Abstract:
The mechanical stimulation can affect the biological function of lung cells, but little is known about the effects on biomechanical properties of lung fibroblasts. In this paper, the human lung fibroblasts (MRC-5) were subjected to cyclic stretch (5% and 10% elongation amplitude) by FX-4000 Tension System. The micropipette aspiration technique was used to investigate the viscoelasticity of MRC-5. The results: for 5% stretch group, the viscoelastic parameters of MRC-5 were significantly lower than static group at 72 h; for 10% stretch group, the viscoelastic parameters of MRC-5 were significant

Abstract:
COPD is a progressive chronic lung disease characterized by pulmonary inflammation. Several recent studies indicate aberrant expression of WNT ligands and Frizzled receptors in the disease. For example, WNT-5A/B ligand expression was recently found to be increased in lung fibroblasts of COPD patients. However, possible effects of WNT-5A and WNT-5B on inflammation have not been investigated yet. In this study, we assessed the regulation of inflammatory cytokine release in response to WNT-5A/B signaling in human lung fibroblasts.

Scatter factor/hepatocyte growth factor (SF/HGF) is a multifunctional cytokine produced by embryonic fibroblasts and other mesenchymal cells that affects the growth and/or the movement of certain epithelia. Here we report that expression of scatter factor activity by MRC 5 cells, a strain of normal human embryonic lung fibroblasts, is greatly reduced as a result of co-culture of these cells with SVK14, an SV40-transformed human keratinocyte cell line. Using a cDNA probe to the beta chain of human HGF, we have found that the fall in SF activity in MRC 5/SVK14 co-cultures is accompanied by the l
