Description
Aborting embryo. Coloured scanning electron micrograph (SEM) of an aborting 6-8 cell human embryo undergoing necrosis (tissue death). The zona pellucida (yellow), the membrane which surrounds the embryo, has been artificially fractured (opened up). It has become thick and compact and has lost its usual striated appearance. The blastomeres inside, the embryo cells formed from divisions of the fertilized egg, are degenerating with fragments seen (green). Magnification: x2,000 at 6x7cm size. x1,700 at 5x7cm size.
