阴囊内移植脐血单个核细胞对老年小鼠机能的影响

The Effects of Cord Blood Mononuclear Cells Xenotransplantation in Scrotum on Old Mouse Body Functions

为明确阴囊内异种移植脐血单个核细胞对老年小鼠机能的影响,通过观察移植细胞的存活、作用,明确阴囊内移植的脐血单个核细胞不仅可以在小鼠体内存活,且无明显的副作用,还可以显著提高雄性老年小鼠的30 min内交配次数(P=0.018),但其不能提高老年小鼠的存活时间以及心脏每搏量(皆P>0.05).

In order to identify the effects of cord blood mononuclear cells xenotransplantation in scrotum upon old mouse body functions,the transplanted cells＇ survival and role were observed. The data suggests that the cord blood mononuclear cells transplanted in scrotum can survive with no obvious side effects. They can significantly improve the mating times in 30 minutes of old male mouse（ P = 0. 018）,but fail to change the survival time and cardiac stroke volume of old mouse（ all P 〉 0. 05）.
