If a chemical prevents asymmetrical divisions of neuronal stem cells in the neural tube of a fish embryo, then
A) neuroblasts and gliablasts will not be produced.
B) microglia will not be produced.
C) excessive myelination will result.
D) immune function will be compromised.
E) blood-forming stems cells will replace neuronal stem cells.

Question

Quizplus · Accepted Answer

Asymmetrical divisions of neuronal stem cells in the neural tube of a fish embryo are required to produce neuroblasts (cells that differentiate into neurons) and gliablasts (cells that differentiate into glial cells). Without these asymmetrical divisions, neither of these cell types would be produced.
