Mesenchymal Stem Cells in Critical Limb Ischemia
A Randomized, Double Blind, Multicentric, Placebo Controlled, Single Dose, Phase - i/ii Study Assessing the Safety and Efficacy of Intramuscular ex Vivo Cultured Adult Allogenic Mesenchymal Stem Cells in Patients With Critical Limb Ischemia (Cli)
This clinical trial aims to study the safety and efficacy of adult mesenchymal stem cells in critical limb ischemia.
