Supplementary Figure 1
SPARC is not expressed by EL4 tumor cells in vivo. SPARC in EL4 tumors grown in wild-type (+/+) mice was restricted to host cells whereas SPARC was not detectable in EL4 tumors grown in SPARC-null (/) mice. Bars equals 50 μm.
Supplementary Figure 2
Macrophage infiltration of tumors is impaired in mice lacking SPARC. Representative immunohistochemical staining with Mac3, a marker of mature macrophages, showing the extent of infiltration into the LLC tumors grown in wild-type (+/+) or SPARC-null (/) mice. Bars equals 50 μm.
Supplementary Figure 3
Cell proliferation and apoptosis in LLC tumors are not affected in mice lacking SPARC. Representative immunohistochemical staining with anti-phosphorylated histone H3 (p-H3) and antiactive caspase 3 shows no difference in the number of positive cells in LLC tumors grown in wild-type (+/+) or SPARC-null (/) mice. Bars equals 50 μm.
