From: Thyroid hormone transport and metabolism are disturbed in the placental villi of miscarriage
The expression of THRα was downregulated in placental villi of miscarriage but not THRβ. (A) Immunohistochemistry staining for THRα. Sections were counterstained with hematoxylin. Original magnification: 400×. (B) Sections from thyroid tumors were used as positive control. (C) PBS was used instead of primary antibody in the negative control. (D) Rate of THRα-positive cells in placental villi. (E) Immunohistochemistry staining for THRβ. Sections were counterstained with hematoxylin. Original magnification: 400×. (F) Sections from thyroid tumors were used as positive control. (G) PBS was used instead of primary antibody in the negative control. (H) Rate of THRβ-positive cells in placental villi. Data were shown as the mean ± SD (n = 20). *: P < 0.05. ETP: elective terminations of pregnancy
