Visualization of dynamic developmental processes. (a-e) Series of five embryos stained with a probe (bgm) highlighting the fat-body primordium and revealing dynamic aspects of segmental fat-body specification. Ventral view with anterior to the left. (f-j) Series of five embryos stained with a probe (CG4829) visualizing the lamellocyte precursors. The staining reveals the spreading pattern of lamellocytes across the embryo and the 'hitchhiking' of migrating cells on the retracting germ band.
