ABSTRACT
Methods: Two groups of fats were obtained from the left and right sides of a female patient during the abdomen liposuction surgery, respectively. And the fats in experimental group and control group were harvested by the new front opening liposuction cannula and the side hole liposuction cannula, respectively. The differences of adipocyte activity in vitro between 2 groups were compared by observation under the electron scanning microscopy and the glucose transportation test. Then, the fats in 2 groups ( n=20) were injected subcutaneously into the back of 20 nude mice (400 mg fats per injection zone). The differences of the injection area reactions, remaining weight, histological characteristics, and microvessel density (MVD) between 2 groups were compared after 4 weeks and 12 weeks.
