Presentation Transcript

  1. 11.27 Development of a human embryo from fertilization to implantation

  2. 11.28 Comparison of early cleavage in (A) echinoderms and amphibians and (B) mammals

  3. 11.29 Cleavage of a single mouse embryo in vitro

  4. 11.30 Maintaining lineages in the mouse blastocyst The trophoblast cells secrete fluid into the morula to create a blastocoel. As the blastocoel expands, the ICM becomes positioned on one side of the ring of trophoblast cells. The resulting type of blastula is called a blastocyst.

  5. 11.31 Hatching from the zona and implantation of the mammalian blastocyst in the uterus

  6. 11.32 Schematic diagram showing the derivation of tissues in human and rhesus monkey embryos

  7. 11.33 Tissue formation in the human embryo between days 7 and 11 (Part 1)

  8. 11.33 Tissue formation in the human embryo between days 7 and 11 (Part 2)

  9. 11.33 Tissue formation in the human embryo between days 7 and 11 (Part 3)

  10. 11.33 Tissue formation in the human embryo between days 7 and 11 (Part 4)

  11. 11.34 Amnion structure and cell movements during human gastrulation (Part 1)

  12. 11.34 Amnion structure and cell movements during human gastrulation (Part 2)

  13. 11.35 Human embryo and placenta after 50 days of gestation

  14. 11.39 Axis and notochord formation in the mouse (Part 1)

  15. 11.39 Axis and notochord formation in the mouse (Part 2)

  16. 11.39 Axis and notochord formation in the mouse (Part 3)

  17. 11.40 Expression of BMP antagonists in the mammalian node Chordin Noggin

  18. 11.41 Anterior-posterior patterning in the mouse embryo (Part 1) + RA + Nodal Chordin, Noggin, Dkk Nodal BMPs FGFs Wnts

  19. 11.41 Anterior-posterior patterning in the mouse embryo (Part 2)

  20. 11.42 Evolutionary conservation of homeotic gene organization and transcriptional expression in fruit flies and mice

  21. 11.43 Axial skeletons of mice in gene knockout experiments

  22. 11.44 The effect of retinoic acid on mouse embryos (Part 1)

  23. 11.45 Schematic representation of the chick and mouse vertebral pattern along the anterior-posterior axis (Part 1) Vertebrates: 7 cervical, 13 thoracic, 6 lumbar, 4 sacral, and a variable number of caudal vertebrae. Chcicken: 14 cervical, 7 thoracic, 12 or 13 lumbosacral, and 5 coccygeal.

  24. 11.46 First cleavage and axis formation in the developing mouse The hypoblast forms on the side of the inner cell mass that is exposed to the blastocyst fluid. The dorsal axis forms from those ICM cells that are in contact with the throphoblast and amnionic cavity.

  25. 11.47 Left-right asymmetry in the developing human

  26. 11.48 Situs formation in mammals
