“…The present study showed that in P. clarkii, adluminal epithelium composed of columnar cells which have oval basal nuclei with condensed chromatin, there is no conspicuous basement membrane at the epithelium-connective tissue interface. Same observation was recorded by To et al (2004) and Sousa and Petriella (2006) [42]. The latter described the hindgut of Palaemonetes argentinus which resembles that of P. clarkii.…”

“…The presence of these macromolecules has been mentioned in several decapod species, and they seem not to be associated with digestive processes (Lovett and Felder, 1990 [48]; Johnston and Alexander, 1999 [49]). According to Mary & Krishnan (1974) [50]; Malley (1977) [51]; Mykles (1979) [29] and Johnson (1980) [46] Sousa and Petriella, (2006) [42], the cuticles in decapod crustaceans are permeable to water and salts and they may allow the transport of both water and ions. In P. clarkii, the presence of mucosubstances protects the epithelial surface and forms a resistant barrier.…”

Procambarus clarkii is a freshwater crustacean which spread all over the River Nile. It has become an important crustacean model organism in research on animal behaviour, environmental stress, toxicity and its economic role. Ultraviolet radiation (UVR) has negative effects on aquatic organisms. The present study was designed to evaluate the effects of UV-A irradiation on the intestine of the crayfish Procambarus clarkii. To carry out the investigation, specimens were firstly adapted in the Lab, then classified into three groups. The first group was chosen as the control (untreated group) and the other two groups were the treated ones. The first treated group was irradiated for 15 minutes of UV-A for two weeks while the second treated group was irradiated for 30 minutes of UV-A for two weeks. Each treated group was lifted for two weeks for recovery after irradiation. After treatments, the intestine including circular and longitudinal muscles were examined. The structural integrity of the epithelium and myoepithelium of the intestine of the control and treated groups were assessed using histological, histochemical and electron microscopic techniques. The significance changes of histological and histochemical were observed in treated animal and discussed. The study revealed that after 15 min. of UV-A irradiation for two weeks, P. clarkii showed signs of damage of intestine and the damage increased with increasing the time of irradiation for 30 min. The damage included intestinal epithelial cells with cell membrane, irregular structure of cuticular layer and absence of organoids seen by electron microscopy. These necrotic effects of UV-A in intestinal cells in irradiated animals may cause lethal lesions. Incomplete recovery was observed in each group.

“…E‐cells in the adult hepatopancreas have been described as stem cells, which can proliferate and differentiate in the medial zone into F‐ and B‐cells (Sonakowska et al, 2015). In Crustacea, these cells have been described (Arnaud, Brunet, & Mazza, 1978; Muskó, 1988; Ceccaldi, 1989; Vogt, 1993, 1994; Vogt, Stocker, & Zwilling, 1989; Sousa & Petriella, 2001; Sonakowska et al, 2015; Štrus et al, 2019; Vogt, 2019) as small cells located between the basal regions of other epithelial cells (Sousa, Cuartas, & Petriella, 2005; Sousa & Petriella, 2000, 2006). They correspond to midgut regenerative cells ‐ midgut stem cells of other arthropods (Fernandes, Neves, Serrão, & Martins, 2014; Gonçalves et al, 2014; Hakim, Baldwin, & Smagghe, 2010; Rost‐Roszkowska, Jansta, & Vilimova, 2010; Sosinka et al, 2014).…”

“…The digestive tract functions in ingestion of food, transit of food items, mechanical digestion, chemical and biochemical hydrolysis, cellular absorption and transfer of excreta (Ceccaldi, 1989). The digestive system of malacostracan Crustacea is composed of the tube‐shaped ectodermal fore‐ and hindgut, while the endodermal midgut can be differentiated into the intestine and hepatopancreas (Herrera‐Alvarez, Fernandez, Benito, & Pardos, 2000; Sousa & Petriella, 2006; Trevisan et al, 2014; Sacristán, Nolasco‐Soria, & López Greco, 2014; Sacristán, Ansaldo, Franco‐Tadic, Fernández Gimenez, & López Greco, 2016; Sonakowska et al, 2015; Cervellione, McGurk, Silva, Owen, & Broeck, 2017; Štrus et al, 2008, Štrus, Žnidaršič, Mrak, Bogataj, & Vogt, 2019; Vogt, 2019, 2020). A wide range of studies has been conducted on the structure and function of the cardiac stomach, especially the gastric mill in decapods (Dall, 1967; Factor, 1981, 1995; Felgenhauer & Abelle, 1989; Johnston, Johnston, & Knott, 2008; Sousa & Petriella, 2006; Suthers, 1984).…”

Neocaridina davidi is a freshwater shrimp that originates from Taiwan and is commonly bred all over the word. Like all decapods, which develop indirectly, this species has pelagic larvae that may differ entirely in their morphology and habits from adult specimens. To fill a gap of knowledge about the developmental biology of freshwater shrimps we decided to document the 3D-localization of the midgut inside the body cavity of larval stages of N. davidi using X-ray microtomography, and to describe all structural and ultrastructural changes of the midgut epithelium (intestine and hepatopancreas) which occur during postembryonic development of N. davidi using light and transmission electron microscopy. We laid emphasis on stem cell functioning and cell death processes connected with differentiation. Our study revealed that while the intestine in both larval stages of N. davidi has the form of a fully developed organ, which resembles that of adult specimens, the hepatopancreas undergoes elongation and differentiation. E-cells, which are midgut stem cells, due to their proliferation and differentiation are responsible for the above-mentioned processes. Our study revealed that apoptosis is a common process in both larval stages of N. davidi in the intestine and proximal region of the hepatopancreas. In zoea III, autophagy as a survival factor is activated in order to protect cells against their death. However, when there are too many autophagic structures in epithelial cells, necrosis as passive cell death is activated. The presence of all types of cell death in the midgut in the zoea III stage confirms that this part of the digestive tract is fully developed and functional. Here, we present the first description of apoptosis, autophagy and necrosis in the digestive system of larval stages of Malacostraca and present the first description of their hepatopancreas elongation and differentiation due to midgut stem cell functioning.

“…The intestine is a tubular organ that originates after the junction between the hepatopancreas and the stomach (Icely and Nott, 1992) and transports the processed contents in the hepatopancreas to the hindgut. Its main function is the regulation and transport of ions and water (Felder and Felgenhauer, 1993;De Jong-Moreau et al, 2000;Sousa and Petriella, 2006).…”

Histology of the hepatopancreas and anterior intestine in the freshwater prawn Macrobrachium carcinus (Crustacea, Decapoda)

The purpose of this study was to describe the structure of the midgut (hepatopancreas and intestine) in the endemic species, Macrobrachium carcinus. Thirty specimens were collected, and the midgut was fixed in Bouin's solution for histological and histochemical analyzes by light microscopy. The hepatopancreas consists of two lobes that connect to the end of the stomach by primary ducts, which originate secondary tubules or hepatopancreatic ducts, that branch into hepatopancreatic tubules. The hepatopancreatic duct presents a columnar epithelium composed of R-and F-cells with evident brush borders for absorption and storage. The hepatopancreatic tubule is lined by epithelium with five cell types (E, F, R, B, and M). The distal region presents all cell types, with a predominance of E-cells that correspond to epithelial renewal. The middle region presents F-and B-cells, characteristic of extracellular and intracellular digestion. The proximal region, with B-and R-cells, performs the final digestion, storage, and extrusion of the cells with
