tiar−/− ES cell proliferation defect. tiar−/− ES (solid lines) and control tiar+/+ or tiar+/− ES (dashed lines) cell lines were grown in media containing methylcellulose in the absence (A) or presence (B) of exogenous LIF. Cell growth was determined by using [3H]thymidine incorporation at the indicated times. Values represent mean values of triplicate samples with vertical bars indicating the SDs. Data are shown for two independent tiar−/− ES cell lines and control tiar+/+ and tiar+/− cell lines. Similar results were obtained in four additional experiments.
