Figure 6. The morphology of hASCs on different NFS: (a) under light microscopy.

Figure 6

Scale bar  = 100 μm; (b) under SEM. Scale bar  = 50 μm. Both in (a) and (b), the hASCs showed round spots because they released from culture flasks by trypsin on day 1 after seeding in NFS. On day 3, the hASCs extend their bodies attaching on the NFS fibers and proliferated in the nanofibrous space. Seen in (a), on day 7, the number of hASCs increased in all 3 NFS. In (b), the hASCs showed like white film in irregular shape attaching on the fibers around and grew in number from day 3 to 7.
