Figure 3. SFN inhibited migration in U87MG and U373MG cell lines.

Figure 3

Confluent U87MG and U373MG cells were scratched and incubated at different concentrations of SFN (µM). The area covered by migrating cells was recorded by phase-contrast microscopy connected to a digital camera at time 0 and 24 h. The wound closure area was calculated by measuring the diminution of the wound bed surface upon time using Image J software. Representative pictures of three independent experiments were shown. *, indicates P<0.05 versus no SFN group.
