“…Quails show many advantages over other birds, as small birds grow easily and rapidly and are capable of egg production within 2 months of age (Soliman et al, 2016; El-Desoky & Mustafa, 2019). The spleen of birds is a very important immune organ in birds due to ill-developed lymph nodes and vessels in avian species (Kita, 2014).…”

The spleen is considered a key player in birds’ immunity. The stroma and the parenchyma of the spleen of the adult quail were demonstrated histologically, histochemically, and ultrastructurally. A thin capsule and the absence of trabeculae were the most characteristics of spleen stroma. The demarcation between white pulp and red pulp was not observed in the quail. White pulp formed from the periarterial lymphatic sheath and the periellipsoidal lymphatic sheath, both of which were surrounded by arteriole and ellipsoid, respectively. Ellipsoids appeared more numerous and were characterized by cuboidal lining of the epithelium and supporting cells. Red pulp consisted of sinuses and cords. White pulp and red pulp of the quail spleen contained various cells, such as red blood cells, macrophages, heterophils with characteristic granules, lymphocytes of different sizes, dendritic cells, plasma cells, and telocytes. In addition, closed circulation and open circulation established the blood flow on the spleen.

“…The samples were processed for paraffin block preparation according to the methods of Soliman et al (2016); Soliman (2018 a , 2018 b ); Soliman & Abd-Elhafeez (2018); and El-Desoky & Mustafa (2019). The samples were dehydrated in 70% ethanol baths I, II, and III for 1 day in each bath; an 80% ethanol bath for 2 h; a 90% ethanol bath for 1 h; and 100% ethanol baths I and II for half an hour each.…”

Morphological and Histochemical Characterization of the Dermal Plates of Pleco (Hypostomus plecostomus)

Studying the dermal skeleton in fish is valuable for phylogenetic specification. The current study describes the detailed structure of the plecostomus dermal skeleton, including its morphogenesis and distribution in the skin. The denticles have a crown and a basal part and are embedded in bony depressions, to which they are attached by denticle ligaments. During denticle morphogenesis, denticle papillae formed from denticle precursor cells align in two cellular layers: an outer ameloblast precursor layer and an inner odontoblast precursor layer. The ameloblast precursors and odontoblast precursors differentiate and secrete enamel and dentine, respectively. We used different histochemical techniques, including Crossmon's trichrome staining, Weigert–Van Gieson staining, periodic acid–Schiff (PAS) staining, combined Alcian blue (AB; pH 2.5)/PAS staining, Weigert–Van Gieson staining, Mallory trichrome staining, and AB staining to distinguish the dentine and denticle ligaments. We used acridine orange to detect lysosome activity during denticle eruption. Transmission electron microscopy was used to detect the denticle ultrastructure, and scanning electron microscopy was used to detect the topographic distributions of different types of dermal tissues in different anatomical regions.

“…Additionally, the PVS is considered another anatomical system similar to the blood and lymphatic systems but differs from them in some aspects (Kim et al, 2016; Noh, Rho, Yoo, Jung, & Lee, 2012; Soh, 2009). Regarding the vascular system, special types of blood vessels were newly discovered (El‐Desoky & Mustafa, 2019; Hussein, 2019). Although the lymphatic system is of great importance, until now, its structure network is not fully understood (Kim et al, 2016; Sevick‐Muraca, Kwon, & Rasmussen, 2014; Weiler, Kassis, & Brandon Dixon, 2012).…”

The primo vascular system (PVS) is observed in different parts of the body under different physiological and disease conditions. Previously, the PVS was not observed in the vagina. The vaginal samples of this study were collected from the female genitalia of healthy New Zealand white rabbits from the animal house, Faculty of Medicine, Assiut University. The vaginal samples were fixed in Bouin's solution. The sections were stained with hematoxylin and eosin and Crossmon's trichrome. Additionally, the sections were immunohistochemically stained with neuron‐specific enolase (NSE) and vascular endothelial growth factor (VEGF). A primo node was observed on the lymph vessel of the vagina and has several characteristics that resemble those of the previously discovered primo nodes. The primo node in this study was surrounded by mesothelial cells that provide positive immunoreactivity to NSE and VEGF. Sinuses of different sizes, floating cells, telocyte‐like cell, and primo microcells were observed as the main constituents of the primo node. Additionally, migratory cells were detected, which passed from the primo node to the enclosing lymph vessel.
