Cardiovascular and Renal Research

Research areas

  • Renal and cardiovascular regulation of salt and water balance and blood pressure in the normal condition, during development, and under pathomogical salt and water retaining conditions
  • Cardiac stem cells
  • Diabetes-associated vascular changes
  • Receptor pharmacology and Cellular mechano-electrical transduction

Available methodologies, techniques and facilities

  • Cell isolation and cell culture facilities for cell lines and primary cultures (juxtaglome-rular cells, vascular smooth muscle (renal, rat and human aortic), inner medullary collecting duct cells, mesangial cells, renin-producing AS4.1 cells, human aortic endothelial cells, rat cardiac myocytes and fibroblasts (neonatal and adult), and cardiac stem cells.
  • Conscious dog and rat setup with servo mechanisms controlling body contents of water and salt and blood pressure.
  • On line recordings of blood pressure in conscious unstressed mice
  • Electrophysiological recordings on single cells (tight seal whole cell recordings): membrane potential (current clamp), current-voltage relationship, single channel (voltage clamp) and membrane capacitance.
