角质

Result showed that the epidermis dominant the morphogenesis changes. Mesenchymal is subdominant.β-catenin expression begin from horny placode epidermis stage and go up increasingly to peak value and maintain in hair follicle. The range of mesenchymal change is less.

结果表明，牦牛角的形态发生按照角基毛囊和角质外鞘发生与否分为5个阶段：角原基前期(Ed≤60)表皮增厚，无毛囊发生；角原基中期(Ed60~140)表皮持续增厚，有少量毛囊发生；角原基后期(Ed140~250)表皮变薄，大量毛囊发生；肉角期(≤0.5 a)真皮乳头发生；成角期(≥0.5 a)形成角质外鞘。

Features: It can tranquilize, dredge and shrink pores, reduce sebum secretion elements to remove facial oil, improve water-oil balance of skin, promote metabolism of keratins of skin and loosen aged and waste keratins, and thus promote skin absorption with a good moisturizing effect, leave skin look healthy, refreshing and non-oily.

产品特性：镇静、畅通及收敛毛孔，减少皮脂分泌的元素去除面部油光，改善肌肤的水油平衡，促进角质代谢，松动老废角质，从而促进肌肤的吸收，并提供良好的保湿效果，使肌肤看起来健康清爽，不泛油光。

Keratolytic rejuvenation: gently soften and remove the aged horniness on the skin surface and in the pore, dredge and astringe pores, smoothen the nutrition channel of cortex to ensure better nutrition absorption.

去角质美肤：轻柔软化并清除皮肤表层及毛孔内的老化角质，疏通并收敛粗大的毛孔，畅通表皮层营养通道，使营养更好吸收。

In this paper, three kinds of dispersed cordaitean cuticles are described in detail from the Permian coal-bearing strata in China.

到目前为止，中国华夏植物区总共描述了4种科达植物原位角质层和3种分散角质层。

Up to now, four types of cordaitean cuticles in situ and three types of dispersed ones have been reported from the Cathaysian Flora in China.

到目前为止，中国华夏植物区总共描述了 4种科达植物原位角质层和 3种分散角质层。

These names reflect the changing appearance of the keratinocyte as it differentiates into a cornified cell.

这些名称反映了角质形成细胞分化成角质细胞的形态变化。

Xerophytes tend to have thick cuticles, and dry conditions often induce cuticular thickening.

角质层的厚薄因植物的种类和生活环境而异，生长在干燥和阳光充足环境下的植物有较厚的角质层，而生长在水中或阴湿环境下的则较薄。

Thus, in the process of chronic eczematous dermatitis, the apoptosis of keratinocyte is not only a turning point, but also a new target of drug screening.

因此，角质形成细胞的凋亡为湿疹性皮炎慢性化的转折点，阻断角质形成细胞的凋亡可以减轻湿疹慢性化进程的发生，从而为湿疹性皮炎的治疗提供了一条新的途径，成为药物筛选的一个新靶点。

These transgenic cells were able to secrete hEGF protein to certain extent, and have the biological activities to enhance the growth rate of Hacat cells in vitro. Conclusion: Adult epidermal keratinocytes in vitro transfected with exogenetic hEGF cDNA can express and secrete active hEGF.

质粒pcDNA3.1-hEGF在脂质体介导下成功转染成人皮肤角质形成细胞，转基因细胞能分泌有生物活性的EGF；体外培养的成人皮肤角质形成细胞可见少量EGF分泌。

Keratinous layer, the outer of epidermis, is made up of flat keratinous epithelia that have degenerated lifeless.

角质层是表皮最上一层，由角质化的扁平上皮细胞组成，它们的结构都已退化，无生命，经常脱落形成皮屑，该层含水量很少。
