The vast majority of FL (85%) have at least in part a follicular growth pattern, are composed of centrocytes and centroblasts and harbour the t(14;18)(q32;q21) translocation associated with IGH::BCL2 fusion; these are now termed classic FL (cFL) and set apart from two related ...
A substance consumed by female larvae has been known to be a factor affecting caste determination ofMeliponagenus, in which queens are genetically determined (Kerr1950; Brito et al.2015). It was suggested that a cohort of adult bees (nurse workers) could apparently coerce female larva to become...
The cells lining the crypts are composed of variable numbers of goblet cells and cells with abundant fine apical vacuoles with microvesicular mucin (Fig. 1). In most cases, the microvesicular cells predominate. The nuclei of the surface epithelium are small, round to oval, and basally located...
All spider silk threads are mainly composed of one or more proteins, called spidroins, which tend to be large (up to 350 kDa per monomer)14. Despite their different properties, all spidroins share a common primary structure pattern comprising a large central core of repeated modular units, ac...
The so-called cardiac glands are composed of the compound tubular glands and simple or simple branched tubular glands.3. A few parietal cells are found in the cardiac, upper and lower esophageal cardiac glands.4. Pepsinogen granules can be found in the basal, body and neck portions of the ...
Salivary glands are composed of two types of secretory acinar cells surrounded by myoepithelial cells that help the secretion of the mucous or serous fluid into the ductal network through which saliva reaches the oral cavity (Fig.1)26,27,28. ...
The pollen walls maintain pollen structure, provide protection from various environmental stresses and preserve pollen germination [36]. Previous studies have found that pollen walls were the most intricate cell walls in plants. They are composed of exine and intine layers that are formed in a comp...
Stonefishhave 13 sharp fin spines on their back, each with two venom glands. Their stings are extremely painful, can be lethal to humans, and mostly occur as a result of stepping on the creature. 47. Only 5% of cheetah cubs survive to adulthood. ...

Although the walls of the gastric pits are made up primarily of mucus cells, the gastric glands are made up of different types of cells. The glands of the cardia and pylorus are composed primarily of mucus-secreting cells. Cells that make up the pyloric antrum secrete mucus and a number of...
