Figure 3: Reendothelialization of arteries assessed by SEM at 7 ((a), top) and 14 days ((b), top) after stent implantation. SEMs images are the intact stented arterial segments. Bar graphs indicate percentage of re-endothelialized area of total stented area ((a) and (b), bottom). Data represent the mean ± SEM ( ). The scale bar represents 100 μm (top panels) and 20 μm (bottom panels) in (a) and 500 μm in (b). versus BMSs or SESs.
