Abstract (original English)
To study the effect of platelet-rich plasma (PRP) on the survival and quality of fat grafts in the nude mice so as to provide a method and the experimental basis for clinical practice. Fat tissue was harvested from the lateral thigh of a 25-year-old healthy woman and the fat was purified by using saline. The venous blood was taken from the same donor. PRP was prepared by centrifugation (200 x g for 10 minutes twice) and activated by 10% calcium chloride (10 : 1). Then 24 female nude mice [weighing (20 +/- 3) g, 5-week-old] were allocated randomly to the experimental group and the control group (12 mice per group). Each subcutaneous layer of two sides of the back (experimental group) was infiltrated with 0.8 mL fat tissue-activated PRP mixtures (10 : 2); the control group was infiltrated with 0.8 mL fat tissue-saline mixtures (10 : 2); 0.14 mL activated PRP and 0.14 mL saline were injected into the experimental group and the control group respectively at 5 and 10 days after the first operation. At 15, 30, 90, and 180 days after the first operation, the samples were harvested for gross and histological observations. All nude mice survived to the end of the experiment. No inflammation and abscess formation of the graft were observed. Experimental group was better than control group in angiogenesis, liquefaction, and necrosis. The grafted fat weight and volume in the experimental g
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • This is preclinical work; animal or laboratory results cannot be applied to humans.
