This pushing-in of cells marks the start of gastrulation .
细胞的这种向里推进标志着原肠胚形成的开始。
Twisted gastrulation homolog 1 ( drosophila )
扭曲原肠胚形成同源物1(果蝇)
Using an optimized imaging approach and quantitative methods , we analyzed the trajectories of hundreds of ectodermal cells and internalized mesodermal cells within drosophila embryos over 2 hours during gastrulation .
利用优化的成像方法和定量手段,研究人员分析了果蝇胚胎形成2小时后的外胚层和中胚层细胞运动轨迹。
The collaborative program in developmental biology is primarily dedicated to research and education in developmental biology including amphibian gastrulation , molecular control of hematopoiesis , lymphocyte lineage commitment and cell development , hematopoietic stem cells , lymphocyte development , cell enlargement and cell differentiation , vertebrate embryogenesis , developmental neurobiology .
