Active | Fruit fly nurse cells transporting their contents during egg development6754| In many animals, the egg cell develops alongside sister cells. These sister cells are called nurse cells in the fruit fly (Drosophila melanogaster), and their job is to “nurse” an immature egg cell, or oocyte. Toward the end of oocyte development, the nurse cells transfer all their contents into the oocyte in a process called nurse cell dumping. This video captures this transfer, showing significant shape changes on the part of the nurse cells (blue), which are powered by wavelike activity of the protein myosin (red). Researchers created the video using a confocal laser scanning microscope.

Hi Abbey,
Thanks for the reminder. Attached is permission, title, and caption for one of the images and a movie from our work funded by NIGMS. The image/movie files are linked below. Let me know if these don’t work for you and I can download and share in a Dropbox folder. Also, let me know if you need more info.
Best,
Adam

Title: Myosin activity drives dynamic cell deformations during oogenesis
Caption: Across many animals, the egg cell develops alongside other sister cells. In the fruit fly, Drosophila melanogaster, these sister cells are called nurse cells, and their job is to ‘nurse’ the developing oocyte. Towards the end of oogenesis, the nurse cells transfer all their contents into the oocyte in a process called ‘nurse cell dumping’ to prepare the oocyte for fertilization; this process involves significant shape deformations on part of the nurse cells (cyan), which are powered by wave-like myosin activity (red). This image shows the cluster of nurse cells amidst transport: Note the unusual cell body shapes and cortical myosin activity!
