VEGFA and ischemia: Thus, 28 days after ischemia modeling (14 days after the moment of gene and gene cell therapy), according to the capillary density criterion, in the calf muscle of the ischemic limb, the expression of this index decreased in the following sequence: UCBC Ad5-Ang → UCBC Ad5-Vegf + Ad5-Ang → Ad5-Vegf + Ad5-Ang → Ad5-Ang → Ad5-Vegf + Ad5-Ang + Ad5-Gdnf → UCBC Ad5-Vegf → Ad5-Vegf → UCBC Ad5-Vegf + Ad5-Ang + Ad5-Gdnf (Figure 4).
