Fluid shear stress regulates the expression of TGF-beta1 and its signaling molecules in mouse embryo mesenchymal progenitor cells.

ABSTRACT:

Background

Recently we reported that fluid shear stress promotes endothelial cell differentiation from a mouse embryo mesenchymal progenitor cell line C3H10T1/2. However, it is not clear whether the transforming growth factor-beta 1 (TGF-beta1) system is associated with shear-induced endothelial differentiation. The purpose of this study was to determine the effect of shear stress on the expression of TGF-beta1 and its signaling molecules in C3H10T1/2 cells.

Methods

Murine C3H10T1/2 cells were incubated on collagen Type 1-coated dishes, and subjected to a steady fluid shear stress of 15 dyn/cm(2) for 6, 12, and 24 h. The mRNA levels for TGF-beta1, TGF-beta receptors (TGF-beta R), and Smad molecules were determined with real-time PCR analysis and normalized to glyceraldehyde-
