[0002] Stem cells are a type of multipotent cells with the ability to self-renew and self-replicate. Stem cells can be divided into embryonic stem cells and adult stem cells. According to different differentiation potentials, they can be divided into totipotent stem cells, pluripotent stem cells, and unipotent stem cells. They have multidirectional differentiation potential, unlimited division, and proliferation. Stem cells need to be shaken before use, so an oscillation device will be used. The stem cell oscillation device is an important innovation in the field of biotechnology, especially in the process of stem cell culture and expansion. It plays an indispensable role in adjusting the frequency and intensity of the oscillation to ensure that stem cells are cultured and expanded in the best state. The oscillation technology provides a stable and uniform growth environment for stem cells, which effectively promotes the division and proliferation of stem cells. The oscillation device can simulate the natural growth environment of cells in the body and provide the best living conditions for stem cells.
