And , the immune system does not stay chimeric forever .

此外，这种免疫系统并不永远是二元的。

The construction and characterization of chimeric plasmids psc33 , psc48 .

双抗性质粒psc33、psc48的构建及其特性研究。

Scientists have found they can create chimeric animals that have organs belonging to another species by injecting stem cells into the embryo of another species .

科学家们发现只需向动物胚胎中注射另一物种的干细胞，他们便能创造出一种拥有另一物种器官的嵌合体动物。

Chimeric cellswere scattered everywhere , including the sex cells . This means that , inprinciple , a marmoset can either father ( if male ) or give birth to ( if female ) a baby that is its niece or nephew rather than its son or daughter .

嵌合细胞在狨猴的体内到处散布，包括生殖细胞的散布.这就从理论上意味着，雄性狨猴会生养幼猴或雌性狨猴会生育幼猴，而此时的幼猴则不再是各自的儿子或女儿，而是侄女或侄子.

One technique , called chimeric antigen receptor ( car ) therapy , draws white blood cells out of a patient 's body , genetically modifies them in the laboratory to recognize and attack tumor cells , then injects them back into the patient .

一种称为嵌合抗原受体（car）治疗的技术，把白细胞从患者体中提取出来，在实验室中对它们的基因进行修饰，以使它们能识别和攻击肿瘤细胞后，再把它们注回到患者的体内。
