Anatomy of a Banana Lover

Nicole Evans, Graduate Student (Barolo Laboratory), Department of Cell and Developmental Biology, University of Michigan Medical School

We use the fruit fly, Drosophila melanogaster, as a model system to study how gene expression is controlled during development. This is an image of the inside of a fruit fly larva. The nervous system is shown in blue, with nerves connecting to various parts of the body. The large orange and pink dots are located in the fly's extraordinarily large salivary glands, while the fainter pink structure is the fly's gut. The DNA within each cell nucleus is stained orange with a fluorescent dye. This is a transgenic larva carrying the jellyfish green fluorescent protein (GFP); cells that express the GFP transgene have (pseudocolored) pink nuclei.
