Effects of ▵STAT5 expression on growth of Ba/F3p210 cells.

Ba/F3p210ΔSTAT5 cells were maintained in either the presence or absence of doxycycline (1 μg/mL), and daily cell counts were obtained. Cell counts from cells maintained in the presence of doxycycline are expressed as a percentage of the cell counts obtained from cells maintained in the absence of doxycycline. Expression of ΔSTAT5 significantly inhibited cell growth; however, the cells were still growing although at a slower rate. No significant effect of doxycycline was observed in Ba/F3p210Ctrl cells.
