Flowchart of the experimental timeline and macroscopic observation of tissue after expansion. a The tissue expander is implanted subcutaneously and treated with cell-free fat extract (CEFFE) on day 0. From days 1 to 29, 5 mL of physiological saline was injected into the expander every other day for a total of 4 weeks. Then, the skin tissue was sampled and observed. b Macroscopic observation of the expanded tissue. Necrosis is present in the control tissue. c Retraction rate assessment of expanded tissue. A lower retraction rate is observed in the CEFFE-treated tissue. Data are expressed as means ± SD. p < 0.05
