Renal haemopoietic tissue of the mudskipper Periopthalmus koelreuteri (Pallas)

Abstract

The renal haemopoietic tissue of the mudskipper Periophthalmus koelreuteri was examined by light and electron microscopy. Leukopoietic zone surrounding melanomacrophage center and erythropoietic zone were differentiated. The ultrastructural features of the cellular components of the haemopoietic compartments are similar to those described in other fishes. Despite the presence of lymphoid cells, this tissue is mainly myeloid, and active granulopoiesis and erythropoiesis occur, as in the red bone marrow of higher vertebrates. © 1992 Wiley-Liss, Inc.

Morphocytochemical, immunohistochemical and ultrastructural characterization of the head kidney of fat snook Centropomus parallelus

“…There are few reports that describe the morphocytochemical and ultrastructural aspects of the groups of haematopoietic cells (Zuasti & Ferrer, 1988, 1989; Esteban et al , 1989; Meseguer et al , 1990; El‐Sayed & Safer, 1992; Fijan, 2002; Petrie‐Hanson & Peterman, 2006), and of the cellular and extracellular components that constitute the stromal cytofibrillary network of the head kidney (Smith et al , 1970; Zapata, 1983; Tatner & Manning, 1985; Meseguer et al , 1991, 1995). The ultrastructural characterization of the capsule and description of its inter‐relation with the constituents of the subcapsular region of the head kidney have not been described.…”
