Since the cells of the immune system are derived from stem cells in the bone marrow , these patients go on to develop what is known as chimeric immunity , which blends elements from the immune systems of both the donor and the recipient .
因为免疫细胞源于骨髓干细胞,这些病人产生了一种同时具有捐献者和接受者免疫系统成分的二元免疫。
We also investigated the mechanism in regulating the surface targeting of these chimeric proteins , and found that the transmembrane domain may play a role in determining the final destination of the chimeric proteins .
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 .
