Effect of PMA on the migration of ADSCs. After ADSCs reached approximately 70% confluence, wounds were created using a yellow pipette tip. The cells were cultured with or without PMA (100 nM) for up to 24 h and the images were taken at 4 and 24 h after the wounds were created. Scale bar = 200 μm. White dotted line shows the migrating edge
