Description

Technical Field

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

[0002] Stem cells 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. They 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.

[0003] When sampling stem cells, the stem cells must first be separated from the blood. Currently, when sampling stem cells, most of the blood is shaken and then centrifuged together after the shaking is completed. This requires multiple devices and is cumbersome to operate, which reduces the efficiency of stem cell sampling by medical staff. To this end, we propose a stem cell sampling device to solve the above problem. Utility Model Content
