Objective The present study evaluated the role of stromal vascular fraction(SVF) cells on autologous adipose granule(AG) transplantation.Methods Adipose tissue was harvested in the scapular region of 6 healthy New Zealand white rabbits.Stromal vascular fraction(SVF) cells combined with autologous adipose granule were implanted in the ears of the rabbits as the experiment group.Pure adipose granule was as the control group.The volume of adipose tissue was evaluated 1,3 and 6 months after surgery by B-mode ultrasound and caliper.Both ears of the rabbits were compared histologically 6 months after surgery.Results 1、3、6 months after surgery,the survival rates of the control group were(64.35±8.36)%、(58.22±2.88)%、(50.61±9.47)%;the survival rates of the experiment group were(77.42±5.1)%、(67.95±6.09)%、(72.75±4.37)%.The differences of the two groups were statistical significant(P0.05).6 months after surgery,HE staining of both groups was similar to normal adipose tissue and there was no significant difference between the two groups.Conclusion Autologous stromal vascular fraction(SVF) cells can improve the survival rate of transplanted fat tissue and provide experimental basis for clinical fat transplantation.
