β-carotene in the placentas and embryos of Ldlr+/− and Ldlr−/− pregnant mice administered β-carotene.
| Maternal Genotype and Treatment | Placental/Embryonic Genotype | n | Placental BC (ng/g) | Embryonic BC (ng/g) |
|---|---|---|---|---|
| Ldlr+/− + Veh | Ldlr+/− | 8 | n.d. | n.d. |
| Ldlr−/− | 6 | n.d. | n.d. | |
| Ldlr+/− + BC | Ldlr+/− | 13 | 581 ± 147 | 13 ± 5 |
| Ldlr−/− | 13 | 590 ± 158 | 18 ± 8 | |
| Ldlr−/− + Veh | Ldlr+/− | 10 | n.d. | n.d. |
| Ldlr−/− | 10 | n.d. | n.d. | |
| Ldlr−/− + BC | Ldlr+/− | 6 | 558 ± 187 | 19 ± 10 |
| Ldlr−/− | 6 | 529 ± 99 | 19 ± 10 |
Data are mean ± SD; n = 1–5 placentas or embryos/dam (3–4 dams/genotype); statistical analysis by ANOVA. BC, β-carotene; Veh, vehicle.
