MSCs are having angiogenic activity and hence may be excellent source to develop neo-vasculature and hence could be explored for their therapeutic potential for treating Critical Limb Ischemia. MSC's also display membrane-bound and insoluble secreted molecules involved with cell attachment to neighbouring cells and to the extra cellular matrix19 Adipose derived Stromal vascular fraction and Mesenchymal Stem Cells has been found in preclinical studies to be safe and effective.
