The treatment with NaOH facilitated the intercellular separation of the specimen and completely removed reticular fibers around the sinusoid. In this way, the entire shapes of the Ito cells located in the perisinusoidal spaces or between the hepatocytes, were exposed under the SEM. The Ito cells were disposed at regular intervals of 30-55 microns all over the hepatic lobule, and surrounded the whole sinusoid with their subendothelial processes. SEM revealed a pattern of branching for the primary processes into secondary and tertiary processes. Furthermore, previously unknown thorn-like processes of the fourth order were also demonstrated. The Ito cells showed sparse microvilli on their surfaces confronting the hepatocytes, and occasional round elevations, these probably corresponding to lipid droplets. SEM also exhibited the relationship between the Ito cells and other types of cells in the liver. The Kupffer cells often interposed between the sinusoidal wall and the subendothelial processes of the Ito cells.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"49 3","pages":"349-57"},"PeriodicalIF":0.0,"publicationDate":"1986-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.49.349","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14918369","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}

Such lymphocytes were mainly of the small type with few cell organelles in a scanty cytoplasm, though a few were of the medium type with a moderate amount of cell organelles in an enriched cytoplasm. Macrophages in the non-myelinated white matter displayed a highly heterogeneous cytoplasm. In particular, \"cytoplasmic compartments\" in macrophages displayed specific structures differing from the inclusion bodies generally seen in phagocytic cells. The contents of such \"cytoplasmic compartments\" were rather similar to parts of the macrophage's own cytoplasm, though they were isolated from the cytoplasm by a membrane and gaps.

The hyperplastic proliferation of follicle epithelial cells, forming large round or oval cell clusters, occurred in 60-day-old mice. In 7-month-old animals, the ovaries were mostly occupied with invasive peritoneal epithelial tubules and masses of epitheloid cells which are apparently derived from the follicle epithelial cells. Although the ultrastructure of the oocyte and the follicle epithelial cell of the primary follicle is not different from that of +/+ control animals, the lack of gap junctions between the oocytes and the surrounding follicle epithelial cells may cause these abnormalities.

The N-terminal anti-glucagon serum reacted both to the A and the X cells, while the C-terminal anti-glucagon serum bound specifically to the X cells. These results suggested that the X cells contained pancreatic-type glucagon, whereas the A cells, an enteroglucagon (glicentin)-like substance. A fifth type of endocrine cell was scattered in the islets and contained serotonin-like immunoreactivity. Two kinds of peptide nerves were identified. Vasoactive intestinal polypeptide (VIP)-immunoreactive neuronal somata were located in the intrapancreatic ganglia. Nerve fibers and terminals containing VIP-like immunoreactivities occurred in the pericapillary space surrounding the islets.

Some villi reach their adult height in the neonate, while the rest gradually become longer during postnatal development. Epithelial cells lining the entire mucosal surface are undifferentiated and proliferative by day 15 of gestation. On day 16 of gestation, cells lose their proliferative capability at the upper part of the high villi, while cells lining the lower part of the villi and intervillous region remain undifferentiated as well as proliferative. As the crypt develops during postnatal development, undifferentiated proliferative cells are restricted in it, coming to reside in the lower two thirds of the crypt by day 28. The fine structural differentiation of absorptive cells starts at the upper part of villi on day 16 of gestation. The apical tubular system develops during the perinatal period. Large vacuoles, many lysosomes and lipid globules appear in suckling mice. The cells show the typical morphology of the absorptive cells by postnatal day 21.

Immature parietal cells were found in the lower part of the isthmus and throughout the neck. Cells at the same stage of maturation were often present side by side. Some cells in the neck, showing the characteristic morphology of immature parietal cells, also contained mucous granules resembling those in the mucous neck cells (intermediate cell). These findings suggest that: a chief cell may be formed by direct differentiation from the stem cell in the isthmus as well as by possible maturation of the mucous neck cell and mitotic division of the immature chief cell itself; and a parietal cell can be formed in the lower part of the isthmus and throughout the neck by direct differentiation from the stem cell or by mitotic division of the cell already determined to be a parietal cell as well as maturation of the intermediate cell.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"49 3","pages":"321-31"},"PeriodicalIF":0.0,"publicationDate":"1986-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.49.321","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14918367","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}

Two types of neural crest cells appeared in the somite-free environment. They could already be distinguished from each other shortly after beginning of migration. One type of the cells was distributed in the expanded space between the epidermis and the neural tube, with melanocytes differentiated from them. The other type of the cells migrated closely to the lateral wall of the neural tube. They aggregated as a cord on the ventrolateral side of the neural tube and gave rise either to neurons or to satellite cells of spinal ganglia. The sequence of cytological events along the development of the cells and the time required for each event were essentially identical with those of the melanocytes and spinal ganglion cells developing on the control side. The present results suggest not only that migration and differentiation of neural crest cells are independent of the possible regulation of the somites or their derivatives but also that the fate of neural crest cells is determined before the onset of migration.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"49 3","pages":"309-20"},"PeriodicalIF":0.0,"publicationDate":"1986-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.49.309","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14918366","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}
