Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell centrifugation, specifically a centrifugation device for separating umbilical cord blood stem cells. Background Technology
[0002] Umbilical cord blood, as an important source of stem cells, has received widespread attention in the fields of regenerative medicine and cell therapy in recent years. Umbilical cord blood contains abundant hematopoietic stem cells and mesenchymal stem cells, which possess the potential for self-renewal and multi-lineage differentiation, and can be used to treat various blood and immune diseases. Therefore, how to efficiently and safely isolate stem cells from umbilical cord blood has become a hot research topic.
[0003] Currently, commonly used methods for stem cell isolation include density gradient centrifugation, flow cytometry, and immunomagnetic bead separation. Among these, density gradient centrifugation is widely used due to its simplicity and low cost. However, existing centrifugation devices have some shortcomings in the process of umbilical cord blood stem cell isolation.
[0004] If the rotating components fail to achieve balanced braking, the centrifugal effect will be mediocre. Utility Model Content
