Table 1 Litter size, feto-placental growth and placental protein measurements.

From: Estrogen receptors alpha and beta in rat placenta: detection by RT-PCR, real time PCR and Western blotting

  1. Values are mean ± S.E.M. for four different dams. A significant increase (p < 0.001) in placental and fetal body weights during gestation and a significant decrease (p < 0.001) in litter number between 16 and 21 dg was detected. Placental protein concentration was measured using the Bradford method; a significant increase in protein content was observed between 16 and 19 dg and 16 and 21 dg (*p < 0.001; LSD test).
