摘要

Abstract

<正> Objective: To investigate the relation between Shp-2 （a cytoplasmic tyrosine phosphotase） and matrix metalloproteinase-1 （MMP-1） in the migration of mouse embryo fibroblast cell. Methods: Shp-2 -/-embryo fibroblast was separated from Shp-2 knockout mouse on E10. 5

and Shp-2 cDNA was transfected into Shp-2 -/- cell. The cell migration was observed with the wound healing

the MMP-1 expression and secretion was analyzed by immunoblotting and immunoprecipitation. The activation of MMP-1 in the supernatant was detected with type I collagenase activity assay after the stimulation of IL-1α compared with E10. 5 mouse embryo fibroblast cell（Shp-2 +/+）. Results: There was obvious migration in Shp-2 +/+ cells and Shp-2 -/-R cells

but not in Shp-2 -/- cells. The shape of Shp-2 -/- cell was epithelial-like. The expression and secretion was increased in Shp-2 +/+ cells and Shp-2 -/-R cells

and it had not changed in Shp-2 -/- cell. The activation of MMP-1 was lower in Shp-2 -/- cells compared to the other cells. C
