Disappearing cell membranes in a compacting embryo

LM of a stage 2 embryo on day 4 in vitro showing disappearing cell membranes (compaction 5). Nine to ten nuclei and a variable number of nucleoli are visible. This morula did not complete further cell divisions until after compaction was finished and cavitation had begun.
