PGD₂ treatment causes a growth advantage of HEK‐DP2+DP1 and HEK‐DP1 but not of HEK‐DP2 cells. (A) PGD₂ treatment of DP1‐expressing cells led to morphologically visible growth advantage compared to HEK‐DP2 cells. Data show representative images of 4 independent experiments. (B) Cultures of serum‐starved HEK‐DP2+DP1, HEK‐DP1, or HEK‐DP2 cells were treated with increasing concentrations of PGD₂ or 10% FBS and their electrical resistance was monitored for more than 60 h on an ECIS device. Data show means of 5 independent experiments + sem
