Background

Stromal vascular fraction cells (SVFs) are derived from human Adipose tissue, are rich in Adipose-derived stem/stromal cells (ADSCs), vascular endothelial cells and progenitor cells thereof, and are increasingly gaining attention worldwide for application in the field of stem cell research and clinical treatment. The autologous granular fat transplantation can be used for the purposes of repairing soft tissue defects, losing fat and rejuvenating organs such as the face, is an epidemic operation type in the field of cosmetic surgery, and also provides a promising means for plastic repair and treatment of diseases. However, the survival after fat transplantation is unstable, and the long-term retention rate is reported to be between 20 and 80 percent in the literature, and complications such as fat liquefaction, cyst, calcification and the like can be caused due to non-survival. The conventional SVFs require digestion with exogenous collagenase and the participation of xenogeneic serum, which is not available for human use in China, the United states, japan, and other countries.

In recent years, a Chinese Lufeng doctor team develops a technology for obtaining SVF-gel (stromal vascular fragment cell gel, or adipose tissue stem cell gel) by a pure physical method, and the method adopts a fluid vortex principle to break most mature adipocytes in adipose tissue; meanwhile, the oil drops generated by the broken fat cells are collected and removed by using a flocculation precipitation technology. The utility model adopts physical means without adding any exogenous substance. In the prepared SVF-gel, the adipose-derived stem cells and endothelial progenitor cells are highly concentrated; the concentrated SVF cells remain adhered to the extracellular matrix, and the number of stem cells in the graft material is much greater than that in normal fat. The specific operation of the Lu Peak method is as follows:

1) Centrifuging the obtained granular fat for 3 to 5min at the speed of 800 to 1200g/min, recovering the upper-layer grease for later use after centrifugation, discarding the bottom-layer liquid, and transferring the middle-layer high-density adipose tissue into an injector;

2) The injector filled with the high-density adipose tissues in the previous step is in sealed butt joint with a new injector through an injection port, the piston of the injector containing the adipose tissues is pushed, the adipose tissues are injected into the opposite injector at the speed of 10-20 ml/s, and the injection is continuously carried out for 1-2min;

3) Adding the grease recovered in the step 1) into the adipose tissues injected repeatedly in the previous step, and uniformly mixing;

4) Filtering the adipose tissues obtained in the step 3), filling the filtrate into a sealed injector, pulling off a plug of the injector, keeping the negative pressure in the injector, and then slightly shaking; centrifuging the vibrated mixture for 3 to 5min at 1800 to 2200 g/min;

5) And 4) after the centrifugation, if the mixture is layered, the top layer is grease, the bottom layer is swelling liquid, and the volume of the grease layer accounts for 80% or more of the volume of the whole mixture, taking the intermediate layer product to obtain SVF-gel, and obtaining the transplantation material containing the highly concentrated fat source stem cells and the extracellular matrix.
