Title:
METHOD OF GENE TRANSFER VIA VASCULAR SYSTEM OR URETER
Document Type and Number:
WIPO Patent Application WO/2002/083185
Kind Code:
A1
Abstract:
It is intended to provide a method of transferring a gene via vascular system or ureter. In a preferred embodiment, an aqueous solution containing an expression vector having a desired gene is injected $i(ex vivo) via the vascular system of a desired organ or ureter and thus the desired gene is transferred into the injected region. This method is particularly useful in an $i(ex vivo) gene therapy wherein hepatocyte growth factor (HGF) gene is transferred into a transplanted kidney by using the electroporation method. By using this method, it is possible to make HGF to continuously exert its effect not on the organs in the whole body but exclusively on the transplanted kidney. Thus, it is a safe and effective therapy of protecting the take of the transplanted kidney.
