Abstract
regeneration in the peripheral nervous system. They migrate
into the injury region of spinal cord, which are involved in
remyelination and are regarded as the source of numerous
molecular signals that could potentially support the growth
of axons in the central nervous system. In the present work
we describe the behavior of migrating into the injury dosed
region spinal cord Schwann cells under the influence of
neurotrophic factors - vascular endothelial growth factor
(VEGF) and fibroblast growth factor 2 (FGF2), delivered
by direct introduction of «naked» plasmid DNA and by
transplantation of genetically modified human umbilical cord
blood mononuclear cells.
Using immunohistochemical detection of markers of S100,
GFAP, Krox20 and HSP25 identified different phenotypes
of migrating into the spinal cord of endogenous Schwann
cells. Found that greatest influence on their numbers in the
injury region provides local delivery of genes vegf and fgf2
by human umbilical cord blood mononuclear cells. However,
the direct introduction of the same plasmid may also be
promising in the case of synthetic platforms that enhance
its transfection activity.
