Angiotensinogen mRNA sequences were detected in all fetal liver samples and appeared to increase 3-fold from 60 to 138 d gestation and then to decrease after birth. In an effort to determine if this phenomenon is specific to the rat or applicable to other species, we compared the ontogenic Received January 18, 1990 ; accepted April 16, 1990 changes in hepatic and renal angiotensinogen gene expression during the last trimester of gestation in fetal sheep. Northern blot analysis of liver and kidney RNA from fetal sheep (1 18 and 138 d gestational age) 1 and newborn lamb are shown in Figure 3 . ./cache/cord-004656-n4h295e5.txt ./txt/cord-004656-n4h295e5.txt
