Photos of fertilized egg cell and blastocyst

A while ago, I promised photographs to go along with the survey on stem cells conducted recently and reported here. Unfortunately, although I recieved copies of the photos used for the survey, I did not receive permission to use them here. I also found that other photos available on the web are either too old (ie, beyond 5-7 days) or permission to use them is explicitly denied. I have assembled some photos released as part of the President's Council Statement on the Bioethics of Stem Cell Research and attached them to this message. For a fuller discussion of very early embryonic development, I suggest the following website: The photos available at that website cannot be copied. Marie Godfrey, PhD
