Developmental expression of Staufen-1, Y14, Mago-m, and Pumilio-1 in mouse small intestine using RT-PCR analysis. Fetal, 15 days (Lane 1); fetal, 16.5 days (Lane 2); fetal, 17 days (Lanes 3–5); and newborn (Lanes 6–8). Intestinal segments: proximal (Lanes 3 and 6), middle (Lanes 4 and 7), and distal (Lanes 5 and 8). This is a representative of n = 3 identical experiments.
