The measurements used are fork length, head length, upper jaw length, snout length, length of dorsal fin base and anal fin base and the distances from the tip of snout to insertion of dorsal fin, to pectoral fin, to ventral fin and to hard margin of preopercle.
此所用於分析之外部非体节形质计有:尾叉长、头长、上颚长、吻长、眼径、背鳍基底长、臀鳍基底长以及吻端到前鳃盖骨后绿、背鳍起点、腹鳍起点、臀鳍起点等11个形质。

RESULTS: After co-culture, morphology of bone marrow stromal stem cells was changed, showing that flat cells began to retract and became spindle-shaped and some cells displayed a linear arrangement like Schwann cells.
结果:共培养后的骨髓基质干细胞形态发生改变,原来宽大扁平的胞体开始收缩,细胞胞体呈梭形,部分细胞类似施万细胞呈线性排列。

Results:(1)The primary cells in cultured were observed from the edge of the cultured tissues after 10-15 days. The cultured cells were round , oval, fusiform and multiangular.
结果(1)组织块培养10-15天后可见细胞从其边缘向外生长,倒置显微镜下呈梭形、圆形、椭圆形,并有多个突起,电镜下可见表面有较多的微绒毛,细胞间缝隙连接,胞质内见较多次级溶酶体。

RESULTS: The passaged MSCs exhibited uniform appearance in fusiform shape, and their growth was slowed down after 9 passages, exhibiting cytoplasm vacuolization and body enlarging.
结果:传代培养的骨髓间充质干细胞形态均一,呈梭形、纺锤形,克隆样生长,培养至9代后生长减慢,并出现胞浆空泡化、胞体变大等老化现象。

Before treatment,there are abundant microvtlli on the cell surface,many filoplodia on the cell rim,few of endoplasmic reticulums , Golgi complexes and mitochondrions with abnormal structure and lots of free ribosomes in the cytoplasm. The shape of nucleus is irregular with high nuclear-cytoplasmic ratio, many dark pellets of heteromatin and a few of nucleoluses in which there ar...
经1.5×10~2g/L地塞米松处理后,细胞表面微绒毛和丝状伪足显著减少或消失,出现皱褶状和小泡状结构;细胞核形规则,核质比值减小,异染色质团块减少,核仁数目减少、结构致密;细胞质中粗糙型内质网、高尔基体、线粒体数量增多,形态结构典型,游离核糖体减少,这些变化说明地塞米松改变了MGc80-3细胞的超微结构特征,具有明显的诱导分化作用。

Four weeks later, in the baicalin group, some spindle-shaped UCB-MSCs began to present shrinkage, with slender processes on the cell edge, and some UCB-MSCs tended to be spherical-, conical-, and triangle-shaped appearance, with many slender processes on the pseudopodia.
细胞形态学观察:脐血单个核细胞培养第2~3天开始贴壁生长,2周左右达高峰,3周后细胞生长达80%~90%融合,此时脐血原始间充质干细胞呈较均一的长梭形。4周后,黄芩苷组原来呈梭形的胞体一部分发生收缩,细胞边缘出现细的突起;一部分胞体逐渐近似圆形、锥形、三角形,伪足有多个细长突起。
