neoplasm
• onset of palpable mammary tumor formation is slightly delayed and growth of the primary tumor is reduced compared to control heterozygous Tgfb1i1tm1.1Cet Tg(MMTV-PyVT)634Mul mice
• tumor stroma contains fewer cancer-associated fibroblasts and reduced extracellular matrix deposition
• isolated cancer-associated fibroblasts are defective in stress fiber organization and exhibit reduced contractility
• more than 2-fold reduction in the number of proliferating cells in mammary tumors
• mammary tumors exhibit fewer lung metastases than controls
