Tumor cell proliferative response to IL4 and IL13 stimulation. Glioma cells (A) and RCC (B) were cultured with or without IL4 (20 ng/ml), IL13 (20 ng/ml), or IL2 (20 ng/ml) for 3 days, as described in “Materials and Methods.” The proliferative response was measured by following (3H)-thymidine uptake during the last 12 hours of culture. Results are expressed in counts per minute (cpm) (mean of triplicates ± sd). Data are representative of five independent experiments.
