title: Alpha(1)-adrenoceptors (alpha(1)-AR) and vascular smooth muscle cell growth.
abstract: BACKGROUND
  Smooth muscle cells in vascular tissue, like tissue within the urogenital sinus, undergo growth and proliferation.
  
  
  METHODS
  This review attempts to compare and contrast the mechanisms and controlling factors involved in prostatic and vascular tissue. There is a particular focus on the role of catecholamines and alpha-adrenoceptors (alpha-ARs), and on the effects of alpha(1)-AR antagonists (blockers) on cellular dynamics. RESULTS AND CONCLUSIONS The situation in vascular tissue appears analagous to that in prostatic tissue. Certain AR-antagonists, in addition to altering smooth muscle contraction, may have other actions on cellular dynamics.
