¹⁾ Reconstructed complexes and OCGCs were subjected to in vitro growth culture. ²⁾ Reconstructed complexes and OCGCs were subjected to in vitro maturation culture after in vitro growth culture. DOs were cocultured with GCs and early MGCs. ³⁾ Oocytes were collected from the early antral follicles for culture. ⁴⁾ Fully grown oocytes were collected from late antral follicles (4–6 mm). ⁵⁾ FC, filamentous chromatin; SC, stringy chromatin; GV, germinal vesicle I–IV; ED, early diakinesis; LD, late diakinesis; MI, metaphase I; AI-TI, anaphase I and telophase I; MII, metaphase II; DG, degeneration.
