Fig. 3

Bmal1 and Per2 transcripts do not oscillate in embryonic tissues. Twenty-four-hour expression profiles of Per2 and Bmal1 mRNA in embryonic (E18-E19) and adult mouse heart, as determined by qPCR. Identical results were seen in the liver and kidney, while the skeletal muscle was not analyzed in this study. Note that the embryonic heart shows little circadian variation in Per2 and Bmal1 expression, in contrast with the robust changes seen in the adult tissue (modified from [39])
