This is a randomized controlled multi center study on diabetic patients with the aim of evaluating the efficacy of the adipose tissue processed with the SyntrFuge™ system in diabetic patients with diabetic foot ulcers. In particular, it will be evaluated whether the microsized fat graft will be able to shorten the healing times of these wounds. Patients will be randomized to the treatment group with adipose tissue processed with the SyntrFuge™ system (injection of autologous microsized adipose tissue) or to the control group represented by the standard of care.
