Study on PDGF receptor beta pathway in glomerular formation in neonate mice.

The assembly of vascular endothelial cells (ECs) and smooth muscle cells is a critical event in the development of the cardiovascular system. Although the role of ECs in this event has been studied intensively, the cross-talk between the two cell components remains poorly understood. In this study, we blocked platelet-derived growth factor receptor (PDGFR) pathways in mice by antagonistic rat monoclonal antibody APB5 against murine PDGFR-beta and examined glomerular capillary formation.
