Figure 2

(A, B) Fluorescence micrographs comparing the migration of cells when dura tissues were cultured on scaffolds of radially aligned and random nanofibers, respectively, for 4 days. The dashed circle line indicates the border of dura cells after seeding at day 0. (C, D) Magnified views of the center portion shown in (A) and (B), respectively. The arrow marks the center of the scaffold. In (A), the non-uniformity in cell distribution was probably caused by the slight difference in nanofiber density.
