[3-D reconstruction of early preimplantation mouse embryo]

Method of 3-D reconstruction approaches for early mouse embryo in preimplantation stages was modified. The developed technique is based on application of light microscopy of serial thin sections and well known soft operating. The designed method enabled us 1) to get serial sections of a single mouse embryo; 2) to create an orthogonal system independent on the sample for orientation of virtual sections. The adequacy of 3-DR protocol was checked on reconstruction of air bubbles embedded in epoxy resin as a model of sphere.
