Figure 4
Growth curve of UB09 cells after transfection of RON. The cells (1 × 104 per well for six wells) were cultured in 10% serum-containing medium with or without doxycycline (1 μg ml−1). The cell number was calculated from 3 to 9 days using a cell counter. Those cells expressing higher RON had a significantly faster growth rate, as indicated by asterisks (P=0.0028, t-test).
