If these tumors are mostly solid, then they are often "immature" teratomas with less differentiated tissue and are more aggressive.
如果肿瘤以实体为主，则常是未成熟畸胎瘤，分化程度较低，并有更大的侵袭性。
However, the overall difference between them is not great, so this benign neoplasm mimics the normal tissue quite well and this, therefore, well-differentiated.
然而它们之间的不同不是很大，因此这种良性肿瘤与正常的组织相似性较大，分化较好。
Aim: to investigate the clinical significance of estrogen receptor (er) expression in differentiated thyroid carcinoma (DTC) tissue.
目的：探讨甲状腺分化癌(DTC)组织中雌激素受体(ER)表达的临床意义。
The photosynthetic and supportive cells tend to be organized linearly, but a thallus lacks such differentiated specialized structures as stem, leaves, and conducting tissue.
那些可进行光合作用和所维生的细胞呈线形结构，但原植体则无根、茎、叶的分化，无输导组织。
Embryonic stem cells: embryonic stem cells known as the "universal cell", which can be differentiated skin cells and other tissue cells.
胚胎干细胞：胚胎干细胞被称为“万能细胞”，它可以分化出皮肤细胞等各种组织细胞。
When activated by maturation factors including VEGF, the pre-osteoclasts differentiated into mature osteoclasts and chew up bone tissue, providing the tumor new space to grow.
一旦由包括VEGF在内的促成熟细胞因子活化后，破骨细胞的前体细胞可以分化成为成熟的破骨细胞，破坏骨组织，给肿瘤细胞的生长腾出空间。
The mesophyll is not differentiated into spongy and palisade tissues, but mesophyll near midrib in tip and middle parts of leaf is often lengthened to appear as palisade-liked tissue.
叶肉没有海绵组织和栅栏组织的分化，但叶尖部和叶中部中脉附近的叶肉细胞常伸长，类似栅栏组织细胞。

The lesions located in the mucosal tissue with polyp-like or papular appearance, so they should be differentiated from other neoplasms or non-neoplastic lesions.
由于病变组织位于黏膜组织内呈丘疹样或息肉样外观，因此需从临床及组织学角度与多种病变相鉴别。
