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 [[Cell Division - Mitosis|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 [[Implantation|attach and implant]] into the uterine wall. | |||

Human Blastocyst (day 3 to 6)Movie shows in vitro development of a human morula stage to blastocyst stage. The movie covers the period of the first week (day 3 and day 6) post-fertilization and finishes with the blastocyst "hatching out" of the protective zone pellucida, ready to begin implantation in the second week.
00:18 day 4 - blastocoel formation, now blastocyst stage. 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 |
