Shuffling fat (SF) is obtained by refining macrofat (MF), both of which have been applied in autologous fat grafting. However, few studies have focused on comparison effects of platelet-rich fibrin (PRF) on MF and SF grafting. Grafts were prepared by mixing MF and SF with PRF or normal saline at a ratio of 5:1, and grafted into symmetric recipient sites of a mouse's buttock. Grafts were harvested and analyzed at 4, 8, and 12 weeks. Groups containing PRF showed high volume retention rates and microcosmic evaluation scores at each time point compared with the control groups. Although without improved volume retention rate, group of SF containing PRF showed superior microcosmic evaluations compared with group of MF containing PRF. The results demonstrated that both the efficacy of MF and SF grafting can be enhanced by PRF, with even better quality of grafts for the SF grafting.
