| 11. | These proteins are both synthesized in the neuroblast and segregate into only the GMC during divisions.
|
| 12. | Nerve fibers emerge from these neuroblasts to form the marginal layer ( the white matter ).
|
| 13. | It is also possible that Prospero simply inhibits the proliferation of type II neuroblasts without transforming them.
|
| 14. | Type I neuroblasts that have had the gene encoding for Prospero knocked out leads to tumor formation.
|
| 15. | Neuroblast with slightly more Delta protein on its cell surface will inhibit its neighboring cells from becoming neurons.
|
| 16. | Slow Proliferating Cells ( Type B ) : express GFAP, and function to ensheathe migrating Type A Neuroblasts
|
| 17. | Two proteins play an important role in setting up this asymmetry in the neuroblast, Prospero and Numb.
|
| 18. | Early stages include impaired proliferation and migration of neuroblast, while later stages show disordered post-migration development.
|
| 19. | The neuroblast repeatedly undergoes this asymmetric cell division while the GMC continues on to produce a pair of neurons.
|
| 20. | The mitotic spindle orientation is mediated by Inscuteable, which is segregated to the apical cortex of the neuroblast.
