Demonstration of a basic fibroblast growth factor-like molecule in mouse hepatic endothelial cells.

Abstract:

:We have investigated whether isolated mouse hepatic sinusoidal endothelial cells (HSEC) synthesized basic FGF. HSEC lysate was fractionated by heparin-Sepharose chromatography. A peak of mitogenic activity for Balb/c 3T3 fibroblasts was eluted with 3M NaCl. Several arguments suggested that the mitogenic factor was related to bFGF: a) its affinity for heparin; b) the loss of its mitogenic activity by heating at 65 degrees C, which was prevented in the presence of heparin; c) the abolition of its mitogenic activity in the presence of protamine sulfate; d) finally, its mitogenic effect was reduced in the presence of antibody to bFGF. These data demonstrate the presence of a bFGF-like molecule in HSEC. This molecule could be involved in the regulation of the neighboring Ito cell proliferation.
