Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Skin graft is a commonly used method in wound repair. The long-term outcome of skin graft is unsatisfied because of the complications of contraction, pigmentation and stiffness. In our preclinical researches, we found that adipose stem cell can improve the texture of grafted skin and reduce contraction. In this trial, we will evaluate the efficiency and safety of autologous adipose stem cells in improving skin graft outcomes.

Stem cell group

Group Type EXPERIMENTAL

autologous adipose stem cell injection

Intervention Type PROCEDURE

Abdominal or buttock fat will be aspirated under local anesthesia or general anesthesia by conventional methods (0.5 ml fat was aspirated per 1 cm2 of skin graft area). The matrix component rich in adipose stem cells will be obtained by chopping, washing and centrifugation. The intervention treatment will be performed after the skin graft sutured. The stem cell components will be injected underneath the skin graft (0.05 ml/cm2).

Control

Group Type PLACEBO_COMPARATOR

saline injection

Intervention Type PROCEDURE

saline will be injected underneath skin graft (0.05 ml/cm2).
