Avian ceca play an important role in liquid absorption, cellulose digestion, and defensive mechanism. This study aims to demonstrate histological and histochemical characteristics of developing chicken cecum. For this purpose, 10 embryos on the 18th day of incubation, 10 chicks on hatching day and 10 chicks on the seventh day post-hatching were used.

Morphofunctional characteristics of the large intestine are rarely explored to understand the physiology, behavior and ecology of neotropical primates. In this study, we analyzed the histometric parameters of the large intestine of hybrid marmosets (Callithrix sp.) captured in forest fragments of Viçosa-Brazil, under seasonal interference.

Background: Probiotics and zinc are commonly used and beneficial in pig production. This work aimed to assess the effects of probiotic and zinc on the mucosal cells of the small intestine in respect to digestive capacity and immunity in pre- and post-weaned piglets.
Materials And Methods: Eighteen Large White Yorkshire piglets were divided equally into control and treatment groups.
Three-dimensional bioprinting collagen/silk fibroin scaffold combined with neural stem cells promotes nerve regeneration after spinal cord injury.

Many studies have shown that bio-scaffolds have important value for promoting axonal regeneration of injured spinal cord. Indeed, cell transplantation and bio-scaffold implantation are considered to be effective methods for neural regeneration. This study was designed to fabricate a type of three-dimensional collagen/silk fibroin scaffold (3D-CF) with cavities that simulate the anatomy of normal spinal cord.

The small intestinal villus and its associated epithelium includes enterocytes as the main cell type and differentiated goblet and argentaffin cells, while the invaginated crypt epithelium is the site of cell division and hence the origin of all epithelial components. Enterocytes form a cohesive monolayer which acts both as a permeability barrier between lumen and the interior, and an important gateway for nutrient digestion, absorption and transport. Differentiation and polarisation of enterocytes depends on cytoskeletal proteins that control cell shape and maintain functionally specialised membrane domains; extracellular matrix (ECM) receptors; channels and transporters regulating ion/solute transfer across the cell.
