Figure 4From: PC-3 prostate carcinoma cells release signal substances that influence the migratory activity of cells in the tumor's microenvironmentMigratory activity of neutrophil granulocytes and CTLs in response to cell culture supernatant of either normoxic or hypoxic PC-3 cells. The left graphs show the time-course of the migratory activity. The right graphs show the corresponding time-average and the standard deviation of three independent experiments with cells from different donors (90 cells have been analyzed per sample). Asterisks indicate statistically significant changes.Back to article page
