Figure 1

Morphological characterization and orcein staining of porcine oocytes during IVM. ( A) Oocyte released from a follicle containing an intact germinal vesicle (GV). (B) The M II stage and extrusion of the first polar body (I PB). Morphological characterization of the porcine oocytes in each stage (a, b, d, and e), and morphological evaluation of each of these stages using orcein staining (c, f). (C) Changes in the nuclear status of oocytes cultured in TCM-199 medium throughout the process of IVM. The oocytes were examined at four different stages of maturation: germinal vesicle (GV), chromosome condense (CC), metaphase I (M I) and metaphase II (M II).
