[0002] Mesenchymal stem cells are a type of pluripotent stem cells that have all the common properties of stem cells, namely, self-renewal and multidirectional differentiation capabilities. They are also the most widely used in clinical applications. When used in combination with hematopoietic stem cells, they can improve the success rate of transplantation and accelerate hematopoietic reconstruction. When patients receive high-dose chemotherapy, the infusion of mesenchymal stem cells together with hematopoietic stem cells can significantly accelerate the recovery time of the patient's blood cells, and it is safe and has no adverse reactions. When sampling mesenchymal stem cells, a centrifugal device is required for centrifugal sampling. Before centrifugal sampling, the fat tissue needs to be cut into pieces.
