2D (two-dimensional) monolayers of Caco-2 cells, on Transwell inserts, have been widely employed to assess drug permeability and absorption of drugs across the intestine. However, 3D (three-dimensional) in vitro tissue models are more physiological relevant as they can simulate interactions with the extracellular matrix and, therefore, better recapitulate the complex in vivo intestinal tissue environment [1–5]. Thus, the characteristics of these Caco-2 spheroids, including their barrier function, potential changes in cell phenotype and transport function, need to be well-understood. With this motivation, we designed a 3D-printed device to culture geometrically controlled Caco-2 spheroids. Furthermore, we developed the device to enable the perfusion of medium to overcome the limitation in cell-construct size due to mass exchange. We conduct a comparative study to evaluate static and dynamic conditions to validate the advantage of spheroid culture with perfusion. This alternative in vitro intestinal model will serve as a valuable system to expedite drug screening as well as to study intestinal transporter function.
