The astrocyte marker gfap and oligodendrocyte marker mbp were not detected . nor the endoderm and mesoderm markers 胶质细胞标志基因gfap 、 mbp未检测到,其他胚层的标志性基因也没有表达。

The research of relationship between the kidney in the sense of tcm and mesoderm from the influence of tonifying the kidney on apoptosis of fibroblast cells of kidney - deficient rats 从补肾对肾虚大鼠成纤维细胞凋亡的影响看中医肾与中胚层的相关性

Because one patient only suffers from iris coloboma instead of aniridia , we would like to propose that the primary embryological defect is due to aberrant development of mesoderm 网膜发育不良,角膜变性,白内障及续发性青光眼是常见使视力变坏的因素。

At the same time , growth factors have relation to genesis of tumor . fibroblast growth factor ( fgf ) can promote proliferation of tissues derived from mesoderm or neuroectoderm and many tissues and cells can secrete fgf 成纤维细胞生长因子( fgf )能够诱导中胚层和神经外胚层来源细胞的增殖和分化,许多组织和细胞都可以分泌fgf , fgf可以促进多种细胞的生长和分化。

In the early neurula , cortactin staining signals were detected in the developing primodium of forebrain as early as 10 . 5 hpf ( hours post fertilization ) , at the same time the tailbud areas were highly stained too . later , the staining was concentrating in the developing neural rod while paraxial mesoderm derivatives were not stained 在早期神经胚,神经系统中的前脑原基最先出现染色,并保持头尾两端处染色最强的图式,随后,染色集中分布在发育中的神经龙骨中,但近轴中胚层细胞没有染色。

Whole mount in situ hybridization showed that amphihmgb transcripts were present ubiquitously in the early embryos from zygote to neurula , but they decreased gradually in mesoderm and endoderm and neural tube with development , and became restricted to epidermal cells in the hatched larva . it appear s that hmgb plays a role in the mitosis and differentiation of embryonic cells . another amphioxus cdna , amphiubf80 , encoding ubiquitin / ribosomal fused protein s27a , was isolated from the gut cdna library of b . belcheri tsingtauense S004cdna序列编码一个156个氨基酸残基组成的蛋白质,与人的泛素蛋白ubf80具有较高的氨基酸序列同源性( 145 / 156同源) ,且该蛋白具有泛素蛋白ubf80所共有的两个结构域,即由72个氨基酸组成的泛素介导的蛋白降解结构域和由48个氨基酸组成的核糖体蛋白s27a结构域。

Ranging from 100 to 200 microns across , the width of several human hairs , these microscopic fossils are surprisingly complex and constitute almost a textbook example of a bilaterian , including the three major tissue layers ( the endoderm , mesoderm and ectoderm familiar from high school biology texts ) , the presence of a gut with a mouth and anus , and paired coeloms ( body cavities ) surrounding the gut 这些微化石的大小为100 ~ 200微米,相当于几根头发的宽度, ?们看起来出奇复杂,而且简直就像两侧对称动物的教科书般,展示了各种特徵:包括三个主要的组织层(内胚层、中胚层及外胚层,都是中学生物课本中熟悉的名词) ,前后连接口部与肛门的肠腔,肠腔外还围绕著成对的体腔。
