    Area of Science:

    • Hepatology
    • Lymphatic System Research
    • Comparative Anatomy

    Background:

    • The precise location of hepatic lymph formation has been debated.
    • Mall's periportal space is a poorly understood anatomical region within the liver.
    • Existing knowledge on liver fluid dynamics and lymphatic drainage is incomplete.

    Purpose of the Study:

    • To investigate the anatomical and ultrastructural characteristics of the periportal space.
    • To determine the role of the periportal space in the formation of hepatic lymph.
    • To clarify the relationship between the perisinusoidal (Disse) space and the periportal space.

    Main Methods:

    • Light and electron microscopy were used to examine liver tissue.
    • Tissue samples were obtained from normal dogs, cats, and rats.

    Related Experiment Videos

  • Comparative analysis included cats with ligated hepatic lymph vessels.
  • Main Results:

    • Mall's periportal space was identified as a submicroscopic interstitial gap.
    • This space is situated between hepatocytes of the limiting plate and the portal canal's connective tissue.
    • The study elucidated the interplay between the perisinusoidal space and the periportal gap.

    Conclusions:

    • The periportal space is a key site for hepatic lymph initiation.
    • The findings refine our understanding of liver lymphatic anatomy.
    • This research provides a basis for further studies on liver fluid balance.
