NGF plus TRAIL abrogates the tumourigenic activity of TrkA SH-SY5Y cells in vitro. (a) Representative photograph and (b) histogram demonstrating significant inhibition of TrkA SH-SY5Y but not NT SH-SY5Y or pcDNA SH-SY5Y tumourigenic activity in vitro by NGF (100 ng) alone or in combination with TRAIL (200 ng). Results are displayed as the mean (±S.D.) number of tumours in 10×10 magnification fields in triplicate experiments each performed in duplicate (*statistical significance). (c) Representative phase contrast micrographs demonstrating tumour spheroid appearance of TrkA SH-SY5Y cells in vitro in the absence (control) or presence of NGF (100 ng/ml), TRAIL (200 ng/ml) plus NGF (100 ng/ml) or TRAIL (200 ng/ml) alone.
