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。 3. These congenital lesions arise from abnormal separation of the endoderm and neuroectoderm during embryogenesis这些先天性的异常是因
The formation of mesoderm following recombinations of presumptive ectoderm and endoderm from cleavage-stage frog embryos: K.E. Pierce and A.J. Brothers. Department of Zoology, University of California, Berkeley, CA 94720 USAdoi:10.1016/0045-6039(85)90109-5...
The efficient differentiation of hepatic endoderm cells (approximately 55%) together with the absence of neuroectoderm and mesoderm markers suggests the selective induction of endoderm differentiation. The co-expression of E-cahderin and alpha-fetoprotein (approximately 98%) suggests the important role ...
17、Mesenchymal stem cell cultured in vitro adheres to the wall and diplays the fibro-like phaenotype and differentiates to the cells of endoderm、mesoderm、ectoderm under certain condition. ─── 在体外培养时,细胞贴壁生长,呈成纤维样细胞表型,在一定条件下可分化内胚层、中胚层和外胚层细胞。 18、...

These cells are connected to the mesoderm by a long cytoplasmic process and it is suggested that they could be cells entering the endoderm from the middle layer, having accompanied the mesoderm cells through the primitive streak.Jennifer Wakely...
In contrast to the relatively mild defects observed in single mutants, loss of both bon and sur results in a severe phenotype characterized by absence of prechordal plate, cardiac mesoderm, endoderm and ventral neuroectoderm. Analysis of Nodal-regulated proteins reveals that Bon and Sur have both...
