Across
  1. 2. the location where peripheral neurons originate during development
  2. 3. otherwise known as motor neurons
  3. 4. the ability to become any cell in the body, including extra-embryonic tissues
  4. 7. the stage of embryonic development where gene transcription begins
  5. 11. when mesoderm cells are folded into the interior of the blastula
  6. 12. when two layers of cells move towards each other
  7. 13. neurons in flies that were studied to determine molecular mechanisms of axon growth cone movement
  8. 16. neurons otherwise known as sensory neurons
  9. 17. a diffusable factor that repels an axonal growth cone to guide movement
  10. 18. tumors consisting of most tissue types that are formed by implanting an embryo into an adult mouse
  11. 19. packets of cells that are the precursors to muscle cells
  12. 21. the fusion of two embryos; can be proof of totipotency
  13. 22. a survival factor required for neurons to establish connections at their targets; neurons compete for it and those that do not obtain enough lose connections
Down
  1. 1. otherwise known as interneurons
  2. 5. the process by which embryonic tissue movements form the spinal cord
  3. 6. the localized factor that determines the vegetal pole in the embryo
  4. 8. a factor produced by lung buds that inhibits the production of FGF10 in nearby mesenchymal cells, leading to branching; involved with genesis of neurons
  5. 9. neuron precursors that reside on the inner surface of the neural tube
  6. 10. location of embryonic stem cells; each cell is pluripotent
  7. 14. a tissue movement where a layer of cells elongates
  8. 15. a tyrosine kinase receptor for NGF
  9. 20. a diffusable factor that attracts an axonal growth cone to guide movement
  10. 23. a factor produced by lung mesenchymal cells that guides the growth of lung buds
