| Abstract: | This study sought to better understand the effects of human fetal liver cells(FLC) on immunity. FLC were injected into BALB/c mice intraperitoneally. The design included four groups: negative control and three dose (125 x 10(5), 25 x 10(5), 5 x 10(5) FLC/day) groups. The results showed that FLC increased the thymus visceral coefficient, numbers of T-lymphocytes(TLC) and lymphocytes(LC) in blood, total number of spleen cells, the number of plaque forming cells(PFC) of spleen, the rate(%) of transformation and stimulus index of TLC of spleen, and the function of macrophages. FLC also effected the function of natural killer cells(NK cells) of BALB/c mice. The findings suggest that human FLC can strengthen the nonspecific immunity, humoral immunity and cellular immunity in mice. In this study, however, no effect of FLC on spleen visceral coefficient was noticed, and no sign of delayed type allergy was observed. |
