| In the tertiary state of development endodermal cells deposit lignified cell wall material onto the suberin lamella. |
| The tumor demonstrated predominantly mature ectodermal, mesodermal, and endodermal elements. |
| During the embryonic stage, the tonsils arise from the second pharyngeal pouch as buds of endodermal cells. |
| It usually indicates the presence of a teratocarcinoma, an endodermal sinus tumour or an embryonal carcinoma. |
| We still consider this a benign tumor because no endodermal sinus components were evident. |
| Furthermore, they suggested that such neuroendocrine carcinomas might be of endodermal rather than neuroectodermal derivation. |
