Summary
The fine structure of the different cells at the margin of the portal spaces was investigated in the foetal human liver. Two types of cells intermediate between biliary epithelial and parenchymal elements were described.
In addition, a type of cell in which both the cytoplasm and nucleus are electron-dense was observed. This element is different from the dark cell of Steiner et al. (1962b).
Résumé
Les auteurs, étudiant les diverses cellules épithéliales rencontrées dans la région périportale du foie foetal humain, décrivent deux types d'éléments qui possèdent des caractères ultrastructuraux intermédiaires entre ceux de la cellule épithéliale biliaire et ceux de l'hépatocyte.
Ils décrivent un type cellulaire à cytoplasme et noyau fortement denses, différents de ceux que l'on observe dans les «dark cells» de Steiner et coll. (1962b).
