What CNS stem cell creates a scaffold traversing the developing cortex that guides migrating neurons to their final location upon exiting the ventricular zone? neurons O radial glia O neural crest O astrocytes Question 3 1 pts The loss of embryonic BMP4 expression in the developing dorsal ectoderm is most likely to cause which of the following problems? O Dorsal localization of normally ventral neuronal subtypes in the spinal cord O Enhanced neuronal specifcation in the DRG Anterior localization of normally posterior neuronal subtypes in the spinal cord O Absence of myelinating glia What CNS stem cell creates a scaffold traversing the developing cortex that guides migrating neurons to their final location upon exiting the ventricular zone? neurons O radial glia O neural crest O astrocytes Question 3 1 pts The loss of embryonic BMP4 expression in the developing dorsal ectoderm is most likely to cause which of the following problems?
