Fig 2. miR-224 promoted the migration and invasion in cervical cancer cells.

(A) Wound healing assay was implemented in cervical cancer cell line SiHa and CaSki after transfected with 50 nM of miR-224 mimic or negative control (miR-NC). The wound healing was measured at the time points as indicated. Bars represented the average percentage of wound healing ±s.d. ** P<0.01. (B) Cell invasion capabilities were measured in SiHa and CaSki cells with transwell chambers, as described in materials and methods. Photos were representative fields of invasive cells on the membrane with a 200-fold magnification. Bar graphs represented the average number of cells per field on the underside of the membrane ±s.d. ** P<0.01.
