Problems solved by technology

In the existing stem cell culture technology, culture on a petri dish, due to the uneven distribution of nutrients in the culture medium, stem cells will be enriched in places rich in nutrients during the growth process, which will lead to the growth of stem cells in the enriched place. Insufficient distribution of substances, the growth rate of stem cells will slow down, and in severe cases, stem cells will stop growing or even die

Abstract

The invention discloses a stem cell directional diffusion cultivation device. The cultivation device comprises a box body, a box door, a temperature control mechanism, an air exchange port, a humidity control mechanism and a directional diffusion mechanism, wherein the box body is of a hollow cubic structure with one open face, one side of the box door is movably connected to the open face of the box body, the air exchange port is formed in the box body, the temperature control mechanism is arranged in the box body, the humidity control mechanism is arranged in the box body, and the directional diffusion mechanism is arranged in the box body. According to the directional diffusion mechanism, valves are arranged at tail ends of the temperature control mechanism and the humidity control mechanism, then a temperature, humidity and O2 concentration in all directions of a culture dish are slightly changed by controlling opening and closing of the valves, then a growth moving direction of the cells can be controlled, the stem cells can automatically and uniformly grow in a directional mode, and survival rate is high.

Description

technical field [0001] The invention relates to the technical field of cell cultivation, in particular to a stem cell directional diffusion cultivation device. Background technique [0002] Neural stem cells are a kind of stem cells that exist in embryonic or adult brain, spinal cord and other tissues. They are a kind of mother cells with division potential and self-renewal ability, which can differentiate into neurons and astrocytes through unequal division. Various types of cells in nerve tissue, such as oligodendrocytes and oligodendrocytes, can also be transdifferentiated into blood cells and skeletal muscle cells. The current science and technology can already culture and expand neural stem cells in vitro. In the existing stem cell culture technology, culture on a petri dish, due to the uneven distribution of nutrients in the culture medium, stem cells will be enriched in places rich in nutrients during the growth process, which will lead to the growth of stem cells in ...
