| The most interesting and most perplexing question is how ectodermal glands can be derived from what has been thought to be endodermal and mesodermal derivatives. |
| Impregnation of endodermal and hypodermal walls with suberin and lignin should reduce the diameter of interfibrillar spaces. |
| The growth of the new tip into the cortex first pushes out the endodermal sheath, if one is present, and then bursts it. |
| The tumor demonstrated predominantly mature ectodermal, mesodermal, and endodermal elements. |
| He coaxed some iPS cells into becoming liver endodermal cells. |
| Furthermore, they suggested that such neuroendocrine carcinomas might be of endodermal rather than neuroectodermal derivation. |
