Human Conceptus (day 5)

  • By day 5 the blastocyst has a large blastocoel (fluid-filled space) with a single layer of thin (squamous) cells forming the trophectoderm.
  • The inner cell mass can be seen to the left of the blastocoel.
  • The blastocyst is still contained inside the zona pellucida.
