Exogenous SLPI remarkably inhibited the migration and invasion of HPV E6-expressing HNSCC cells. a, b Transwell migration and invasion assay demonstrated that SLPI could inhibit the migrating and invasive abilities of HPV E6 positive and E6 negative HNSCC cells. c, d Wound healing assay revealed the inhibitory role of SLPI in HNSCC cells migration. *P < 0.05. **P < 0.01
