Table 6 Comparative hepatobiliary volumetric studies.

From: Non invasive in vivo investigation of hepatobiliary structure and function in STII medaka (Oryzias latipes): methodology and applications

Component (% Volume) Rat [78] Dog [79] Rainbow trout [80] Golden Ide [81] Brown trout [16] Medaka
Hepatocytes 77.8 84.4 84.5 88.9 87.3 91.5
Biliary Epithelia 22.2 15.6 15.5 11.1 15.18 -
Sinusoid Lumen 10.6 4.3 9.4 6.6 6.23 7.51
Bile Canaliculi 0.4 0.5 1.1 0.7 0.45 0.96
  1. Given are comparative metrics for components of the hepatobiliary system from mammalian and piscine studies. When comparing metrics note that values for medaka are from 3D in vivo investigations, metrics from other studies were derived from ex vivo histological and ultrastructural studies. No total volume was obtained for biliary epithelia in medaka, however, these cell types were found predominantly in the hilar region of the liver, and it is estimated they comprise a similar volume as those reported in other studies above.
