形态发生

So, HGF is also named as mitogenic factor、scattering factor、morphogen.

因此，HGF又称促有丝分裂因子、离散因子、细胞形态发生素或促迁移因子。

TGF-β familyis one type of morphogen. Once binding with the receptors, they transfer the signal into thenucleus through Smads, and regulated the transcription of target genes.

TGF-β家族成员就是一种重要的形态发生因子，它们与靶细胞的受体结合后，通过Smad家族蛋白将信号传递到细胞核里，调节靶基因的转录。

The Hedgehog morphogen governs cell differentiation and proliferation in a diverse array of patterning events in many animal species, ranging from insects to mammals. The seven-transmembrane protein Smoothened transduces the HH signal across the plasma membrane but molecular mechanisms of its activation are poorly understood. Zhao et al .

Hedgehog形态发生素在从昆虫到哺乳动物在内的很多不同动物物种的各种不同成形事件中决定细胞的分化和增殖。7-跨膜蛋白Smo跨越胞质膜传导Hh信号，但科学家对Smo激发的分子机制却很不了解。

Objective To study the morphogenesis of atrial septum and foramina secunda.

目的 探讨心脏房间隔与第二孔形态发生机制。

Methods Based on Hamburger and Hamilton staging, chick embryos were selected.The formation of atrial septun and foramina secunda were observed with microdissection and SEM.

按Hamburger和Hamilton分期法，选用第20～26期鸡胚，用显微解剖术和扫描电镜方法，观察房间隔与第二孔的形态发生过程。

The BarUPC program can export bar codes as bmp, gif, or jpg graphic files.

该barupc程序可以出口的条形码作为骨形态发生蛋白， GIF或JPG格式的图形文件。

In this article,the lastes t achievements in FGF10 regulating the morphogenesis of limbs,bronchiolung,pan creas,hypophysis,skin,teeth,submandibular gland and whit fat were reviewed.

就FGF10调控四肢、支气管-肺脏、胰腺、脑垂体、皮肤、牙齿、下颌下腺和白色脂肪等组织器官形态发生的最新研究进展进行综述。

No connection of these fibrils with other organs can be found.

经过紫杉醇药物处理后的细胞的形态发生了变化，结构呈现不规则状，且与基底没有纤维连接。

Gelatin microsphere is firstly made by encapsulating bFGF into gelatin by special manufacture process, then this microsphere was combinated into PLGA conduit or PLGA film.when used, we need only pack the injury peripheral nerve, injury spinal cord, wounded pars encephalic with the PLGA conduit. The conduit or film can slowly release buff which would be absorbed by around tissues.bFGF was already proved to be nutritious to the regeneration and alive of neuron and protect injury neuron.bFGF can also promote morphogenesia and division of nerve cell which would raise the survival rate of neuron, guide the generation of axon etc.bFGF is one of the important factors of sustaining the normal survival of cholinergic nerve.

使用时，只需将此材料贴敷外周损伤神经伤患处，脊髓伤口，或在脑部开颅手术后填充于术后创面，可有效地在伤口局部缓慢地释放并由机体组织吸收bFGF等神经营养因子。bFGF等已被证明具有神经营养作用，可促进神经元的再生与存活，保护受损的神经元。bFGF等对神经细胞兼有促进形态发生与分裂作用，具有提高神经元的成活率、诱导轴突向外生长等功能，是维持前脑基底部胆碱能神经元正常生存的重要因素。

Itplayed a role in the morphogenesis and ductal migration of mammary epithelial cells, promoted theresponsiveness of these cells to lactogenic hormones in vitro and induced the differentiation ofmammary epithelium into secretory lobuloalveoli.

Heregulin-α是细胞间信号蛋白，它可增强体外培养的乳腺上皮细胞对催乳素的敏感性，在乳腺上皮细胞形态发生、导管形成，以及诱导乳腺上皮细胞分化成分泌腺泡中扮演了重要角色，对乳腺发育和乳腺功能调控具有重要作用。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
