Ma. Aleksandrova et al., The effect of the alien gene GDNF on the development of homo- and xenografts in the rat brain, RUSS J GEN, 36(11), 2000, pp. 1308-1314
A transgenic line of Drosophila melanogaster was selected which carried the
following genes: Delta, lacZ (for bacterial galactosidase), and human GDNF
(for glial cell line-derived neurotrophic factor). Drosophila neuroectoder
mal embryonic cells were transplanted with the embryonic neurohomografts in
to the occipital brain region of an adult rat. Xenografts were found to blo
ck scar formation at the graft-host tissue boundary, stimulated homograft d
evelopment (so that it was twice as large as the control homograft transpla
nted alone with no xenograft added), and noticeably improved vascularizatio
n of the homograft area.
