From: In vitro analysis of the invasive phenotype of SUM 149, an inflammatory breast cancer cell line
Haptotaxis of human breast cancer cells to extracellular matrix proteins. SUM 149 and SUM 102 cells (105) were placed into the top chamber of a Costar well coated with laminin (50 μg/ml) or collagen I (10 μg/ml) and allowed to invade for 24 hours. Invasive cells were stained with propidium iodide and quantified in 10 random microscopic fields. Micrographs were taken at 200× magnification. Data are expressed as mean ± SEM of at least three independent experiments.
