Abstract:
Human mesenchymal stem cells (hMSC) are due to their high differentiation potential, the high proliferation rate and ease of use in the interests of current stem cell research. In order to verify their homing in tissue hMSC are labeled with various substances such as iron oxide nanoparticles. The aim of this study was to show the influence to colony formation and migration ability of hMSC after labeling with iron oxide nanoparticles alone and in combination with a transfection agent (TA).
METHODS
Were examined viabilities ,total iron upload, colony formation assay and migration assays after labeling at 2 and 4 cell passages.
RESULT
There was a significant decrease in colony-forming ability after labeling with iron oxide nanoparticles alone as well as in combination with TA. During migration ability this reducing effect was not statistically significant.
SUMMARY
The data show a statistically significant influence on the labeling with iron oxide nanoparticles alone and with TA on the colony forming ability and migration ability of hMSC, so that labeling of hMSC is critical in terms of their therapeutic efficacy.
