Implanted blastocyst. Computer-generated image of a blastocyst (outlined in red cells) implanted in the uterine wall 11 days after fertilisation. The outer cells,the trophoblasts,are directly involved in the process of implantation. The inner cells are undergoing differentiation into two layers called the epiblast and hypoblast,which together constitute the bilaminar embryonic disc. The pale area at upper centre is the amniotic cavity. This blastocyst measures 0.2 millimetres across | |
