角质层的

Normally, skin on the scalp undergoes a process called keratinization to maintain cell turnover.

在头皮表面较薄的角质层未完全角质化，便会从表皮脱落，形成头皮。

From the outside to the inside , the body skin is divided into the stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm and stratum basale , after through stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm EGF can reach the stratum basale: accelerate the basal cells prpliferation and differentiation , reverse matured cells' differentiation to make stem cells that will form a " stem cells island " with a certain amount , which accelerate the generation of new cellls , make senescent cells keratinize and shed rapidly , make broken and denatured collagen fibers and elastic fibers repaired , so the skin's elasticity increase , and the wrinkles calm down or disappera gradually .

体表皮由外及里共分为角质层、透明层、颗粒层、棘细胞层、基底层，EGF可以通过透明层、颗粒层、棘细胞层深入肌肤基底层，加速基底层细胞增殖分化，将已经分化成熟的细胞逆分化成干细胞，当达到一定量时，便会形成&干细胞岛&，加速新细胞的生成，让衰老细胞快速角化、脱落，已断裂、变性的胶原纤维和弹性纤维得到修复，皮肤弹性增加，皱纹逐渐平复、消失。

Lamellar granules function in this space, primarily at the interface between the granular and cornified cell layers.

间隙主要是在颗粒层和角质层细胞的交界处，薄层状颗粒在此间隙发挥作用。

Startum lucidum: between horny layer and stratum granulosum, is made up of 2-3 layers of flat enucleated and vaguely bounded hyaline cells, the eleidin in them has a natural barrier action of preventing water and electrolyte pass through .

透明层：位于角质层和颗粒层之间，由2-3层扁平无核而界线不清的透明细胞组成，内含角母蛋白，有防止水及电解质通过的天然屏障作用。

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

结果：CDK4、P16均表达于胆脂瘤上皮的棘细胞层、颗粒层和角质层，阳性率分别为68.6%、88.6%，高于对照组(前者P=0.011，后者P=0.02)。

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。

Besides, the cuticles that resist external invasions can be ridded of with fruit acids so that DNA vaccine wrapped with liposome can pass the skin.

而肤表面的角质层，会将很多外来的东西阻挡在外，因此只要先透过果酸把角质层去除，被微脂体包覆的DNA疫苗就可经皮传输进入体内。

RESULTS: Transplanted AS had a favorable fusion between tissue-engineered skin and self-skin on the 3rd day after grafting with a few of ingrowths of capillaries.

结果：AS组在移植第3天，移植的组织工程皮肤与自体皮肤能够很好地融合，有少量毛细血管长入移植物，皮肤移植物颜色与自体皮肤颜色接近；随着时间的延长，移植物中毛细血管的数量逐渐增多，表皮层清晰可见基底层、棘细胞层、颗粒层和角质层，角化现象加强，有角化物脱落；真皮层细胞数量增多，网架逐渐降解，分泌的细胞外基质成份增多；第14天，创面基本愈合；修复区皮肤颜色与正常皮肤颜色非常接近，瘢痕很小，无需进行二次植皮。

The pollen grains of yew tree are directly fallen on the micropyle by wind and enter pollen chamber at the top of nucellus through pollination drops, a sugary exudation rich in nutritious materials at the micropyle.

红豆杉叶片外表面覆盖较厚的角质层和表面蜡质，具有乳头状角质钉，以及长条形或顶端分叉的角质突起。

The outer surface of yew tree leaf is covered by a thick cuticle and epicuticular in the top. The surface view of epidermal cells appears square or rectangular on the abaxial and adaxial leaf sides.

红豆杉叶片外表面覆盖较厚的角质层和表面蜡质，具有乳头状角质钉，以及长条形或顶端分叉的角质突起。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
