Figure 11. Oocyte and parthenote development in vitro. (A) The oocyte development in OSC culture is accompanied by a satellite (black arrow) and neuronal (white arrow) cells. White arrowhead indicates neuronal extension. (B) DAPI staining of (A). (C) The parthenote shows a blastocoele (white arrow) and inner cell mass (black arrow). (D) DAPI staining of (C). Four cell embryo. (E - G) and morula (H and I). J and K panels show a blastocyst consisting of blastocoele (bc), trophectoderm (te), and inner cell mass (icm) releasing ESC (esc). Left insert in panel K shows enhanced DAPI staining of dividing ESC vs. low DAPI staining of other cells in the culture (right insert). Details in text. Adapted in part from Ref.
