From: Thyroid hormone transport and metabolism are disturbed in the placental villi of miscarriage
Cell proliferation was inhibited and apoptosis was increased in placental villi of miscarriage. (A) Immunohistochemistry for Ki67 was performed to evaluate cell proliferation in villi. Original magnification: 400×. (B) Placental villi sections were stained with TUNEL assay to assess cell apoptosis. Original magnification: 400×. (C) Rate of Ki67-positive cells. (D) Rate of apoptosis cell. Data were presented as the means ± SD (n = 20). **: P < 0.01. ETP: elective terminations of pregnancy. STB: syncytiotrophoblast. CTB: cytotrophoblast. CCC: cytotrophoblast cell columns
