将疏水性的PLLA掺合入基因转运载体后，能增强递药系统的与细胞的相互作用和组织渗透性。

Hydrophobic PLLA that is incorporated into the gene delivery vector is believed to enhance the cell interactions and tissue permeability of the delivery system.

除了帮助研究干细胞基因遗传，这种技术可以用来研究任何类型的细胞之间的相互作用。

In addition to helping with studies of stem cell reprogramming, this technique could be used to study interactions between any types of cells.

但是，细胞分化并非单一因素作用的结果，而是基因、细胞质及细胞外环境作用系统相互作用与反作用的结果。

The cell differentiation is not the result of the action of a single factor but of the interaction and counteraction of the action system among the gene, cytoplasm and extracellular environment.

It does that through a complex set of sort of cellular interactions, and it turns out also gene rearrangements if you go further to study that.

而这此过程中,发生了一系列复杂的细胞间的相互作用,也会涉及到基因重排,如果你们深入学习的话就会学到
