Poloxamer 188 Washing Lipoaspirate Improves Fat Graft Survival: A Comparative Study in Nude Mice

Autologous fat transplantation is limited by the uncertainty of graft retention, impeding its application. Among the current strategies for processing lipoaspirates, high-density fat (HDF) is recommended owing to the enrichment of stem cells and washing before cotton concentration for simplicity of operation. Poloxamer 188 (P188) washing has been shown to repair the membranes of damaged cells. This study aimed to investigate the effect of P188-washing on fat graft survival and identify the best technique for processing lipoaspirates.
