Embodiment 1

[0041] Such as figure 1 As shown, an in vitro cell culture device includes a bioreactor 1, a dual culture solution irrigation system, a loading device and a monitoring system.

[0042] As shown in 2, the bioreactor 1 comprises a cover plate 11, a middle plate 12, a bottom plate 13 and a double culture cup 14, the cover plate 11 is placed on the middle plate 12, and the bottom plate 13 is placed on the Below the middle plate 12, the middle plate 12 is provided with a middle plate square hole 121, and a double culture cup 14 is placed in the middle plate square hole 121.

[0043] Such as Figure 3-5 As shown, the double culture cup 14 includes a square cup 141 and a round cup 142 inside the square cup 141 . The round cup 142 is composed of a round cup wall and a detachable round cup porous bottom sheet, and the round cup porous bottom sheet can allow culture fluid to pass through. The round cup 142 is provided with a round cup suction tube 144 and a round cup infusion tube 14...

Embodiment 2

[0053] In order to better understand the present invention, the method for culturing cells using the cell in vitro culture device described in Example 1 will be described below using only chondrocytes as an example, including the following steps:

[0054] S1. Prefabricating a liquid gel containing chondrocytes; in this embodiment, three-dimensional culture is used for chondrocytes, and any three-dimensional culture carrier in the prior art can be used;

[0055] S2. After assembling the bioreactor and the loading device, place it on the ultra-clean table, connect the computer to the motor, control the motor to adjust the position of the pressure plate so that there is a gap of 1-4mm between the porous pressure plate and the porous bottom plate of the round cup, and then Inject the liquid gel prefabricated in step S1 into the gap, make the liquid gel fully contact with the surface of the porous pressurized sheet and the porous bottom sheet of the round cup, and place at room temp...

Abstract

The invention discloses an in vitro cell culture device. The in vitro cell culture device comprises a bioreactor, a double nutrient solution irrigating system, a loading device and a monitoring system. The invention also discloses a method for culturing the cell by using the in vitro cell culture device. The method comprises the following steps: biologically simulating a physiological status, establishing the double nutrient solution irrigating system, and supplying different nutrients to different tissue blocks; allocating two pipe systems for each double culture cup, taking the culture tissue as a spacer layer of two culture solutions, culturing by simultaneously using two culture solutions, automatically irrigating the culture solutions, timely and quantificationally changing the cell culture solution, regulating the irrigating speed of the culture solution and constantly providing various nutrients and stable pH value for the cell. A dynamic pressurized environment is adopted for the cell culture device and the cell culture method; a pressure is exerted on the culture tissue by exerting a controllable axial compressive deformation load; the pressure and the compressive deformation of each culture tissue can be monitored and analyzed in real time and the pressure can be adjusted.

Description

technical field [0001] The invention relates to the field of in vitro cell culture, in particular to an in vitro cell culture device and a culture method. Background technique [0002] The proliferation, differentiation, and realization of physiological functions of cells or tissues are closely related to their environment, and these environmental factors can be one or more of nutrients, pressure, temperature, pH, etc. There are many tissues and cells in the human body that live in a dynamic load environment, such as chondrocytes and lung cells. Only when these tissues and cells are cultured under appropriate pressure conditions can they proliferate and differentiate normally and produce the same physiological functions as in vivo. Existing in vitro studies have shown that articular chondrocytes that are not cultured in vitro under appropriate pressure conditions have irregular cell arrangement, less matrix production, and thinner collagen fibers; at the same time, animal st...
