| The interplay between this information and a person's cellular machinery supplies a genetic programme controlling embryonal development, the processes of life and, possibly, death. |
| The differential diagnosis that should be considered in such a case include seminoma and embryonal carcinoma. |
| It usually indicates the presence of a teratocarcinoma, an endodermal sinus tumour or an embryonal carcinoma. |
| Undifferentiated embryonal sarcoma of the liver is a rare hepatic neoplasm that occurs mainly in children. |
| The embryonic stem cell is an almost mythically powerful and versatile human cell, fleetingly present during the earliest days of embryonal development. |
| It is similarly important to distinguish seminoma from yolk sac tumors because yolk sac tumors, like embryonal carcinoma, are radioresistant. |
