Caption

This image shows human embryonic stem cells grown on a synthetic surface developed by MIT researchers. The cells at top (blue) are stained to reveal their nuclei, while the cells in the middle and bottom are stained for proteins that are known to be present when cells are pluripotent. Green cells are stained for Oct4 (using green fluorescent protein) and red cells are stained for SSEA-4.
