Abstract
The extent to which trophectoderm (TE) and inner cell mass (ICM) lineages in the mouse blastocyst remain distinct during the period from the commencement of cavitation up until 48 h later in culture was investigated. Fluorescent latex microparticles were used to label exclusively all TE cells in nascent blastocysts and the position of labelled progeny in cultured blastocysts was examined by disaggregation, by serial sectioning and by whole-mount analyses. The results indicate that, in most blastocysts (80–90%), TE and ICM lineages are entirely separate during this period while in the remainder lineage crossing is limited usually to only one or two cells of either tissue.
