uniparental

uniparental inheritance that prevents pollen transmission of foreign dna;

母系遗传方式可防止基因扩散；

this unambiguously proves that the transplanted uniparental cells could produce hematopoietic stem cells.

这毫无疑问的证明了移植单系干细胞可以生成造血干细胞。

maternal inheritance: a type of uniparental inheritance in which all progeny have the genotype and phenotype of the female parent.

母性影响：由核基因的产物积累在卵细胞中的所引起的一种遗传现象。

the researchers took a two-step approach: first they injected uniparental es cells into wild-type blastocyst to generate chimeric animals;

研究人员采取了两步骤的方法：首先，他们将单系胚胎干细胞注入野生型的胚细胞培育嵌合体动物；

one issue in using uniparental es cells for tissue transplants is their durability and safety.

使用单系胚胎干细胞进行组织移植中的问题便是其耐用性和安全性。
