These included the basal surface of seminiferous epithelial cells, the basolateral processes of the Sertoli cell, junctions of the processes, and the basal or adluminal recesses. With the progressing stages of the spermatogonial cycle, three kinds of spermatogonia show different profiles and topographic relations. The basolateral processes of the Sertoli cells can be categorized into four types: conical, wedge-shaped, sheet-like and cup-shaped processes. The first two of the basolateral processes are joined together by close contact and/or overlapping junctions to form the floor of the basal recesses, and they encircle small-sized spermatogonia. The sheet-like processes mutually join by seam line junctions to form the ceiling of the basal recesses. During the spermatogonial cycle, the basal recesses first appear as separated lacunae, then form continuous labyrinth-like trenches, and finally make complicated honeycomb-like lacunae. The cup-shaped processes also are joined by close contact and/or overlapping junctions and are tightly attached by the primary spermatocytes with doughnut-like or linear bodies. The cordal arrangement and adluminal shift of the diverse spermatogonia will be discussed along with the cyclic transformations of Sertoli cell processes and their junctions.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 2","pages":"209-21"},"PeriodicalIF":0.0,"publicationDate":"1987-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.209","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14783533","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}

For comparison and evaluation of the effectiveness of this technique, experiments using grafts without the cryo-treatment were carried out. Cells in cryo-treated xenografts degraded into cell debris immediately after grafting and then were phagocytized by macrophages. After the cellular components had been removed from the graft, Schwann cell basal laminae remained intact in situ, serving as conduits for the regenerating axons. The process of nerve regeneration was almost the same as that observed in cryo-treated auto- and allografts, except that the regeneration was slightly delayed in the xenogeneic graft. In contrast, an extensive cell infiltration occurred in the non-treated grafts. It appeared that the donors Schwann cells in the graft deteriorated due to immunological reactions and were finally eliminated by macrophages, leaving their basal laminae undamaged in situ. The initiation of nerve regeneration including perineurial sheath formation in non-treated grafts was, therefore, significantly delayed, but once begun, it proceeded in the same manner as in the cryo-treated grafts. These findings strongly indicate that Schwann cell basal laminae can serve as effective pathways for regenerating axons even in the xenograft. Moreover, cryo-treated xenogeneic grafts are more desirable than non-treated ones, since dead Schwann cells in the former can be removed in the early period (4-14 days) from the graft without causing any immunological reaction, thus resulting in the facilitation of nerve regeneration.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 2","pages":"193-208"},"PeriodicalIF":0.0,"publicationDate":"1987-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.193","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14782892","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}

When porcine thyroid cells cultured in a monolayer on the type I collagen gel are overlaid with a second layer of collagen, changes occur in the polarity and arrangement of the cells. After 1 day of culture in the collagen sandwich, some cells in the monolayer proliferate, migrate and form two cell layers. The cell surfaces in contact with the upper or lower collagen gels always show basal characteristics. The primitive follicle lumen sealed by the zonula occludens first appears between two adjacent cells in a monolayer, or between the cells of the upper layer and those of the lower layer. Within 2 days of incubation, the cultured thyroid cells form rather flattened follicle-like cavities, even in the absence of TSH. Proliferation of the cells surrounding the lumen and luminal fusion would contribute to the development of such cavities. Bundles of numerous filaments are located along the apical and basal plasma membranes, and microtubules are markedly developed in the cytoplasm. The formation of the follicle-like cavities is inhibited by colchicine, suggesting the involvement of microtubules in the lumen-forming process. Immunohistochemistry shows that thyroid cells cultured in the collagen gel preserve the ability for thyroglobulin synthesis and basal lamina formation.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 1","pages":"113-27"},"PeriodicalIF":0.0,"publicationDate":"1987-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.113","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14740981","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}

Materials used were a gummy shark (Mustelus manazo), a cloudy dogfish (Scyliorhinus torazame) and a skate (Raja porosa). The vascular supply to the hypothalamo-hypophysial region of the elasmobranchs is carried out by the inferior hypothalamic arteries and their branches that originate from the internal carotid artery. In the gummy shark, a pair of inferior hypothalamic arteries send several branches to the median eminence running along the anterolateral sides of the distal adenohypophysis. These branches form the capillary plexus, displaying anastomosis and convolution at the ventral surface of the median eminence. The plexus assumes capillary glomeruli at the lateral region of the posterior median eminence. Numerous branches derived from the plexus are directed backward through the pars distalis, join with the capillary net work (which develop in the neuro-intermediate lobe) and are finally gathered together to form a thick hypophysial vein. The ventral lobe receives several arterial branches from the internal carotid arteries and carotid artery to form a unique vascular bed. Therefore, it is assumed that in elasmobranchs the hypothalamic control of the ventral lobe is weaker than that of adenohypophysial components.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"50 1","pages":"39-48"},"PeriodicalIF":0.0,"publicationDate":"1987-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.50.39","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14740979","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}
