We found a high level of cellular organization, with mesoderm cell movements correlating with some but not all ectoderm movements.

他们发现了一个高水平的细胞组织，与中胚层细胞运动有关，而不是与所有的外配层运动有关。

BACKGROUND: The basic fibroblast growth factor has the obvious promotion function of multiplication of the mesoderm and nerve ectoderm cells, and has the indirect ossification to the bone marrow-derived mesenchymal stem cells.

背景：碱性成纤维细胞生长因子对来源于中胚层和神经外胚层的细胞具有明显的促进增殖作用，对骨髓间充质干细胞具有间接的成骨作用。

In the present review, we focus on some of the recent advances and some key developmental events revealed in the fertilization process, including the role of the egg apparatus in guiding pollen tube orientation, sperm cell movement to their targeting cells, interaction between gametes, egg cell activation, and onset of embryogenesis and endosperm development.
