| 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. |
|
| In the tertiary state of development endodermal cells deposit lignified cell wall material onto the suberin lamella. |
|
| Impregnation of endodermal and hypodermal walls with suberin and lignin should reduce the diameter of interfibrillar spaces. |
|
| 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. |
|
| Neither ectodermal nor endodermal components were identified in the sections examined. |
|
| The growth of the new tip into the cortex first pushes out the endodermal sheath, if one is present, and then bursts it. |
|
| It usually indicates the presence of a teratocarcinoma, an endodermal sinus tumour or an embryonal carcinoma. |
|
| Most cnidarian muscles, however, are thin sheets at the base of ectodermal and endodermal layers. |
|
| 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. |
|
| He coaxed some iPS cells into becoming liver endodermal cells. |
|
| Whether derived from an archenteron or formed by folding of the endodermal sheet, the canal initially does not possess an opening at its anterior end. |
|
| One reason for choosing the stomach was to understand the endodermal developmental process better, for the details of the stomach's genesis were obscure when the team started work. |
|
| These include the degeneration of zooxanthellae in situ, the expulsion of zooxanthellae by the mesenteric filaments and from the mouth, and expulsion via the c½lentron of whole endodermal cells with their zooxanthellae. |
|
| It consists of five paired mesodermic arches, each separated by an endodermal pouch and an ectodermal cleft. |
|
| The extent of this DNA methylation was similar in endodermal, mesodermal, and ectodermal tissues, indicating that genistein acts during early embryonic development. |
