Rat sperm AS-A: subcellular localization in testis and epididymis and surface distribution in epididymal spermSpringer Science and Business Media LLC - Tập 318 - Trang 353-363 - 2004

In this study, we investigated the subcellular compartmentalization of arylsulfatase-A (AS-A) in the testis and epididymis as well as the surface distribution in rat epididymal sperm. Testicular AS-A was compartmentalized specifically to the area underneath the outer acrosomal membrane of the acrosomal granule and to the dorsal aspect of the sperm acrosome. Epididymal AS-A was synthesized in the e...... hiện toàn bộ
Cell types in the pituitary of the eel, Anguilla anguilla L., at different stages in the life-cycleSpringer Science and Business Media LLC - Tập 69 - Trang 474-479 - 1966
Francis Knowles, Lutz Vollrath
Striking differences in certain cell-types in the pituitary of the eel at different stages of the life-cycle indicate their possible function. One type, suspected of GTH function, was not present in the elver but present in the young adults and vacuolated in older adults just prior to migration; these changes accompany stages in the development of the gonads. Others, characterised as STH and TSH c...... hiện toàn bộ
Immunohistochemical localization of a water channel, aquaporin 7 (AQP7), in the rat testisSpringer Science and Business Media LLC - Tập 295 - Trang 279-285 - 1999
F. Suzuki-Toyota, K. Ishibashi, S. Yuasa
Cell volume reduction is one of the most distinct morphological changes during spermiogenesis and may be largely attributable to water efflux from the cell. A strong candidate for a water efflux route, aquaporin 7 (AQP7), which is a water channel, was studied immunohistochemically in the rat testis. Immunoreactivity was restricted within the elongated spermatids, testicular spermatozoa, and resid...... hiện toàn bộ
Phase-contrast microscopy of fresh and cultured pancreatic islet cells of guinea-pigsSpringer Science and Business Media LLC - Tập 82 - Trang 110-117 - 1967
Arne Andersson, Claes Hellerström, Birger Petersson
Isolated cells were prepared from microdissected pancreatic islets of guinea-pigs. Phase-contrast microscopy of the fresh islet cells suspended in a balanced salt solution displayed a number of cellular details, including cytoplasmic secretion granules. There was morphologic evidence of the survival of islet cells in monolayer cultures for up to 3 weeks. A moderate proliferation of cells occurred ...... hiện toàn bộ
Atrial natriuretic peptide (ANP): a study of ANP and its mRNA in cardiocytes, and of plasma ANP levels in non-obese diabetic miceSpringer Science and Business Media LLC - Tập 267 - Trang 267-272 - 1992
Hiroharu Mifune, Syusaku Suzuki, Junichi Honda, Yuta Kobayashi, Yasutaka Noda, Yoshihiro Hayashi, Koshi Mochizuki
Atrial natriuretic peptide (ANP) levels in cardiocytes and plasma were examined by using immunohistochemistry, electron microscopy, and radioimmunoassay in non-obese diabetic mice (NOD). Cardiocyte ANP mRNA expression was measured by the polymerase chain reaction method. ANP immunoreactivity in the auricular cardiocytes was more prominent in hyperglycemic mice (NOD-h) than in normoglycemic mice (N...... hiện toàn bộ
