Embryo Expressing Moesin-GFP (IMAGE) Center for Genomic Regulation Caption Transverse imaging of an embryo expressing Moesin-GFP shows the changes in shape of the contractile amnioserosa tissue during dorsal closure. The arrows indicate the border of the amnioserosa tissue and the edge of the epidermis. While closure proceeds the cells do not thicken but instead decrease in volume. The bar shows 10 microns. The images are individual time-points from a time-lapse of approximately 100 minutes. Credit Laure Saias and Jim Swoger , CRG.
