MSCs block initiation of complement cascade in lupus mice. (a) Immunofluorescent staining of C1q, factor P (FP), and immunohistochemical staining of MBL in a representative kidney section from three groups (n = 4–6 per group). Scale bar = 10 μm. (b-c) The grade of fluorescence intensity of C1q and FP in glomeruli from three groups (n = 4–6 per group). (d) The mean optical density of MBL deposition in glomeruli of B6.lpr mice (n = 4–6 per group). *p < 0.05; ns, not significant. Values are the mean ± SEM.
