Figure 4.
Fluorescence micrographs showing the migration of dura fibroblasts seeded on fibronectin-coated scaffolds of radially aligned nanofibers for (A) 1 day, (B) 3 days, and (C) 7 days. (D) A higher magnification view of the sample in (C). (E) An illustration showing how to calculate the area of void space. (F) The area of void space as a function of incubation time. * and # indicate p<0.05 for samples compared with Random samples and Random F samples in the same period of incubation time. Random: scaffold of random fibers; Random F: fibronectin-coated scaffold of random fibers; Aligned: scaffold of radially aligned fiber; Aligned F: fibronectin-coated scaffold of radially aligned fibers.
