Scheme 1

ADSCs delivery scheme in a murine model of hindlimb ischemia. A Intramuscular—ADSCs were injected into the gastrocnemius muscle of the limb where the artery ligation in quadriceps muscle was performed. B Intravenous—ADSCs were injected into tail vein. C Contralateral—ADSCs were injected into the gastrocnemius muscle of contralateral limb, where femoral artery ligation was absent (X-ligation site).
