nervous system
• neural progenitor cells prematurely exhibit the cell cycle and become migratory
• mis-segregated chromosomes with DNA bridges located at the cleavage furrow
• however, karyotypes are normal
• at E15.5 and E16.5 with some precursor cells located outside the ventricular zone and subventricular zone
• POU3F2-expressing L2-5 neurons
• CUX1-expressing L2-4 neurons
• due to increased apoptosis
• however, deep layer neuron numbers are normal

cellular
• mis-segregated chromosomes with DNA bridges located at the cleavage furrow
• however, karyotypes are normal
• in the cortex at E15.5, abundant in the germinal zones and intermediate zone
• marginally by E17.5
• associated with increased DNA damage determined by gammaH2AX staining
• however, apoptotic cells are largely absent from the cortical plate
• neural progenitor cells prematurely exhibit the cell cycle and become migratory

growth/size/body
• less severe than in mice with the conditional activated by Emx1tm1(cre)Krj

homeostasis/metabolism

immune system
• mis-segregated chromosomes with DNA bridges located at the cleavage furrow
• however, karyotypes are normal

hematopoietic system
• mis-segregated chromosomes with DNA bridges located at the cleavage furrow
• however, karyotypes are normal
