes of intravital microscopy of Ah +/+ (A) and Ah −/− (B) livers. Sinusoids are identified with dotted lines, as they not as readily visible in individual frames as compared with videotapes. A comparison of the internal diameter of individual sinusoids (ID), the number of flow-containing sinusoids (FCS), and the number of sinusoidal junctions per field (SJF) is shown (C–E, respectively) as mean and standard error. For ID and FCS, 28 and 18 fields were examined from four Ahr +/+ and three Ahr −/− livers, respectively. For SJF, 20 and 15 fields from three Ahr +/+ and three Ahr −/− livers were examined, respectively.
