Rat sperm AS-A: subcellular localization in testis and epididymis and surface distribution in epididymal sperm
Springer Science and Business Media LLC - Tập 318 - Trang 353-363 - 2004
Apichart Ngernsoungnern, Wattana Weerachatyanukul, Arpornrad Saewu, Siriporn Thitilertdecha, Prasert Sobhon, Prapee Sretarugsa
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-cycle
Springer 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 testis
Springer 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
Fasting differentially regulates expression of agouti-related peptide, pro-opiomelanocortin, prepro-orexin, and vasoactive intestinal polypeptide mRNAs in the hypothalamus of Japanese quail
Springer Science and Business Media LLC - Tập 313 Số 2 - Trang 217-225 - 2003
D. Phillips-Singh, Q. Li, Sakae Tanaka, Tadayasu Ohkubo, P. J. Sharp, Timothy Boswell
Phase-contrast microscopy of fresh and cultured pancreatic islet cells of guinea-pigs
Springer 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
Enhancement of barrier function by overexpression of claudin-4 in tight junctions of submandibular gland cells

The spinal sympathetic preganglionic cell column in the puffer fish, Takifugu niphobles

Atrial natriuretic peptide (ANP): a study of ANP and its mRNA in cardiocytes, and of plasma ANP levels in non-obese diabetic mice
Springer 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

Immunolocalization of Na+,K+-ATPase in the organs of the branchial cavity of the European lobster Homarus gammarus (Crustacea, Decapoda)
Springer Science and Business Media LLC - Tập 296 - Trang 417-426 - 1999
Jean-Hervé Lignot, Mireille Charmantier-Daures, G. Charmantier
The localization of Na+,K+-ATPase in epithelia of the organs of the branchial cavity of Homarus gammarus exposed to seawater and dilute seawater was examined by immunofluorescence microscopy and immunogold electron microscopy with a monoclonal antibody IgGα5 raised against the avian α-subunit of the Na+,K+-ATPase. In juveniles held in seawater, fluorescent staining was observed only in the epithe...... hiện toàn bộ
