Effects of in utero exposure to genistein (GEN) and DEHP on Sertoli, proliferation, and early germ cell markers. Relative mRNA expression of Sertoli cell markers Wt1 (A) and Abp (B), Sertoli cell and Leydig marker Nestin (C), early germ cell markers Plzf (D), Foxo1 (E), and Sohlh2 (F), and proliferation marker Pcna (G) in PND3 and PND6 testes. Data are expressed as mean relative mRNA levels ± SEM normalized to alpha-tubulin (n = 4 per treatment). Asterisks indicate a significant difference relative to control (p ≤ 0.05); C, Control; G, GEN; D, DEHP; G + D, GEN + DEHP.
