image: Visualization of chromatin structure in the nucleus of cancer cells using Hoechst stain that binds to genomic DNA in the cell nucleus. The cell in the center of the image is in the late prophase stage of mitosis where the chromatids have fully condensed but have not yet begun to pull apart into two daughter cells. Several interphase cells not in the process of dividing can also be seen. This image relates to an article that appeared in the Aug. 19, 2011, issue of Science, published by AAAS. The study, by Dr. D.A. Solomon of the Georgetown University School of Medicine in Washington, D.C., and colleagues was titled, "Mutational Inactivation of STAG2 Causes Aneuploidy in Human Cancer." view more
