Background  Shear stress forces acting on liver sinusoidal endothelial cells following resection have been noted as a possible trigger in the early stages of hepatic regeneration. Thus, the morphology and gene expression of endothelial cells following partial hepatectomy or shear stress  in vitro  was studied.    Results  Following partial hepatectomy blood flow-to-liver mass ratio reached maximal values 24 hrs post resection. Concomitantly, large fenestrae (gaps) were noted. Exposure of liver sinusoidal endothelial cells,  in vitro , to physiological laminar shear stress forces was associated with translocation of vascular endothelial cell growth factor receptor-2 (VEGFR-2) and neuropilin-1 from perinuclear and faint cytoplasmic distribution to plasma membrane and cytoskeletal localization. Under these conditions, VEGFR-2 co-stains with VE-cadherin. Unlike VEGFR-2, the nuclear localization of VEGFR-1 was not affected by shear stress. Quantification of the above receptors showed a significant increase in VEGFR-1, VEGFR-2 and neuropilin-1 mRNA following shear stress.    Conclusion  Our data suggest a possible relation between elevated blood flow associated with partial hepatectomy and the early events occurring thereby.
