1. The mitotic spindle function in embryonic neuroblasts and regulation of neurogenesis. 2. Numb ( blue ) is asymmetrically distributed within the neuroblast . 3. Pon binds to Numb and colocalizes with it during neuroblast cell division. 4. Type II neuroblasts do not contain detectable levels of Prospero. 5. Induction of neural tissues causes formation of neural precursor cells, called neuroblasts . 6. Each neuroblast goes on to create a specific sequence of cells with particular identities. 7. Other proteins present in the neuroblast mediate the asymmetric localization of Numb and Prospero. 8. CD24 is a glycoprotein expressed at the surface of most B lymphocytes and differentiating neuroblasts . 9. In all, a neuroblast is capable of generating an indefinite number of neurons or glia. 10. It is expressed in early development in the neuroblast along with ?-internexin and peripherin.
