Canine Intestinal Organoids in a Dual-Chamber Permeable Support System
March 2nd, 2022
Here, we present a protocol describing the culture of canine intestinal organoids in a dual-chamber, permeable support system. Organoid seeding in the permeable supports, the monolayer maintenance, and subsequent drug permeability experiments are described.
The combination of canine organoid technology and a dual chamber permeable support system overcomes the limitations of experimental 2D cell lines traditionally used in biomedical research models.The technology can increase the reliability of predictions of the apparent oral permeability of therapeutic drug candidates both in canine and human patients.The system can be applied to other fields of biomedical research including microbiology research, viral uptake studies, drug-drug interactions, and drug transport mechanisms.The standardization, detailed documentation of experimental procedures and consistent monitoring of the cell monolayers are crucial practices needed for the permeable support assays.Place the extracellular membrane matrix on ice to begin thawing.Submerge it in ice to protect against rapid thawing and avoid solidification.Pre-chill a refrigerated centrifuge to 4
