In addition, under appropriate culture conditions, ES cells differentiate into a broad spectrum of cell types and when injected into immunocompromised animals, they form teratomas composed of multiple lineages.

Fatty, cystic mass and cystic teratomas showed particularly characteristic signs on MRI.

If these tumors are mostly solid, then they are often "immature" teratomas with less differentiated tissue and are more aggressive.

如果此肿物中大多数为实性物质，那么经常称为&不成熟性畸胎瘤&，其内含有未分化组织成分且更具侵袭性。

They formed several kinds of tissue in the culture dish and produced tumors called teratomas when they were injected under the skin of immune-compromised mice--both classic characteristics of ES cells.

它们在培养皿中形成了几种肌体组织并且当他们被注射到免疫能力较差的老鼠皮下组织的时候，就会产生一种畸胎瘤。这也是胚胎干细胞的典型特征。

The split between the two groups can hardly be papered over.
