| width=500px|height=450px|controller=true|autoplay=false</qt> | Movie shows in vitro development of a human morula to blastocyst between day 3 and day 6 post-fertilization.
00:00 day 3 - Initially a solid mass of cells morula stage enclosed by the zona pellucida. 00:18 day 4 - blastocoel formation 00:22 - inner cell mass (embryoblast) 00:29 - maximal expansion of blastocyst in ZP 00:31 - contraction 00:32 - re-expansion 00:37 day 5 - contraction 00:38 - re-expansion 00:39 - contraction (collapse) 00:40 - re-expansion (blastocoel enlargement) 00:41 - commence blastocyst hatching (1 o'clock position) 00:44 day 6 - complete hatching, blastocyst expansion (inner cell mass 2 o'clock position) 00:47 - trophoblast layer thickens 00:53 - movie finishes
