[Effect of nanofat combined with platelet-rich plasma for treatment of pressure injury wounds in rats].

To investigate the effect of allogeneic nanofat combined with platelet-rich plasma (PRP) for treatment of pressure injury wounds in rats. Forty SD rat models with pressure injury wounds were randomly divided into 4 groups ( The combined treatment with nanofat and PRP achieved the highest wound healing rates at all the time points of observation ( Nanofat combined with PRP can significantly promote healing of pressure injury wounds in rats, and their synergistic effect sheds light on a new strategy for treatment of pressure injury wounds.
