Blastocyst folding
WebJan 1, 2016 · The redox status could be defined as the balance between oxidants (or pro-oxidants) and antioxidants (Fig. 1 ). Oxidants, including free radicals and other reactive species, are continuously produced in the cell. As it is impossible to completely prevent oxidant production, several antioxidant systems have evolved in the cell. The blastocyst is a structure formed in the early embryonic development of mammals. It possesses an inner cell mass (ICM) also known as the embryoblast which subsequently forms the embryo, and an outer layer of trophoblast cells called the trophectoderm. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoel. In the late blastocyst the trophectoderm i…
