INTRACEREBRAL or intraspinal grafting of genetically modified primary
fibroblasts has been shown to enhance functional recovery in several m
odels of CNS disease, including spinal cord injury. Most of these stud
ies utilized retrovirus vectors. In this report, we describe in vitro
conditions for genetically modifying primary fibroblasts with recombin
ant adenovirus vectors carrying the lacZ or green fluorescent protein
(GFP) genes. As intraspinal allografts in animals immunosuppressed by
cyclosporin A, the genetically modified cells survived and expressed t
he transgenes for at least 2 months. We conclude that recombinant aden
ovirus vectors are efficient and convenient tools for ex vivo gene the
rapy in the CNS. (C) 1998 Rapid Science Ltd.
