Fig. 3. Increased apoptosis in dic-1(RNAi) embryos. (A) Apoptotic cell corpses (arrowheads) were counted in 380 cell or bean cell stage embryos of wild type N2 strain with or without dic-1 knockdown. This procedure was repeated with ced-3(n717) strain. (B) TUNEL-positive cells in wild-type and dic-1(RNAi) embryos were scored with a fluorescence microscope at the same embryonic stages as in A. Scale bars: 10 µm. Error bars indicate standard errors of the mean (s.e.m.).
