Fig. 3. Electron micrographs reveal morphological features typical of apoptotic cells. Embryos received 40 Gy of radiation at St. 1, and were fixed within 2 h of the time of death, at a time equivalent to St.100.5 in control embryos. (A) Nucleus of control embryo showing dispersed chromatin; scale bar 2 mm. (B) Nucleus of irradiated embryo, masses of compacted chromatin are apparent (black arrow), and the nuclear membrane is clearly intact (arrowhead); scale bar 1mm. The cell membrane is visible in the top right and bottom left corners of the picture. (C) Nucleus of irradiated embryo displays condensed chromatin which abuts the inner surface of the nuclear membrane (arrowhead); scale bar 1 mm. (D) Nucleus of irradiated embryo which has fragmented into three pieces. Mitochondria are readily identifiable (arrowhead); scale bar 1 mm. The large black globules seen throughout the sections are the electron dense yolk platelets. Image published in: Hensey C and Gautier J (1997) Copyright © 1997.
