abnormal cardiac neural crest cell migration ( J:334073 )

• lack of tdTomato cNCCs in the proximal outflow cushion is less severe at E11.5; abundant cNCCs are found in the distal and intermediate outflow cushions, but not in proximal cushions, consistent with delayed migration

• moreover, number of Pax3Cre-tdTomato expressing cells that co-express SOX10 is markedly decreased and the linear migration pattern from the neural tube toward the heart is disrupted; most of tdTomato positive-expressing cells lacking SOX10 expression are located rather peripherally

• N-cadherin staining showed upregulation of N-cadherin expression in migratory NCCs at E8.5 and E9.5
