PURPOSE Platelet-derived growth factor (PDGF) and its receptors could contribute to the development of proliferative retinal membranes, because PDGF is angiogenic and is both mitogenic and chemotactic for retinal pigment epithelial (RPE) and glial cells, components of membranes. The authors sought to determine whether PDGF ligands and their receptors were… (More)
Two important signaling pathways in liver fibrosis are the PDGF- and TGFβ pathway and compounds inhibiting these pathways are currently developed as antifibrotic drugs. Testing antifibrotic drugs requires large numbers of animal experiments with high discomfort. Therefore, a method to study these drugs ex vivo was developed using precision-cut liver slices… (More)
PURPOSE Integrins are cell surface adhesion molecules that serve as receptors for extracellular matrix components or for other cells. Integrins help regulate processes such as cell proliferation, migration, and differentiation. These processes are thought to have fundamental roles in the pathogenesis of proliferative retinal membranes in diseases such as… (More)
A non-rotating, chronically implanted microdrive for small animals is described. The unit can be used for recording both slow wave and single unit activity.
