Fig. 3. Template activities of the various gata1 constructs. Values in the left column show the percentages of embryos that contained more than 21 GFP-positive cells in the ICM at 22 hours after injection of indicated reporter constructs. Values in the right column indicates that the percentages of embryos that contained more than six GFP-positive cells in the ICM. The numbers of embryos examined for each construct are indicated in the parentheses. dGATA and CACCC denote the double GATA motif and CACCC box, respectively.
