Fig. 2. Cysts of asp^dd4 spermatocytes. The cells are stained to reveal DNA (blue), microtubules (green) and either Centrin (red; A) or -tubulin (red; B). The equivalent monochrome images for the centrosomal antigens and microtubules are shown in the respective central and right hand panels. Although the meiotic spindles look abnormal, their poles appear to be organised in discrete structures. Note the wide range of meiotic stages throughout the same cyst.
