OBJECTIVE: To summarize the characterization of epithelial cells and epidermal stem cells and their interaction in wound healing so that we can recognize the mechanisms of scarring from histomorphology, biochemistry and molecular variations.

目的：总结上皮细胞与表皮干细胞的特征以及在创伤愈合中的相互交织作用，从形态学和分子生物学上提高对瘢痕形成机制的认识。

Conversion to filaggrin takes place in the granular layer, and thi froms the electron-dense interfilamentous protein matrix of mature epidermal keratin.

Insect alkaline phosphatases are distributed in such insect organs and tissues as head, salivary gland, intestine, Malpighian tube cuticule, haemolymph, fat body, reproductive system and appendage. They may be involved in the process of insect development, nerve conduction, hormone synthesis, substance metabolism and diapause, and caste formation in social insects, etc.

碱性磷酸酶存在于昆虫的头、唾液腺、肠道、马氏管、表皮、血淋巴、脂肪体、生殖系统、附肢等部位，广泛参与了昆虫的发育、神经传导、激素合成、物质代谢、滞育、社会型昆虫亚种形成等过程。

These results revealed that the pollen chamber developmental pattern passed through four phases. Firstly, a group of nucellar cells at the micropylar end elongated longitudinally. Thereafter, the uppermost nucellar cells at the micropylar end initiated PCD; and these elongated cells undergoed PCD in a basally and laterally oriented direction to form a cavity.

贮粉室的形态发生可分为4个阶段：最先是位于珠孔端的几层珠心细胞纵向地伸长；接着，珠孔端最顶部的珠心细胞发生PCD；然后，那些已经纵向伸长的珠心细胞向基地和侧向地依次发生死亡，产生贮粉室空腔；最后，珠孔端的珠心表皮细胞发生开裂，形成贮粉室的开口。

Of ferns having sporangia that arise from a group of epidermal cells.

具有由一组表皮细胞形成的孢子囊的。

The results showed:(1) The histological changes of KC were in fact a wound-repair process;(2) The increased melanin in KC coordinated with "multi-overlapping screen" effect, a result of multiple layers of "supranuclear cap", was the direct cause of hyperpigmentation of the graft and (3) The hydrolytic disturbance of melanin in KC and the longer life span of the KC were probably the important reasons for the increase of melanin in the epidermis.

结果表明，角朊细胞的组织学改变实际上是一个损伤后修复的过程；角朊细胞内黑色素含量增加及出现的多层次的&核上帽&状分布而形成的&多重帘幕&效应，是皮片过度色素化的直接原因；黑色素在角朊细胞内的降解障碍及角朊细胞更新周期延长可能是表皮内黑色素含量增多的重要原因。

Above them the stars burned, rotating occasionally as the treeship changed its pitch or yaw, while to either side a solid sphere of foliage curved away like the green skin of some great fruit.

在他们头顶，群星闪耀着光芒，有时当巨树之舰改变角度或航向，星辰也随之旋转。两边，树叶弯曲形成球体状，像是巨大水果的绿色表皮。

A waxlike,water - repellent material present in the walls of some plant cells and forming the cuticle,which covers the epidermis.

角质一种出现在某些植物细胞的细胞壁上的蜡状抗水物质，它形成覆盖在表皮外面的角质层

Objective To investigate the migrating effect of adipose derived stem ceils on the wound model of human epidermal keratinecyte.

目的 探讨脂肪干细胞促进人表皮角质形成细胞创面模型愈合的可能性。

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％。
