Growth performance in B-hIGF1R mice
Strain specific analysis of IGF1R gene expression in wild-type (WT) mice (+/+) and homozygous B-hIGF1R mice (H/H) by RT-PCR. Mouse Igf1r mRNA was detectable only in brain of WT mice (+/+). Human IGF1R mRNA was detectable only in homozygous B-hIGF1R mice (H/H) but not in WT mice (+/+).
Strain specific IGF1R expression analysis in homozygous B-hIGF1R mice by flow cytometry. Kidney was collected from wild-type mice (+/+) and homozygous B-hIGF1R mice, and analyzed by flow cytometry with anti-IGF1R antibody.IGF1R was detectable in wild-type mice and homozygous B-hIGF1R mice, as the antibody is crossly reactive with IGF1R in human and mice. Human IGF1R was exclusively detectable in homozygous B-hIGF1R but not in wild-type mice.
Strain specific IGF1R expression analysis in homozygous B-hIGF1R mice by flow cytometry. Brain was collected from wild-type mice (+/+) and homozygous B-hIGF1R mice, and analyzed by flow cytometry with anti-IGF1R antibody.IGF1R was detectable in wild-type mice and homozygous B-hIGF1R mice, as the antibody is crossly reactive with IGF1R in human and mice. Human IGF1R was exclusively detectable in homozygous B-hIGF1R but not in wild-type mice.
Strain specific IGF1R expression analysis in homozygous B-hIGF1R mice by flow cytometry. Lung was collected from wild-type mice (+/+) and homozygous B-hIGF1R mice, and analyzed by flow cytometry with anti-IGF1R antibody.IGF1R was detectable in wild-type mice and homozygous B-hIGF1R mice, as the antibody is crossly reactive with IGF1R in human and mice. Human IGF1R was exclusively detectable in homozygous B-hIGF1R but not in wild-type mice.
Immunofluorescence analysis of isolated brain microvessels from the wild-type mice and homozygous B-hIGF1R mice. Brain microvessels were collected from wild-type mice (+/+) and homozygous B-hIGF1R mice, and analyzed by immunofluorescence with anti-hIGF1R antibody. Human IGF1R was exclusively detectable in homozygous B-hIGF1R but not in wild-type mice.
Frequency of leukocyte subpopulations in spleen
Frequency of leukocyte subpopulations in spleen by flow cytometry. Splenocytes were isolated from wild-type C57BL/6 mice and homozygous B-hIGF1R mice (female, 8-week-old, n=3). A. Flow cytometry analysis of the splenocytes was performed to assess the frequency of leukocyte subpopulations. B. Frequency of T cell subpopulations. Frequencies of T cells, B cells, NK cells, DCs, granulocytes, monocytes, macrophages, CD4+ T cells, CD8+ T cells and Tregs in B-hIGF1R mice were similar to those in C57BL/6 mice, demonstrating that humanization of IGF1R does not change the frequency or distribution of these cell types in spleen. The frequency of leukocyte subpopulations in lymph nodes and blood of B-hIGF1R mice were also comparable to wild-type C57BL/6 mice (Data not shown). Values are expressed as mean ± SEM. Significance was determined by two-way ANOVA test. *P < 0.05, **P < 0.01, ***P < 0.001.
Anti-human IGF1R antibody Figitumumab binding assessment in B-hIGF1R mice. Kidney single cells were collected from wild-type C57BL/6 mice (+/+) and homozygous B-hIGF1R mice (H/H) (n=3, 6-old-week, female) and analyzed by flow cytometry. Anti-hIGF1R antibody Figitumumab (MCE, HY-P99197) can bind kidney single cells from B-hIGF1R mice at the concentration of 10ng/mL and 100ng/mL, but not in wild-type mice. And the increase of positive cells in total live cells was accompanied by the increase of Figitumumab concentration.

Comparison of body weights and tissues weights between WT and B-hIGF1R mice. The body weights of humanized mice were heavier than those of WT control mice regardless of gender(A). The weight of tissues such as the brain, spleen and kidney in female B-hIGF1R mice were heavier than those of WT female mice(C) while there is no difference in those three tissues’ weight between the male WT and B-hIGF1R mice(B). There is no difference in the weight of heart and lung between the male WT and B-hIGF1R mice regardless of gender. The weights of liver in B-hIGF1R mice were heavier than those of WT mice regardless of gender.
