But neuroblast growth can sometimes spin out of control and become a brain tumor.    From Wordnik.com.  [PhysOrg.com - latest science and technology news stories] Reference

Here, they found that neuroblast cells in the abdomen stopped dividing before reaching the stage that would create Ap clusters.    From Wordnik.com.  [PLoS Biology: New Articles] Reference

Ap cluster neurons form at the end of a long series of neuroblast cell divisions and only in the presence of specific molecular signals.    From Wordnik.com.  [PLoS Biology: New Articles] Reference

In the fruit fly's developing brain, stem cells called neuroblasts normally divide to create one self-renewing neuroblast and one cell that has a different fate.    From Wordnik.com.  [PhysOrg.com - latest science and technology news stories] Reference

In the most anterior segments, which make up the fly brain, neuroblast division continued long enough to make Ap clusters, but nonetheless the clusters didn't form.    From Wordnik.com.  [PLoS Biology: New Articles] Reference

Morphological analysis of vector control and APP cells showed neuroblast-like morphology with differentiated perikaria (arrows) and occasional short neurites (arrowheads).    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

The differentiation of specific nerve cell types in the thoracic segments results from spatial and temporal control of neuroblast lineages via an interplay of Hox, Pbx/Meis, and temporal genes.    From Wordnik.com.  [PLoS Biology: New Articles] Reference

A group of powerful pattern-generating genes called the bithorax complex, which is able to turn cell division off, is expressed at the proper time in the abdomen, and so, the authors tested its role in terminating abdominal neuroblast division.    From Wordnik.com.  [PLoS Biology: New Articles] Reference

Similarly, vector control as well as APP cells conserved their neuroblast-like morphology with differentiated perikaria and short neurites after treatment with GBE (.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference
