Fig. 2. Protein expression in blastomeres post-compaction. Average number of
blastomeres that were positive for Oct4 (light blue), Cdx2 (pink) and Nanog
(green) in relation to the total cell number (black) and the number of the
inside population (dark blue) as a function of time after compaction. As a
reference, the average number of blastomeres of in vivo developed embryos is
provided (crosses) at 10, 30 and 55 hp-c. Error bars indicate s.d.
