(C) DEF displaying an impaired differentiation of stromal cells into decidual cells. (D) DEF-D400 illustrating alternating decidual cells and impaired differentiated stromal cells (arrows) into decidual cells. (E) DEF-D4000 and (F) DEF-D10000 revealing an obvious differentiation of stromal cells into different sized rounded decidual cells. Scale bar: 20 μm.
