Peroxidase-positive cells were counted under light microscopy on equivalent surface areas in different tissues of transgenic and nontransgenic embryos. The frequencies were expressed as relative values, 1 being attributed to the nontransgenic samples. In absence of positive cells in the nontransgenic samples, the presence of peroxidase-positive cells was expressed as a +.
AU+ indicates CMV-GMTag AU+ E18 embryos; NT, nontransgenic E18 embryos; Olf epith, olfactory epithelium.
