|
• born alive but do not survive beyond P10
|
|
• increase in the number of astrocytes in the cortex at E18.5 and P7
|
|
• increase in apoptosis at E13.5, primarily located in layers V-VI of the cortex
|
|
• in culture ventricular zone cells are less likely to develop into neurospheres of greater than 50 um in diameter indicating impaired proliferation
|
|
• decrease in the number of early born layer V and VI neurons at E12.5
• decrease in the number of Ctip2+ layer V and VI neurons, Tbr1+ layer VI neurons and Tbr2+ basal progenitors in the cortex at E14.5 and E16.5
• increase in the number of Cux1+ and Satb2+ upper layer neurons at E18.5
• smaller cortex at E18.5 and P7
• severe reduction in the number of Ctip2+ layer V and VI neurons at P7
|
|
• increase in apoptosis at E13.5, primarily located in layers V-VI
|
|
• in culture neural progenitor cells from E14.5 embryos more readily differentiate into astrocytes
|
|
• premature acceleration of the production of late born upper layer neurons and deceleration of the production of early born deep layer neurons in the cerebral cortex
|
|
• impairment of early neurogenesis indicated by decrease in the populations of deep layer neurons at E18.5
• premature acceleration of the production of late born upper layer neurons and deceleration of the production of early born deep layer neurons in the cerebral cortex
• partial reduction in the migration of GABAergic neurons into the dorsal telencephalon at E18.5
|
|
• increase in the number of Brn2+ layer II-III neurons in the cortical plate at E14.5 and E16.5
|
|
• decrease in the number of basal progenitors (Tbr2+) at E11.5 and E12.5
|
|
• decrease in the number of early born layer V and VI neurons at E12.5
• decrease in the number of Ctip2+ layer V and VI neurons, Tbr1+ layer VI neurons and Tbr2+ basal progenitors in the cortex at E14.5 and E16.5
