TAMs enhance the cancer cells migration and invasion in vitro. a The HN4-M, HN6-M and SCC9-M cells could grow to confluency easier than the control cells after 24 h. b The cells invading the filters coated with the Matrigel. The photographs were taken at 100x magnification. (c) The quantification of the cell invasion in five randomly chosen fields. The data were reported as mean ± SD. *** P < 0.001
