As similar defects are not exhibited by mice that experience systemic inhibition of NF-B, we postulated that the morphogenetic defects in IKK--deficient mice are not caused by reduced NF-B activity but instead are due to failed epidermal differentiation that disrupts proper epidermal–mesodermal interactions.

因为类似的缺陷没有出现在经历了全身NF-B抑制的小鼠，作者推断IKK缺失小鼠的形态发生缺陷不是由于NF-B活性降低引起而是因为可以破裂专属表皮－中胚层相互作用的表皮分化失败引起。

However, hair follicle stem cells prefer hair destiny in vivo, unless the injury of epidimal or sytogland occurs. In 1990, Cosarelis et al. proposed "The Bulge activated hypothesis", they think the signal moleculars emit from the dermal papillar induce the downward migration and differentiation of hair follicle stem cells.

然而，体内正常情况下毛囊干细胞首先向毛发谱系定向分化，只有在表皮或皮脂腺受到损伤时，它们才进行程序重组而向表皮或皮脂腺方向分化。1990年，Cosarelis等提出毛囊的&隆突激活假说&，认为来源于毛乳头的信号因子触发了毛囊干细胞向下迁移并分化，从而维持了毛发周期的正常循环。

Compared studies of routine DIF and DIF of 1mol/L Nacl-separated patients skin and IIF using 1mol/L NaCl-separated normal human skin as substrate were clone in 19 patients with bullous pemphigoid and 5 with epidermolysis bullosa acquisita.

对19例大疱性类天疱疮和5例获得性大疱性表皮松解症病人进行了常规DIF、1mol／LNaCl分离表皮DIF和1mol／LNaCl分离正常人皮肤IIF的对比研究。

Both of them originated from the protodermal cells and formed four cells through two successive periclinal divisions.

两类表皮毛的原始细胞均起源于叶原基或幼叶的原表皮细胞，经过两次垂周分裂形成四细胞。

The significant differences existed in lower epidermis among materials:in 2 splitting-resistant cultivars,their anticlinal walls had clearly sinuous ridges and the periclinal walls had equal thick ornamentations of cuticles; the defensive cells were rounded cuticles of projected ridges,and epidermal cells were covered with dense powder.

材料间下表皮微形态存在较显著的差别：耐裂材料的垂周壁上有明显的波状嵴，平周壁上有加厚的条纹状角质层纹饰，保卫细胞四周角质层褶皱较多、起伏较大，表皮细胞上覆盖有大量的粉状或颗粒状蜡质。

The promeristem is consisted of three groups of initial cells, which have typical cytological characteristics of meristem cells. The primary meristem is composed of calyptrogens, primordial epidermises, periblems and pleromes. Both the calyptrogens and the primordial epidermises initiate from the same layer of initial cells.

原分生组织由3群原始细胞组成，其细胞具有典型分生组织的细胞学特征；初生分生组织包括根冠原、表皮原、皮层原和中柱原，其中根冠原和表皮原具有相同的起源。

A challenge in such a use is expansion and directed seeding in itro, requiring proliferation and surial, and directed migration, respectiely, prior to functional differentiation. The epidermal growth factor receptor is the prototypal growth factor receptor and elicits these responses from a wide ariety of stromal, epithelial, and endothelial cells.

对于这一种细胞的应用所面临的挑战是在功能性分化前在体外的直接种植和扩增、增殖及分化以及导向性迁移等，表皮生长因子受体是一种原型生长因子受体可以在间质细胞、表皮细胞及内皮细胞中引出上述效应。

Based on these characteristics observed, species in Pteridaceae tended to accumulate and deposit silica in long cells in lower epidermis and forming spicular cells. This might helps them to enhance the supporting function of their lateral veins.

综合以上特徵推测，凤尾蕨科倾向将二氧化矽堆积於叶下表皮与叶脉平行之表皮细胞上，并形成矽异形细胞，该特徵可能与加强叶片的支持力有关。

The results showed that NaCl stress decreased the seedlings fresh mass and dry mass significantly. Under NaCl stress, the relative contents of Na(superscript +) and Cl(superscript -) in cells increased significantly, but the increment somewhat differed with different tissues. In root and stem, epidermal cells had the greatest increment, followed by cortex cells, and stelar cells; while in leaf, epidermal cells had the greatest increment, followed by cortex cells, spongy tissue cells, and palisade tissue cells.

结果表明：NaCl能显著降低长春花幼苗的鲜质量和干质量；对根、茎和叶片横切面X射线微区分析表明，NaCl胁迫导致长春花体内各组织细胞中Na和Cl相对含量显著增加，但在各器官、组织中分布稍有不同：与对照相比，根和茎中都是表皮细胞中增加幅度最大，中柱细胞次之，皮层细胞最低；在叶片中亦是表皮细胞增加幅度最大，依次是皮层细胞、海绵组织细胞及栅栏组织细胞。

Objective:To study the expression and clinical significance of E-cadherin and epidermal growth factor receptor proteins in supraglottic carcinoma.

目的：探讨表皮钙粘素(E-cadherin，E-cd)和表皮生长因子受体在声门上喉癌的表达及其临床意义。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
