Embodiment 1

[0050] Embodiment 1: Preparation of the cell culture device of the present invention

[0051] The cell culture device used is composed of an upper substrate, a thin film and a lower substrate, forming a "sandwich" structure between the three. The upper base plate and the lower base plate are made of polystyrene material, and the appearance is a circular plate with a diameter of 3.3 cm. There are 120 connected cylindrical through holes on the upper substrate and the lower substrate respectively, the depth of the holes is 2 mm, and the diameter of the holes is 2 mm. There are four small cylinders on the lower surface of the upper substrate and the lower substrate respectively, with a height of 2mm and a diameter of 1.5mm. The upper surfaces of the upper substrate and the lower substrate each have four holes corresponding to the size and height of the small cylinders, so as to clamp the film . The film is a polyethylene terephthalate film (PET) with a pore size of 8 μm. The de...

Embodiment 2

[0052] Embodiment 2: Inoculation of NIH-3T3 cells

[0053] 1. Vaccination

[0054] Place the cell culture device prepared in Example 1 in a petri dish with a diameter of 35mm, and add a concentration of 2×10 6 NIH-3T3 cell suspension per mL, after the cell suspension penetrates into the well, add fresh medium from the side channel. The medium is flush with, but does not cover, the top surface of the device. After the cells attach to the wall, fresh medium is slightly added to cover the entire cell culture device for culture.

[0055] 2. Detachment

[0056] Place the culture dish equipped with the cell culture device at an ambient temperature of about 20 degrees Celsius for 10 minutes, and then observe the detached cell mass under a microscope ( Image 6 ), the cells in each well are aspirated and mechanically blown gently, which can be used for subsequent detection or expanded culture.

Embodiment 3

[0057] Example 3: Co-cultivation of adherent cell NIH-3T3 and cell HL-60

[0058] The size of the cell culture device used was the same as in Example 1, except that the middle membrane was replaced by a polycarbonate membrane with a pore size of 5 μm. The surface of the film was not treated, and the upper substrate, film and lower substrate were assembled together, soaked in 75% ethanol for sterilization, and air-dried in an ultra-clean bench.

[0059] Set the concentration to 2 x 10 6 NIH-3T3 cells / mL were inoculated on the bottom of a 35 mm-diameter petri dish. After 24 hours, the medium was removed and the surface was rinsed with PBS. Then put the sterilized and air-dried above-mentioned cell culture device into it, and put the concentration of 2×10 5 Each / mL HL-60 cell suspension was dropped on the surface of the device, and after the cell suspension completely penetrated into the well, fresh medium was added from the side channel. The total volume of medium is flush wi...

Abstract

The invention provides a cell culture apparatus or a cell co-culture apparatus. The apparatus comprises a permeable thin layer provided with an upper surface and a lower surface which are used for the inoculation and growth of the cell thereon. Different cells are inoculated and cultured on the upper surface and the lower surface. The invention also provides a method for culturing two or more varieties of cells. The invention also provides a method for measuring short-range interaction between cells and cells.

Description

technical field [0001] The present invention relates generally to the fields of biology and medicine. In particular, the invention relates to cell culture, especially co-culture of multiple cells. Background technique [0002] Cell culture is an important technology in the fields of biology and medicine, and its purpose is to make cells grow and proliferate under in vitro conditions. [0003] The most widely used form of cell culture is the cultivation of one cell in a suitable medium in a culture vessel, such as a monolayer culture. The disadvantage of this culture is that it cannot accurately simulate the real environment of cells in vivo. For example, such cultures fail to enable communication between different cell types, which can have important effects on cell properties in an in vivo environment. [0004] In order to make the in vitro cell culture environment as close as possible to the real environment in vivo, people have developed multi-cell co-culture technolog...
