Summary: | Mesenchymal stem cells (MSCs) hold tremendous potential for therapeutic use
in stem cell-based gene therapy. Ex vivo genetic modification of MSCs with beneficial
genes of interest is a prerequisite for successful use of stem cell-based therapeutic
applications. However, genetic manipulation of MSCs is challenging because they are
resistant to commonly used methods to introduce exogenous DNA or RNA. Herein we
compared the effectiveness of several techniques (classic calcium phosphate precipitation,
cationic polymer, and standard electroporation) with that of microporation technology
to introduce the plasmid encoding for angiopoietin-1 (ANGPT-1) and enhanced green
fluorescent protein (eGFP) into human adipose-derived MSCs (hAD-MSCs). The
microporation technique had a higher transfection efficiency, with up to 50% of the viable
hAD-MSCs being transfected, compared to the other transfection techniques, for which
less than 1% of cells were positive for eGFP expression following transfection.
The capability of cells to proliferate and differentiate into three major lineages
(chondrocytes, adipocytes, and osteocytes) was found to be independent of the technique
used for transfection. These results show that the microporation technique is superior to the
others in terms of its ability to transfect hAD-MSCs without affecting their proliferation
and differentiation capabilities. Therefore, this study provides a foundation for the selection of techniques when using ex vivo gene manipulation for cell-based gene therapy
with MSCs as the vehicle for gene delivery. |
