The combined effect of PGE2 (100 ng/ml) and a high dose of LTB4 (10 nM) on human patellar tendon fibroblasts. The addition of PGE2 decreased cell proliferation and the addition of LTB4 at 10 nM did not change the cell proliferation compared to that of untreated cells. When both agents were added in combination, cell proliferation further decreased compared to the already reduced level of cell proliferation brought by PGE2 alone. Two independent experiments were done, with a total sample size of 6 for each group.
