Abstract

The invention discloses a multi-cell co-culture model based on fiber hydrogel and a preparation method of the model. The multi-cell co-culture model comprises a multi-layer oriented nanofiber membraneand GelMA hydrogel which is poured into the multi-layer oriented nanofiber membrane to form gel and is of a three-dimensional porous structure. The multi-layer oriented nanofiber membrane can be prepared by utilizing an electrostatic spinning technology. By using the multi-cell co-culture model, a cell is inoculated on the multi-layer directional nanofiber membrane, a second cell is inoculated onthe upper surface of a fiber hydrogel stent, and a third cell is inoculated below the fiber hydrogel stent, so that in-vitro co-culture of various cells is realized. The multi-cell co-culture model not only can realize co-culture of multiple cells, but also has good mechanical properties and high bionic properties, and can provide structures and properties of extracellular matrixes capable of simulating natural tissues for the multiple cultured cells.

Description

technical field [0001] The invention relates to a multi-cell co-culture model, in particular to a fiber hydrogel-based multi-cell co-culture model and a preparation method thereof. Background technique [0002] Many tissues and organs in the human body are composed of a variety of cells. Different cells communicate with each other, influence each other, promote each other's biological behaviors such as proliferation and differentiation, and jointly maintain the homeostasis of tissues or organs. Therefore, constructing a multi-cell co-culture model in vitro can not only be a good bionic simulation, but also have better functionality. However, the traditional tissue engineering scaffolds can only achieve the culture of a single cell, which is far from enough to realize the in vitro biomimetic and simulation of the whole tissue or organ. Contents of the invention [0003] The purpose of the present invention is to provide a multi-cell co-culture model based on fiber hydrogel...
