Research Abstract

Through our studies aimed to establish novel methods to generate “bio-capsules” that are built by intestinal epithelial cells, we succeeded to identify a distinct culture condition, which allows us to produce “bio-capsules” in a highly efficient manner. In addition, we found that the capsules that were generated by the present method are consisted with high number of intestinal stem cells. Also, we confirmed that Rhodamine123, a substrate of P-glycoprotein, could easily accumulate within the inner space of the bio-capsule. These findings establish the basis for the efficient generation of drug-containing, intestinal epithelial cell-derived bio-capsules.
