FIG. 7.

Proliferation of EREB2.5 cells constitutively expressing high levels of Notch1IC after estrogen starvation. (A) Ten thousand cells/well of the indicated cells were plated into 96-well plates in growth medium without estrogen. Cell proliferation was monitored by MTT assays as described in Materials and Methods each day over the course of 6 days. (B) Same as for panel A, except that the cells were grown in media containing estrogen. T-bars indicate standard errors.
