Figure 3.  FGF and activin activate expression of a reporter gene construct containing 2.1 kb of Xbra2 5′-flanking sequence. Sequences upstream of −381 in the Xbra25′-flanking sequence are dispensable for response of Xbra2to FGF (25 ng/ml) and activin. Embryos were injected with the indicated constructs and reference plasmid and, in some cases, with 1 pg of activin mRNA, as described in Materials and Methods. Normalized firefly luciferase activity from stage 12.5 caps is expressed as fold activation over untreated caps. (n) Number of experiments. Image published in: Latinkić BV et al.
