Adeno-associated virus (AAV) vector having hybrid HGF gene introduced thereto

An adeno-associated virus (AAV) vector, comprising a foreign nucleic acid sequence consisting of:

• (a) the nucleotide sequence set forth in SEQ ID NO:
• 5;
• or
• (b) a codon-modified nucleotide sequence having homology of at least 80% to the nucleotide sequence set forth in SEQ ID NO:
• 5, wherein said codon-modified nucleotide sequence encodes the same amino acid sequence as the coding region of the nucleotide sequence set forth in SEQ ID NO:
• 5.
