Fig. 3. Time course of GFP expression of in differentiating
Mixl1GFP/w heterozygous and
MixlGFP/GFP null ES cells as determined by flow cytometry.
Both lines initiated GFP expression at day 2.5 and peak expression was seen at
day 4. The frequency of GFP-positive cells diminished more quickly in
Mixl1 heterozygous cells than in those deficient in Mixl1.
The percentage of GFP-positive cells is shown in the lower right of each
plot.
