On the 18th day of the gestation, variations in nuclearcytoplasmic ratio, size of R.E.R., mitochondria, lysosomes and microbodies were observed, with variations according to the localisation of hepatocyte inside the lobule. We report the most obvious effects as follows: An increase of R.E.R. in the central and perilobular zones. Mitochondria are larger and the rounded forms are more numerous inside the two lobular zones. The number of lysosomes and microbodies are only elevated in the perilobular cells. In conclusion, it is suggested that the hepatocyte organelles are significantly increased during gestation. This is probably due to the metabolic activation. These cellular modifications are only one aspect of the liver increase.</p>","PeriodicalId":75532,"journal":{"name":"Archives d'anatomie microscopique et de morphologie experimentale","volume":"74 4","pages":"229-36"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14959412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas the three cortical zones each had a specific histological structure, the ultrastructure of their cells showed a certain qualitative homogeneity. The differences corresponded essentially to the relative abundance of the constituents which are generally considered typical of steroidogeneous cells: mitochondria with vesicular cristae, smooth endoplasmic reticulum and lipid droplets. Their importance increased progressively from the zona glomerulosa to the zona reticularis. In this zone, the presence of gap and septate-like cell junctions, and mitochondria with vesicular cristae in close proximity to a smooth endoplasmic reticulum with numerous dilated tubules, suggested that steroidogenesis may be the most active. Ultrastructural findings were indicative of only quantitative differences between the steroidogenic capacities of the three zones of the mare adrenal cortex.</p>","PeriodicalId":75532,"journal":{"name":"Archives d'anatomie microscopique et de morphologie experimentale","volume":"74 3","pages":"193-203"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14951261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
