Dose-dependent motility stimulation of CT-26 mouse colon cancer cells by purified B. stearothermophilus PGI. CT-26 cells were plated in culture medium in the absence or various concentrations of PGI. Representative photomicrographs of cells plated in the absence (A) or presence of 10 pg/ml (B) or 100 pg/ml (C) PGI are shown.
