Figure 5

Gross and scanning electron microscope images of the artificial vessel; (a) longitudinal view, (b) transectional view, (c) SEM image of the inner surface, and (d) SEM image of the outer surface. The white arrow indicates the polycaprolactone layer, and the yellow arrow indicates the dried sodium alginate hydrogel layer due to SEM sampling. The white asterisk indicates the inner side surface woven in a cross-striped form, and the yellow asterisk indicates the outer surface woven in a helical form. The scale bar indicates 200 μm.
