Changes of ERK and p-ERK in OEC treated rats. Compare with the sham group and the injury group, OECs graft can lead to a significant increase on the p-ERK expression both on the 14th day and the 21st day while there were no differences on the ERK expression among three groups (A). The quantitative analyses for ERK and p-ERK on the 14th day and the 21st day were showed in B-C. The images indicated that the p-ERK expression increase significantly (*P < 0.05) on the 14th day (B) and the 21st day (C).
