Human Zygote, Morula and Blastocyst (day 1-6)

Human blastocyst development (in vitro) from day 1 to day 6.

• Day 1 - zygote, the first diploid cell.
• Day 2 - 2 then 4 blasomeres, the first cells formed by mitotic cell division.
• Day 3 - morula.
• Day 4 - compacting morula.
• Day 5 - blastocyst.
• Day 6 - hatching blastocyst from zona pellucida shell, after this event the blastocyst can now attach and implant into the uterine wall.
