    Notes: Abstract. In the amphibian small intestine, the epithelial transformation from the larval to adult type is mainly the result of degeneration of the larval epithelium and development of the new (adult) epithelium. In this analysis at the cellular level, we chronologically examined apoptosis and cell proliferation in the Xenopus intestine by using in situ nick end-labeling of genomic DNA (TUNEL) and bromodeoxyuridine (BrdU) immunohistochemistry. During pre- and prometamorphosis, few apoptotic cells were detected by TUNEL, and a small number of proliferating cells randomly distributed in the larval epithelium were labeled by BrdU. At the beginning of the metamorphic climax, when primordia of the adult epithelium were first detected, numbers of apoptotic cells suddenly increased in the larval epithelium, whereas numbers of proliferating cells increased only in the adult epithelium. Subsequently, a dramatic cell loss of the larval epithelium and a rapid growth of the adult epithelium occurred. Following complete epithelial replacement, the adult epithelium became differentiated into a simple columnar epithelium possessing a cell renewal system similar to that of mammalian intestinal epithelium. These results indicate that larval epithelial apoptosis progresses simultaneously with active proliferation of the adult epithelium during the early period of metamorphic climax, which coincides with the modification of the basement membrane lining both types of epithelia.

    Notes: Summary Pieces of hairy skin tissue of fetal rat were transplanted into the anterior eye chamber of adult rats. The ability of autonomic and sensory nerve fibers from the host iris to innervate the grafted skin tissue was immunohistochemically and enzyme-histochemically examined using antisera against tyrosine hydroxylase (TH), substance P (SP), calcitonin gene-related peptide (CGRP) and vasoactive intestinal peptide (VIP), and a reaction medium for acetylcholinesterase (AchE). The grafted tissue was successfully implanted and connected with the host iris. Epidermis, dermis, subcutaneous tissue, hairs, hair follicles, sebaceous glands, and piloerector muscles developed in the graft. Two weeks after transplantation, TH-, SP-, and CGRP-immunoreactive fibers were observed in association with the blood vessels in the graft. Four weeks after transplantation, TH-immunoreactive fibers were distributed in the piloerector muscles, whereas SP-and CGRP-immunoreactive fibers were present around the hair follicles. VIP-immunoreactive and AchE-positive fibers were restricted to the host iris at all survival times. These results suggest that the outgrowth of autonomic and sensory nerve fibers from the host iris show target specificity for the grafted skin tissue.

    Notes: Abstract. It has been suggested that a matrix metalloproteinase, stromelysin-3 (ST3), is an important enzyme for epithelial transformation; the ST3 gene is known to be regulated by thyroid hormone during Xenopus metamorphosis. In this study, we have examined the distribution of ST3 mRNA in the small intestine of Xenopus during metamorphosis by using in situ hybridization. Around stage 58, ST3 mRNA is first detectable in larval fibroblasts near the muscular layer, and then increases in amount throughout the entire region of connective tissue. By stage 61, when connective tissue cells are rapidly increasing in number, ST3 mRNA is localized in fibroblasts just beneath the epithelium. This localization of ST3 mRNA is in good temporal accordance with modification of the basement membrane and epithelial transformation from the larval to adult form. Thereafter, ST3 mRNA gradually decreases and is no longer detected after stage 63 when the adult epithelium has completely replaced the larval type. The transient expression of ST3 mRNA in the fibroblasts of connective tissue during metamorphosis indicates that it plays an important role in epithelial transformation by changing the basement membrane.

    Notes: Abstract. Homozygotes of a mouse strain with genetic polydactyly (Pdn) show disrupted cortical lamination and a significant decrease of S-100β-immunoreactive elements in a particular area of the brain. In order to understand the abnormal cortical formation at the cellular level, the migration of cortical neurons and the development of glial cells were studied using bromodeoxyuridine (BrdU), S-100β, and glial fibrillary acidic protein (GFAP) immunohistochemistry. Homozygous mice (Pdn/Pdn) displayed a variable pattern of abnormalities. Irregular GFAP-positive radial glial cells and disturbance of neuronal migration were found in a circumscribed area of the caudo-dorsal cortex of newborn Pdn mouse. The number of S-100β-positive cells was reduced in this area. The present results suggest that abnormal cortical lamination closely correlates with disturbance of neuronal migration and abnormalities of glial cells, especially a significant decrease of S-100β-immunoreactive cells.

    Notes: Summary The distribution of serotonin-containing nerve fibers in the lateral geniculate nucleus (LGN) of the rat, cat, and monkey (Macaca fuscata) was studied by use of the peroxidase-antiperoxidase method and an antiserum against serotonin. In all three species, the pattern of fibers was denser in the ventral portion of the LGN (LGNv) than in the dorsal nuclear portion (LGNd). In the LGNd of rat, serotonin-immunoreactive fibers were evenly distributed in the form of a dense network, but in cat and monkey there were marked regional differences. Serotonin-immunoreactive elements were most numerous in the C complex and medial interlaminal nucleus of cat, and in the S layer and interlaminar zones of Macaca fuscata.

    Immunohistochemical study on fetal raphe samples transplanted into the leptomeningeal tissue of 5,6-dihydroxytryptamine-treated adult rats (1989)

    Notes: Summary Pieces of fetal midbrain raphe containing serotonergic and dopaminergic neurons were transplanted into the leptomeningeal tissue (see Fig. 3) of adult host rats that had previously been denervated by treatment with 5,6-dihydroxytryptamine. One, 2 and 5 months after transplantation, the rate of neuronal survival in the grafted tissue and the extent of axonal outgrowth into the host brain were studied by use of serotonin and tyrosine hydroxylase (TH) immunohistochemistry. The survival rate of the grafts in the 1-month group was approximately 70%. Neurons containing either serotonin or catecholamine were demonstrated by means of immunocytochemical procedures in the grafts. Two and 5 months after transplantation, serotonin-immunoreactive nerve fibers were densely distributed throughout the graft tissue, while TH-immunoreactive fiber elements were restricted to an area near the somata of TH-positive neurons. Numerous serotonin-immunoreactive fibers derived from the transplant were found in the leptomeningeal tissue surrounding the graft, on the wall of neighboring blood vessels, and also in the adjacent parenchyma of the host brain. Outgrowing TH-immunoreactive nerve fibers were not observed in the host brain, although such elements occurred in the leptomeningeal tissue and the wall of the larger blood vessels. These results suggest that the serotonergic and catecholaminergic (dopaminergic) neurons located in transplants of the raphe nuclei show different patterns when reinnervating the host tissue.

    Notes: Summary Pieces of fetal midbrain raphe tissue were transplanted into the third ventricle or the ventral hypothalamic region near the suprachiasmatic nucleus (SCN) of adult host rats that had previously been denervated by treatment with 5,6-dihydroxytryptamine. The ability of grafted serotonin neurons to reinnervate the SCN in the host rats was studied by means of immunohistochemistry 1 and 3 months after transplantation. In both the intraventricular and intraparenchymal transplant experiments, reinnervation by outgrowing serotonin fibers was observed in the hypothalamus of host rats at 1 and 3 months after surgery. At both survival periods, there was no abundant arborization of serotonin fibers in the SCN, while the preoptic and periventricular areas of the host rats displayed a pattern of serotonergic innervation resembling that in normal (untreated) rats. It is suggested that within the SCN the regenerating serotonin fibers may be exposed to an inhibitory environment.
