(A) Transwell migration assay of HSA/c with NGF neutralising antibody. The asterisk indicates significant difference (*P<0.05 the Tukey–Kramer test) vs 0 μg ml−1. (B) Transwell migration assay of HSA/c with K252a (tyrosine kinase inhibitor for TrkA). K252a (100 nM) reduced cell migration significantly as compared with 0 nM. Moreover, 300 nM of K252a reduced cell migration significantly as compared with 0 and 100 nM. The asterisk indicates significant difference (*P<0.05, **P<0.05, the Tukey–Kramer test).
