Technical Field

[0001] The utility model relates to the technical field of cell culture, in particular to a human stem cell culture instrument. Background Art

[0002] The "stem" in stem cell (SC) is translated from the English word "stem", which means "stem", "dry" and "origin". The function of stem cell population is to control and maintain cell regeneration. Generally speaking, there is an intermediate progenitor cell population called "committed progenitor cells" between stem cells and their terminally differentiated daughter cells, which have limited expansion capacity and restricted differentiation potential. The function of these cell populations is to increase the number of differentiated cells produced after each division of stem cells. Stem cells have the ability to self-renew, but the division of stem cells is actually relatively asymmetric. Human stem cells have extremely broad application prospects in the fields of cell repair, developmental biology, pharmacology, etc. in life sciences.

[0003] Human stem cells are cultured using a culture instrument. However, existing human stem cell culture instruments are usually only able to culture human stem cells on a single culture dish, resulting in low culture efficiency.
