Analysis of the ability of various EGF-like
ligands to mediate mitogenesis in 32D.E4 and 32D.E2/E4 cells.
Dose-response analysis of [3H]thymidine incorporation
induced by EGF, NRG1-β, BTC, TGF-α, HB-EGF, or AR in 32D.E4 cells
(░⃞) or 32D.E2/E4 cells (▪) are shown. Data
points are the mean of triplicate samples and are expressed as amount
[3H]thymidine incorporation in cpm.
