A PHARMACEUTICAL COMPOSITION FOR STIMULATION OF ANGIOGENESIS

Provided is a pharmaceutical composition for growth induction in blood vessel tissue which contains purified plasmid DNA encoding a vascular endothelial growth factor (VEGF) and pharmaceutically acceptable excipients that include a cryoprotectant as a vehicle and/or a pH stabilizer for stabilizing the pH in the range of 7.0 to 9.0, in effective quantities. Also provided is a storage method of plasmid DNA which encodes a VEGF comprising mixing the purified plasmid DNA with a solution of at least one cryoprotectant having properties of a vehicle and/or a pH stabilizer in the pH range of 7.0-9.0. The solution is lyophilized and stored at +2 to +8° C. Supercoiled DNA pCMV-VEGF165 may be used which is produced by culturing Esherichia coli strain TOP10/pCMV-VEGF165. The pharmaceutical composition is administered to a human in quantities sufficient to provide a necessary therapeutic effect. The provided pharmaceutical composition of plasmid DNA pCMV-VEGF165 does not change significantly properties of the active substance when stored for a long time at a temperature from +2 to +8° C.
