Abstract

The present invention provides methods for treating critical limb ischemia (CLI), including increasing wound healing, decreasing wound size, increasing survival-free amputation, preventing amputation, preventing or delaying de novo gangrene, increasing survival probability, and preventing or delaying death, in subjects who prevent a vascular occlusion that cannot be resolved by using a standard method of revascularization, i.e. a subject with “no-option” CLI. Methods of the invention include administering to a subject with no-option CLI an isolated cell composition for tissue repair comprising a mixed population of cells of hematopoietic, mesenchymal and endothelial lineage, wherein the viability of said cells is at least 80% and the composition contains: a) about 5-75% viable CD90⁺ cells with the remaining cells in said composition being CD45⁺; b) less than 2 μg/ml of bovine serum albumin; c) less than 1 μg/ml of a enzymatically active harvest reagent; and d) substantially free of mycoplasma, endotoxin, and microbial contamination.
