[0002] Stem cell research plays an extremely important role in the field of modern biomedicine; stem cells have the ability of self-renewal and differentiation into multiple cell types, bringing great hope for disease treatment, tissue repair and regenerative medicine; in the process of culturing stem cells, culture plates are indispensable tools; with the continuous in-depth research and expanding application scope of stem cells, the requirements for stem cell culture plates are also increasing day by day; traditional single-layer culture plates have limitations such as low space utilization rate and low culture efficiency when dealing with the culture needs of a large number of stem cells; in order to meet the needs of large-scale and efficient stem cell culture, multi-layer assembled stem cell culture plates have emerged.

[0003] However, in the actual application of existing multi-layer assembled stem cell culture plates, due to the complexity of the multi-layer structure, the friction between layers and the mutual extrusion effect, operators need to apply a large amount of force when separating or pulling out the lower culture plate; this laborious operation not only increases the work intensity and reduces the operation efficiency, but also easily causes the culture plate to be suddenly pulled out or stuck due to uneven force application, which has an adverse impact on the internal cell culture environment and may even affect the growth and development of cells; especially in the case of frequent operations or dealing with multiple culture plates, this problem is more prominent, seriously restricting the smooth progress of stem cell culture work. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a multi-layer assembled stem cell culture plate to solve the technical problems of laborious manual operation; as well as the inconvenient connection and operation between the side plate and the connecting block.
