CIL (2011) CIL:39043, Drosophila melanogaster, egg, invertebrate nurse cell. CIL. Dataset

This fluorescent micrograph shows the developing egg chambers within the Drosophila melanogaster (fruit fly) ovary. The egg chambers house the maturing eggs - these are the cells at the tips of the egg chambers that face towards the outside of the image. The other cells present are called nurse cells; they occupy the rest of the chamber and assist the developing egg cells as they increase in size over time to produce a mature egg. The specimen has been stained with phalloidin, which marks the actin in the cells green and a nuclear marker that highlights the nuclei in red.

本荧光显微图像展示了果蝇（Drosophila melanogaster）卵巢内发育中的卵室。卵室内容纳着成熟的卵子，这些卵子位于卵室尖端，面向图像外部。其他存在的细胞被称为哺育细胞；它们占据了卵室的大部分空间，并协助发育中的卵细胞随着时间的推移逐渐增大，最终形成成熟的卵子。标本经发状素染色，发状素将细胞中的肌动蛋白标记为绿色，同时使用核标记突显细胞核，呈现红色。
