(A)TF-1 cells cultured in RPMI-1640, stimulted with 1ng/mL SCF for 72h. (B)Unstimulated TF-1 cells cultured in RPMI-1640 for 72h.
The dose-effect curve of SCF was shown in Figure 2. It was obvious that it significantly promoted cell proliferation of TF-1 cells. The ED50 for this effect is typically 6.07 to 13.69ng/mL.
