Clinical Trial I/II Opened, Randomized and Controlled for the Study of the Use of Stem Cells Therapy in Insulinized Diabetic Patients Type 2 With Critical Ischemia in Lower Limbs (CLI): Study of the Needs of Insulin

• Status: Terminated
• Trial end date: 2018-07-01

Summary

To study the effect of the stem cells therapy autologous mononuclear from the bone marrow, autologous progenitor endothelial CD133 cells from the bone marrow and autologous mesenchymal stem cells from adipose tissue on the inflammatory cytokines, the resistance to insulin and the decrease of the needs of insulin, besides evaluates the safety, viability and efficiency of the intra-arterial infusion of stem cells in diabetic patients type 2 with CLI.
