Stunning Science

UNLV life sciences teacher Laurel Raftery and her previous post-doctoral researcher Xiaodong Wu captured this image, magnified 40x with a confocal microscopic lense. It is a portion of a fruit fly ovary that reveals establishing roots that will each make a fruitfly egg. The blue color spots DNA; the huge round blue blobs are nuclei of cells that are making RNA and protein to transfer to the egg, which is primarily unstained. The green and blue areas are the cells that will make the eggshell. There are gaps in the green (blue and red cells) that are mutant cells, which are missing out on a protein called BunA, which controls gene expression; the cells that are missing BunA are disordered and have actually invaded into the location that contains the establishing egg. Raftery’s group’s data recommends that BunA is associated with keeping cells from ending up being intrusive cancer cells.
