FIG. 2.

RT-PCR for GIP ligand showed that mRNA expression of GIP was present as early as E9.5 and continued through later gestational stages and into postnatal stages (A). Semiquantitative RT-PCR showed increasing GIP expression after E9.5 (C). B: RT-PCR of GIPR (GIP Rec) showed that there was consistent expression of GIPR in early and late developmental and postnatal stages. D: Semiquantitative RT-PCR expression pattern for GIPR showed low relative values at days 9–13, followed by a progressive increase in expression over increasing gestational age. Error bars represent SEM.
