This image shows a portion of a fruit fly ovary that has been treated with fluorescent probes, which were then imaged using UNLV’s confocal laser-scanning microscope. The dark region in the top left corner is a single-celled oocyte that will soon be fertilized to give rise to a new fly. Nuclei are shown in scarlet (where DNA is stored). An ominous skull-shaped nucleus is visible within the oocyte. The cytoskeleton that acts as a cell’s muscles are shown in grey. Adhesive junctions that hold cells together are shown in blue. This data reveals how cells change shape as they move and grow within a developing tissue.
