FIG. 2.

Human CSF promotes the mobility and migration of hAMSCs and hfNPCs. Nanopatterned surfaces were used to quantify the speed and distance of the hAMSCs and hfNPCs after they were cultured in Ctrl, A-CSF, or H-CSF for 14 days. A schematic of the nanopatterned surface, along with electron microscopy images can be seen in (A). (B–D) The hAMSCs cultured in H-CSF displayed a higher speed and longer distance traveled when compared with those cultured in Ctrl and A-CSF conditions. Green tracks represent the migratory paths taken by hAMSCs on the nanopatterned surface. (E–G) The hfNPCs cultured in H-CSF had a significant difference in speed and distance compared with the other groups. Error bars represent SEM. *P<0.05, **P<0.01.
