Expression of mRNA for Fcgrt (FcRn) and Prdm1 (Blimp-1) in the SI of developing rats.

Relative mRNA levels of Fcgrt (a, c) and Prdm1 (b, d) in the proximal and distal SI in 7, 14, 21, 28 and 35 days old rats (n = 4–6) during postnatal development (a, b) and in 17 days old rats treated with PHA or protease at 14–16 days of age (n = 3–4) to induce precocious gut maturation, compared to control rats (c, d). (mean ± SD, a–b and * p < 0.05; *** p < 0.001).
