Fig. 3From: Establishing a tree shrew model of systemic lupus erythematosus and cell transplantation treatmentELISA was used to detect changes in the tree shrew serum IgG and complement C3 levels at 1, 2, and 3 weeks after injection (n = 20) (*P < 0.01 compared with the other groups 3 weeks after injection). a Serum IgG levels of tree shrews injected with pristane and LPS increased most significantly 3 weeks after injection (*P < 0.01 compared with the other three groups, n = 20). b Complement C3 levels increased most significantly in the pristane and LPS group 3 weeks after injection (*P < 0.01 compared with the other three groups, n = 20).
