Day 2 to 6

As shown in the preceding time-lapse movie, embryos are followed in their development in greater detail. In this case a picture was taken with shorter time intervals creating a slower movie with longer duration. Embryos at the four cell stage (day 2) are cultured until day 6 showing the development of two blastocysts with one of them undergoing spontaneous hatching.
