Introduction

Very high power TEM of the cell junction of a stage 2, 4-cell embryo in vitro 44 hours post-insemination (original magnification x69,610) . Desmosome-like junctions are present and the increased electron density within the cell membrane converge toward each other in the intercellular space.

Mt = microtubule
S = smooth endoplasmic reticulum
