In immature animals, the cells of the coelomosac are likened to the vertebrate podocyte in that it has a flattened shape and small vacuoles as well as pinocytotic vesicles. Podocytes in mature crayfish have various sizes of vesicles in the cytoplasm, and they have elongated shapes. Our SEM observations show "blebs” as sections of the long elongated head of a podocyte, which push each other in the urinary space. Podocytes have long projections which are connected to each other via slit membranes. Wide space is required for podocytes, and they may secure the space needed to absorb the necessary materials that pass through the slit membrane and basal lamina. The morphological differences between the podocytes of mature and immature crayfish may reflect the amounts of metabolic waste. This reinforces the suggestion that in decapoda, podocytes have a very active function in the secretion and reabsorption of large molecules. © 1996 Oxford University Press Full-length Papers nationallicence podocytes nationallicence crayfish nationallicence antennal glands nationallicence kidney nationallicence coelomosac nationallicence Ueno Masaki School of Allied Health Sciences, Kitasato University, 1-15-1, Kitato, Sagamihara, Kanagawa, 228 Japan aut Inoue Yoshiko School of Allied Health Sciences, Kitasato University, 1-15-1, Kitato, Sagamihara, Kanagawa, 228 Japan aut Microscopy Oxford University Press 45/5(1996-10), 395-400 0022-0744 45:5<395 1996 45 jmicro https://doi.org/10.1093/oxfordjournals.jmicro.a023457 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/oxfordjournals.jmicro.a023457 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Ueno Masaki School of Allied Health Sciences, Kitasato University, 1-15-1, Kitato, Sagamihara, Kanagawa, 228 Japan aut NATIONALLICENCE 700 1- Inoue Yoshiko School of Allied Health Sciences, Kitasato University, 1-15-1, Kitato, Sagamihara, Kanagawa, 228 Japan aut NATIONALLICENCE 773 0- Microscopy Oxford University Press 45/5(1996-10), 395-400 0022-0744 45:5<395 1996 45 jmicro Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
