We are aware that probably the most relevant limitation of our study will be the lack of gene validation by means of RT-PCR analysis, as a consequence of modest RNA amounts collected right after bioreactor experiments. Nevertheless, our work aimed to determine, initial of all, biological patterns of interest that has to be subsequently Epigenetic Reader Domain reconfirmed. proof that assistance smooth muscle cells hyperplasia and proliferation as the main bring about of in-stent restenosis, modifications in endothelium permeability and raise in cholesterol transport across cells seem to be the endothelial contribution to vascular injury post stent implantation. Our data add new products that need to be validated in human model by searching, as an example, for genetic variations in those genes that we’ve identified.

Conclusions Low shear strain together with stent procedure would be the experimental situations that mostly modulate the highest number of genes in human endothelial model.

We are conscious that the most relevant limitation of our study would be the lack of gene validation by way of RT-PCR analysis, as a consequence of little RNA amounts collected soon after bioreactor experiments.
