The invention discloses a construction method for a human intestinal tract epithelial cell model, and relates to the technical field of cell model construction. The human intestinal tract epithelial cell model is characterized in that a Caco-2 cell is taken as a model cell, and a DMEM (dulbecco's modified eagle medium) containing 20%FBS (fetal calf serum) is used for carrying out 3D culture on theCaco-2 cell in a micro-fluidic chip so as to construct the in vitro model of the human intestinal tract epithelial cell. On one hand, a human cell is adopted for culture, the problem that an experiment result is in accurate since an animal cell is adopted for culture is avoided, and on the other hand, the 3D cell culture enables intestinal tract cells to own a mechanical microenvironment which ismore similar to the human physiology, so that intestinal tract cells can be accelerated to differentiate. Therefore, the human intestinal tract epithelial cell model constructed by the construction method disclosed by the invention can more clearly and accurately reflect the characteristics of small intestine epithelial barriers.
