Animation 1: External surface of the blastocyst Animation 2: Bisected blastocyst rotated about the y-axis. Animation 3:Blastocyst cut in half along a plane perpendicular to that in Animation 2.
Animation 4 : Blastocyst with a segment of the trophoblast removed to show the blastocystic cavity and inner cell mass. Animation 5 : As Animation 2 but rotating about the x-axis. Animation 6 : As Animation 3 but rotating about the x-axis.

In addition to these animations that were made from the WinSurf reconstructions, we are also providing the original WinSurf files together with a WinSurf Viewer. Models displayed in the Viewer can be rotated about all three axes, users can zoom in and out, and models can be translated. Also, the color and opacity of different objects in the models can be varied.
