The results suggest that Smad4,one of the intracellular downstream molecules of TGF-β superfamily,and an inductive signal mediating epithelial-mesenchymal interaction,may regulate the differentiation of ameloblast and odontoblast cells,and modulate dentinogenesis and amelogenesis.

结论首次观察到Smad4信号分子在人牙胚发育过程中的表达，Smad4作为TGF-β超家族细胞内信号分子，可能参与上皮间充质的相互作用，同时也参与成釉细胞和成牙本质细胞的分化以及牙釉质和牙本质的形成。

In conclusion, we detailedly investigated the variation of membrane system (mainly plasmalemma, amyloplast envelope, ER) with the potassium permanganate fixative method, nucleus and organelles with routinely fixative method, and their functions with cytochemical method (localization of phosphatases and Ca〓).

综上所述，本文运用高锰酸钾固定法研究了膜系统（主要指质膜、淀粉质体被膜、内质网）的变化，运用常规固定制样研究了细胞核和细胞器的变化，采用细胞化学方法（Ca〓和磷酸水解酶的定位）探索了细胞器和细胞核的功能。

The artide focused on the cellule and molecule character of myocardic ischemia and ischemical reperfusion injury induced by strength training, the essential feature of strength training preconditioning and the signal transduction mechanism and the intra-cellular effector of myocardial preservation, proposing the research strategy, concrescencing the theory of contemporary strength training, clarifying some hot questions and important future directions on endogenous myocardial protection of strength training.

就力量运动引起相对心肌缺血及缺血再灌注损伤的细胞分子学特点、力量运动缺血预处理的基本特征及心肌保护作用的细胞信号转导机制与细胞内效应器及存在的问题进行阐述，提出研究策略。

In the third part, cultured H9C2 myocytes were randomly divided into two groups, the control group and 200mol/L DZ preconditioning group.

第三部分，培养的H9C2心肌细胞随机分成2组，即对照组和200mol/L DZ预处理组，分别富集两组细胞的磷酸化蛋白质，采用双向电泳和质谱技术，分离鉴定DZ预处理后心肌细胞内磷酸化蛋白的差异表达。

So if the old theory that we die with the heart cells we are born with is true, then people born before carbon 14 got into the food chain (nuclear testing didn't start until 1955) wouldn't have any carbon 14 in their heart cells.

如果根据心肌细胞不可再生理论，那么在C14进入食物链之前（1955年核试验开始前）出生的人心肌细胞内不会有C14，但事实并非如此，这些人的心肌细胞不仅含有C14，研究者还测定出了C14存在体内的时间。
