Proliferation synergism of SCF with IL-5 in TF-1 cells. Proliferation synergism of SCF with IL-5 in TF-1 cells. Rapid growing TF-1 cells were washed and cultured separately in cytokine-free medium (□), SCF (50 ng/mL, ▪), GM-CSF (2 ng/mL, ○), GM-CSF+SCF (•), IL-5 (5 ng/mL, ▵), or IL-5 + SCF (▴)-containing medium. The viable cell numbers were determined daily by trypan blue staining and are shown as the percentage of the initial viable cell number. Each number represents the average from four independent duplicated experiments. The standard deviations are indicated as error bars. Huei-Mei Huang et al.

Overexpression of IL5R does not increase the mitogenic activity of IL-5. Overexpression of IL5R does not increase the mitogenic activity of IL-5. Rapid growing TF-1, JYTF-1, TF1, and TF8 cells were cultured in IL-5–containing (▧) or cytokine-free (□) media for 24 hours and then 1 × 104 viable cells were subjected to [3H]thymidine pulse-labeling assay as described in Materials and Methods. For each sample, data shown is the average of 13 to 17 independent measurements (n). Huei-Mei Huang et al. Blood 1999;93:2569-2577 ©1999 by American Society of Hematology
