An Intact Kidney Slice Model to Investigate Vasa Recta Properties and Function in situ [PDF]

, 2012
Background: Medullary blood flow is via vasa recta capillaries, which possess contractile pericytes. In vitro studies using isolated descending vasa recta show that pericytes can constrict/dilate descending vasa recta when vasoactive substances are ...
