Objective To study the effect of the activated mutant SHP-2 on murine angiogenesis and its role in tumorigenesis. Methods Heterozygous SHP-2 D61G mutant knock in and wild type C57BL/6 mice were used. The Matrigel containing FGF, VEGF was injected in the local subcutaneous of mouse to induced the angiogenesis. The method of Colorimetric Technique was used to detect the content of Hemoglobin (HB) in the matrigel to represent vascular density. The mouse peripheral blood HB concentration was assayed by the Blood Count Instrument for balance of HB level in matrigel. Then the matrigel was fixed and section was made and done Immunohistochemistry (IHC) for CD31 positive endothelial cell analysis. Finally the Transwell system was used to detect the migrating ability of mouse embryonic fibroblasts (MEFs). Result The HB level was higher in matrigel from SHP-2 D61G mutant mice than that from WT control mice. CD31 positive cells were increased dramatically in matrigel from SHP-2 mutant mouse than that from WT control group(P<0.01). The migration of SHP-2 D61G mutant MEFs were much more than WT MEFs (P<0.01). Conclusion Leukemia related mutant SHP-2 may promote mouse angiogenesis and the promotion effect may be related with the enhanced migrated ability of SHP-2 mutant cell.
