The winning image of this month's Nature Cell Biology and Nature Reviews Molecular Cell Biology 'Cell of the Month' competition was submitted by José Moreira (The Danish Cancer Society, Copenhagen, Denmark (jom@cancer.dk)). It shows a transformed epithelial amnion cell.

Fixed, transformed epithelial amnion cells were immunostained using antibodies against a protein of the 14-3-3 family (14-3-3σ; green) and keratin filaments (red). The image was obtained using a laser-scanning microscope (Zeiss LSM 510). Bar, 20 μm.

The winner would like to acknowledge The Danish Cancer Society for funding this work.
