原始细胞

Epithelial cells and muscle is connected to a primitive phenomenon, Hydrozoa in some hard-jellyfish and jellyfish as well as most bowl Anthozoa animals, epithelial cells can be no contraction of the above-mentioned processes.

上皮细胞与肌肉相连是一种原始现象，水螅纲中的有些硬水母以及大多数钵水母和珊瑚纲动物，上皮细胞没有上述能收缩的突起。

Embryological observations on Crawfurdia delavayi, Tripterospermum cordatum, T. chinense, Gentiana striata and Pterygocalyx yolubilis show that the group under study is greatly diverse in differentiation and development of anther wall, type of ovule and placentae, synergid and antipodal cell in embryo sac, testa and embryogeny etc. The embryological characters are different among Crawfurdia, Tripterospermum and Gentiana Sect.

胚胎学 本文对披针叶蔓龙胆C.delavayi、双蝴蝶T.chinense、峨眉双蝴蝶T.cordatum、条纹龙胆G.striata和翼萼蔓P.voiubilis作了较详细的胚胎学研究，这些类群在花药壁的分化和形成、胚珠和胎座类型、卵器中的助细胞和反足细胞、种皮以及胚发育等特征上存在差异，并且在胚胎学特征上各自拥有原始和进化的性状。

The survival time of the mice administrated retrobulbarly was 16±2d, the count of white blood cells and the percentage of immature granulocyte and monocyte obtained from tail vein did not raise, myeloblast and monoblast percentage of bone marrow was also in normal range.

由球后途经接种的小鼠其生存时间为16±2d，外周血白细胞计数、未成熟粒单核细胞百分率及骨髓原始粒单核细胞百分率一直处於正常范围内。

The m aturation, regression, and progression of neuroblast and embryonic n eural crest cells might be promoted by bcl-2 protein.

bcl-2基因异常表达可能与神经母细胞或原始神经嵴细胞逃脱凋亡，不能正常成熟或消退，而发展成NB及NB的进展有关。

It indicated that in the developmental biologic point of view,very archaic anatomical structure-loose connective tissue play an athletic and energetic role in organisms\' metabolic process.As cell signal transduction is concerned, subcutaneous fascia of acupoint is unspecialized.

体液等调节以外，筋膜结缔组织支架的存在可能构成另外一个较为原始的调控网络。3、在正常的疏松结缔组织中，ERK细胞信号转导蛋白一直有非磷酸化和磷酸化的表达，而这种表达又与细胞的增值和分化有关。

Result The BMP15 protein had no expression in oocytes of primary, secondary, antral follicles as well as granulosa cells and follicular flu. It was also detected in corpora lutea during early luteolysis at high level, but it was observed in atretic follicle at low level.

结果］BMP15蛋白在原始卵泡中没有表达，在初级卵泡、次级卵泡和有腔卵泡卵母细胞及有腔卵泡颗粒细胞和卵泡液中均有表达，在黄体溶解早期也有表达，但是在闭锁卵泡中的表达则受到抑制。

Results (1) Primary callus came into being 3 days after operation. Mesenchymal cells from peripheral tissues around the primary callus were differentiated into chondrocytes 1 week later. Endochondral ossification was going on then. Bridging callus was formed in the fracture sites 4 weeks after operation.

结果 (1)伤后3 d开始形成原始骨痂。1周时肉芽组织中的间质细胞开始分化为软骨细胞，软骨形成后再进行软骨内化骨。4周时形成连接骨折端的桥接骨痂。

At the fifth passage, two cell strains were made into cell suspension at l×10^9L^(-1). 0.5 mL was subcutaneously incubated at the inguina of each rat for 8 weeks. Amplified cells were cultured in PGC culture medium and non-adherence culture flask till idiosome formed, adhered and differeotiated.

体内实验取连续传5代的2个细胞株，分别制备浓度为l×10^9L^(-1)的细胞悬液，于每只小鼠两侧腹股沟处皮下各接种0.5 mL，培养8周体外分化采用无私附特性的培养瓶和除去白血病抑制因子的原始生殖细胞培养液，以脱饲养层法悬浮培养扩增的细胞，直到拟胚体形成及贴壁分化。

FGFR4 expression was faint in renal vesicle and primitive tubules of S-shaped body, irrecognizable in urteric bud and podocyte of C-stage, negative in mesenchyme and condensing mesenchyme.

胚胎肾发生带内FGFR4表达微弱，肾囊泡和S型小体的上支和中间支，即原始肾小管上皮细胞部位有微弱表达，间充质、压缩间充质未见表达，输尿管芽及其末端壶腹和C-期足细胞表达不明显。

This process, called vasculogenesis ,involves the de novo differentiation of endothelial cell from mesodermal precursor to form the primitive blood vessel network.

血管生成是指在胚胎发生和器官形成过程中，从中胚层内皮细胞中分化出新的内皮细胞以形成原始血管网的过程，仅见于胚胎发生的早期，出生后即停止。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
