查询词典 embryonic cell

Results C/EBPαand C/EBPβexpressed differently in the outer root sheath,follicular papilla,hair matrix and sebaceous gland in embryonic period.The positive signals were chiefly distributed in the nucleˉuses.The expression of C/EBPαand C/EBPβwere found in the basal cell layer of outer root sheath and sebaceous gland in the new born and maturation phase,The expression in nucleuses of outer root sheat cells decreased with the differentiation but enhanced oppositely in the cytoplasm.

结果 C/EBPα和C/EBPβ分别在胚胎期毛囊外根鞘，毛乳头，毛母质及皮脂腺细胞的胞核内强表达；新生儿毛囊峡部下端外根鞘基底层细胞的胞核内也存在强表达，基底内层胞核阳性信号逐渐减弱；而成体毛囊核内阳性信号仅定位于峡部下端外根鞘基底层及皮脂腺基底层。

POU1F1 gene belongs to the family of POU gene. It plays a critical role in the embryonic differentiation and growth of the somatotropic, lactotropic, and thyrotropic cell lineages.

POU1F1基因是POU基因家族的成员之一，在胚胎分化和生长激素、催乳素、促甲状腺素细胞系的发育中发挥着重要作用。

We discuss some microRNA that are specificly expressed in embryonic stem cell and their regulating effect on self-renewal and differentiation .

主要讨论一些在胚胎干细胞中特异性表达的microRNA，以及这些microRNA 对胚胎干细胞自我更新和未分化状态的维持和继续分化增殖的调控作用。

Methods Transformed human embryonic tendon cells labelled by Brdu of 5×106/0. 4 ml and 1×107/0. 4 ml were injected subcutaneously to the right fore-limb subaxillary region of the nude mice,and 5×106/0. 4 ml tongue cancer cell (Tca 8113) as control group.

方法采用不同梯度细胞密度(5×106/0.4ml、5×107/0.4ml)，并用Brdu标记转化人胚腱细胞接种于裸鼠右前肢腋下，用舌癌细胞(5×106/0.4ml)与之对照，定时取材进行组织学观察。

Supervital NBS staining Nile Blue Sulphate , a lysosomotropic vital dye which stains embryonic apoptotic, but not necrotic cell death, is employed to identify the occurence and location of apoptosis.

活体胚胎的NBS染色 NBS是一种亲溶酶体染料，可使凋亡细胞着色，而坏死细胞不着色，因而可初步判定细胞凋亡发生的区域和程度。

Embryonic stem cell has the totipotency, but the induction mechanisms are not identified at present.

胚胎干细胞具有发育全能性，目前其定向诱导机制尚不明确。

AIM: The key of the human embryonic stem cell culture is to guarantee the totipotency and inhibit spontaneous differentiation.

Methods: RSCs were prepared from the retina of embryonic day 19 SD rats and labeled with different concentration of SPIO (Fe3+ 5.6μg/ml、11.2μg/ml、16.8μg/ml、22.4μg/ml). Prussian blue staining, electronmicroscope were used to evaluate the labeling efficiency of SPIO labeled RSCs. Cell proliferation and apoptosis were quantified by FACS, MTT and Turnel.

来源于19d胚胎大鼠的视网膜前体细胞，以不同浓度SPIO标记(Fe3+颗粒浓度为5.6mg/L、11.2mg/L、16.8mg/L、22.4mg/L)24～48h后，进行形态学观察和流式细胞技术、MTT和Turnel等技术分析，研究细胞增殖和凋亡情况。

The word "evolution," in fact, originally meant the unrolling development of an egg cell into an embryonic creature.

实际上，&进化&这个词，最初只是用来表示一个卵细胞分裂扩展成一个胚胎生物的过程。
