Description

Culture dish for non-contact cell co-culture
Technical Field
The utility model relates to a cell biology experiment technical field especially relates to a culture dish for non-contact type cell coculture.
Background
A technique of culturing cells taken out of the body in vitro in a manner simulating the physiological environment in the body and allowing them to survive and grow is called cell culture. Cell culture techniques are important and commonly used in cell biology research methods, and a large number of cells can be obtained through cell culture, and signal transduction, anabolism, growth and proliferation of cells and the like of the cells can be researched. The in vitro cell culture method includes adherent culture, semi-adherent culture, suspension culture, etc., and the adherent culture is the most common. When the cells are cultured in the adherent mode, the liquid culture medium not only can provide nutrient components for the growth and proliferation of the cells, but also can provide cytokines and the like necessary for maintaining the normal physiological functions of the cells, provides proper temperature, osmotic pressure, pH value and oxygen and carbon dioxide concentrations for the growth of the cells, and can be said to directly form the internal environment for the growth of the cells.
In the late stage of the 80's of the 20 th century, in order to establish a culture system more similar to the in vivo environment, the in vitro environment and the in vivo environment are matched as much as possible, so that the cells can communicate information with each other and support each other for growth and proliferation, and people develop a cell co-culture technology on the basis of the cell culture technology. The cell co-culture technique is to co-culture 2 or more cells in the same environment, and is widely applied to modern cell research due to the advantage of better reflecting the in vivo environment.
Cell co-culture systems are mainly established by two methods: 1. a direct co-culture system, namely 2 or more than 2 cells are simultaneously or respectively inoculated in the same hole, and different types of cells are in direct contact with each other, and different cells grow in the same cell container, so that various cells cannot be separated for the next research, and the application of the cells is limited; 2. an indirect co-culture system, i.e. 2 or more than 2 cells are respectively inoculated on different carriers, then the two carriers are placed in the same culture environment (liquid culture medium), so that different types of cells share the same culture system without direct contact, but such a culture system has requirements on the spacing between different carriers, if the operation is slightly shaken, the cells on one carrier can move to the other carrier, and the pollution and the mixing of different cells are caused; in addition, the culture system is only suitable for adherent cells and is not suitable for the culture of suspension and semi-suspension cells.
In addition, the existing cell co-culture system has a small maximum number of cells that can be cultured in one culture, and it is difficult to collect enough cells for experiments requiring a large number of cells such as flow cytometry, a model for animal transplantation of cells, and the like.
