| graded | The onset of cad-11 expression in the somites was strictly correlated with the formation of new somites. In each cycle of new somite formation, the first expression of cad-11 occurred at the caudal region of a cluster of newly condensing mesenchymal cells. As these cells formed closed epithelial vesicles, the entire somite structures became stainable for cad-11. However, at later stages, the dermomyotome gradually lost cad-11 expression, leaving only the sclerotome and core cells positive. |
