WebSome of the cells from the placenta develop into an outer layer of membranes (chorion) around the developing blastocyst. Other cells develop into an inner layer of membranes (amnion), which form the amniotic sac. When the sac is formed (by about day 10 to 12), the blastocyst is considered an embryo. Web16 apr. 2024 · The blastocyst implants in the uterine wall when the cells of the trophectoderm nearest to the inner cell mass (ICM) touch and adhere to the uterine lining. On contact, the cells of the trophectoderm begin to divide rapidly, causing it to become several layers thick.
