Brd2a knockdown has opposite effects on cell death at start and end of segmentation. Embryos were analyzed for apoptotic nuclei using TUNEL followed by laser-scanning confocal microscopy and quantified using SimplePCI computer analysis software. A total of 24 embryos and three clutches per treatment (uninjected WT, 8 ng brd2aMO1-injected, and 8 ng control MOc-injected) were assessed. Light micrographs with accompanying dark field maximum projection composite images show representative wildtype (A,B), brd2aMO1-injected (C,D), and control MOc-injected (E,F) embryos at bud stage; and wildtype (G,H), brd2aMO1-injected (I,J), and control MOc-injected (K,L) embryos at prim 5 stage. Cell death appears relatively reduced in morphants at bud stage (D vs. B and F), but increases dramatically compared to controls at prim 5 (J vs. H and L). |
