The route through which genes affect the over-all patterns of structure and function is their action upon and direction of ontogenesis, especially the prolonging and shortening of growth and differentiation periods; genetic variations between species should, therefore, find their immediate and most dramatic expressions in embryological and postnatal developmental histories.

基因影响全部的结构模式和功能的路线是他们行动和个体发生的方向，尤其发展和不同时期的延长和缩短；因此，种类间的基因变化应该找出他们直接和最引人注目的的表示在胚台学上和产后发展的历史。

METHODS:① MSCs were isolated from dog bone marrow by density gradient centrifugation, followed by in vitro adherent culture and ontogenesis culture.

①采用密度梯度离心法从犬骨髓中分离骨髓基质干细胞，体外贴壁培养扩增、成骨诱导培养。

Leaf reflectance spectra (400–800 nm) were measured to provide an in vivo non-destructive assessment of pigments in leaves during ontogenesis.

与其他发育阶段的叶片相比，幼叶的NPQ及Car/Chl比值较高。400-800 nm叶片反射光谱为活体无损伤检测叶片发育过程中其色素含量的变化提供了一种方法。

These findings are consistent with the previous knowledge that IGF-2 is mainly expressed during the embryonic phase, IGF-1 is mainly expressed during the postnatal period, which could promote cell proliferation and ontogenesis.

这与IGF-2主要在胚胎期发挥作用，而IGF-1则主要在动物个体出生后才发挥促进细胞增殖和个体发育功能的特点相符。
