Comparative morphology of juxtaglomerular cells. I. Juxtaglomerular cells in fish

Abstract

By the use of the Bowie staining technique, juxtaglomerular cells or their homologues were identified in almost every member of Osteichthyes studied. Despite the fact that juxtaglomerular cells in the mammal, at least, belong to the sodium-retaining rennin–angiotensin–aldosterone system they occurred with frequency in salt-water as well as freshwater fish. Early evidence for the presence of renin in the kidney of certain freshwater fish was strengthened by the identification of granulated afferent arteriolar cells in the kidneys of these species. In an attempt to determine which structural components are necessary for the development of juxtaglomerular cells, their anatomical relationships in the fish were compared with the ones existing in higher forms.

The presence of a juxtaglomerular apparatus in elasmobranch fish

“…8a and b) as of other vertebrates, where they are also difficult to distinguish by conventional light microscopy (Biava andWest 1965, 1966;Biava 1967). Although Bowie's stain is traditionally used to identify JGG, it failed to reveal granules in the elasmobranch kidney, which is in agreement with previous observations of these chondrichthians (Capr6ol and Sutherland 1968;Sokabe et al 1969;Oguri et al 1970;Nishimura et al 1970;Crockett et al 1973 ;Lagios 1974). In some cartilagenous fish, actinopterygii (chondrosteans and holosteans), a renal renin or reninlike activity is present ) but JGG are either absent (Krishnamurthy and Bern 1969) or are not stained by the Bowie method (Ogawa et al 1972;Lagios 1974).…”

Immunohistochemical localization of S100‐like protein in non‐mammalian kidney

“…These authors demonstrated that among teleosts, there are at least six different JG cell distribution patterns, and that more than one type of pattern can occur in a single species. Furthermore, studies performed on various freshwater and saltwater fish kidney showed that the JG cells were present in both glomerular and aglomerular kidneys and along the renal afferent arterioles and arteries (Capreol and Sutherland, 1968;Oguri and Sokabe, 1968;Sokabe and Ogawa, 1974). In addition, the presence of secretory granules in JG cells indicates their endocrine nature (Bulger and Trump, 1968), and it is generally agreed that these cells are the site of the synthesis, storage, and release of renin in fish kidney (Elger and Hentschel, 1981;Elger et al, 1984;Henderson and Deacon, 1993;Kobayashi and Takei, 1996).…”

Distribution of Juxtaglomerular Cells in the Kidney of the Red Batfish.

“…The JG cells are also present in the teleostean kiddeys, and are detectable even in aglomerular fish. [6][7][8][9][10][11][12][13][14] For the aglomerular kidney the terminology of JG cells is not appropriate, but I have adopted this term in previous publications,8 -12,14) because JG cell is a well-known term for renin-containing cells in vertebrate kidneys. So I shall also use this term in the present report.…”
