Description
Abstract
Aim. As a specialized intraparenchymal
vascular conduit, hepatic sinusoids play a key role in
liver microcirculation. This study aimed to explore the
three-dimensional (3D) morphological changes of
cirrhotic sinusoids by serial histological sections.
Methods. Cirrhosis was induced by tail vein
injection of albumin in Wistar rats with a positive
antibody. A total of 356 serial histological sections were
prepared from liver tissue blocks of normal and cirrhotic
rats. The optical microscope images were registered and
reconstructed, and 3D reconstructions of the fine
structures of fibrous tissues and sinusoids were
subsequently visualized.
Results. The fibrosis area of the cirrhotic sample was
6-16 times that of the normal sample (P<0.001).
Cirrhosis led to obvious changes in the distribution and
morphology of sinusoids, which were mainly manifested
as dilation, increased quantity and disordered
distribution. Compared with normal liver, cirrhotic liver
has a significantly increased volume ratio, number and
volume of sinusoids (1.63-, 0.53-, and 1.75-fold,
respectively, P<0.001). Furthermore, the samples were
further divided into three zones according to the oxygen
supply, and there were significant differences in the
morphology of the sinusoids in the normal and cirrhotic
samples (P<0.05). In particular, morphological
parameters of the cirrhotic sinusoids near the portal area
were obviously greater than those in the normal liver
(P<0.05).
Conclusion. 3D morphological structures of hepatic
sinusoids were reconstructed, and the adaptive
microstructure changes of cirrhotic sinusoids were
accurately measured, which has an important
implications for the study of hepatic microcirculation
and pathological changes of cirrhosis.
