Robust Three-Dimensional (3D) Expansion of Bovine Intestinal Organoids: An In Vitro Model as a Potential Alternative to an In Vivo System
Abstract
Simple Summary The ability to recapitulate stem cells’ self-organising potential, creating three-dimensional (3D) structures of stem cells, has revolutionised various fields. Recently, in vitro 3D organoid systems are now used as alternative research tools because they serve the same purpose as in vivo systems. In the present study, we developed bovine intestinal organoids based on a 3D culture system and evaluated their characteristics. These bovine intestinal organoids, used in an in vitro model as a potential alternative to an in vivo system, hold great promise for further potential use in determining disease-modelling-based host–pathogen interactions and nutritional research for feed efficiency measurements. Abstract Intestinal organoids offer great promise for disease-modelling-based host–pathogen interactions and nutritional research for feed efficiency measurement in livestock and regenerative medicine for therapeutic purposes. However, very limited studies are available on the functional characterisation and three-dimensional (3D) expansion of adult stem cells in livestock species compared to other species. Intestinal crypts derived from intestinal organoids under a 3D culture system from the small intestine in adult bovine were successfully established and characterised for functionality testing, including the cellular potentials and genetic properties based on immunohistochemistry, immunocytochemistry, epithelial barrier permeability assay, QuantSeq 3′ mRNA-Seq.…
