Fig. 1

H&E staining of decidua tissues in control (A) and treatment A group (B). Scale bar: 300 µm. In figure A, decidual cells (Black arrows), granulosa cells (Blue arrows), dense reticular fibers (Red arrow) and epithelial cells (green arrow). In figure B, decidual cells (Black arrows), degenerated sheet of decidual cells (Red arrow), granulosa cells (Green arrow). C Quantification of the cytoplasm diameter of decidual cells in different grousp. D Quantification of the number of granulosa cells in different group. Data in C and D are summary of ten different slides from 5 different samples. One-way ANOVA, * < 0.01, **P < 0.01
