We also assessed the cell adhesion, migration and proliferation by staining the device with May-Grunwald stain. From the fig.2a-c, it can be seen that the cell attachment is good on the uncoated stent and there was an increase in cell density after 72h as compared to 24h, which indicates that cells proliferate rapidly on the device.
Leukocyte adhesion assessed after staining the devices with May-grunwald stain correlates well with the above results in that the cells were far less on both polymer coated and drug coated stents as compared to uncoated stent, that is seen in fig.3a-c.
