Description

Technical Field

[0001] The utility model relates to the technical field of cell experiments, in particular to an observation and positioning device for cell experiments. Background Art

[0002] Biological cells generally refer to stem cells, which are a type of cell with unlimited or immortal self-renewal ability and can produce at least one type of highly differentiated daughter cells. The function of the 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 amplification 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. When conducting experimental observations on biological cells, the culture dish for culturing biological cells needs to be placed on an observation table, and fixed operations need to be performed, but the positioning mechanism on the existing observation table is relatively limited in adjustment and is not suitable for different culture dishes.
