Line Plot from Scientific Research

Gene tracks show a region of chromatin (red box) upstream of mrc1a that is uniquely open in the double-positive CHT EC fraction but not the other three cell populations. Green bars denote the position of the 125 bp enhancer sequence and the 1.3 kb sequence used to generate the reporter transgenes. Image on the right shows transient GFP expression in an F0 embryo injected with the 125 bp enhancer sequence coupled to a minimal promoter and GFP.
