Sarah Gould's (currently at Novozymes) paper entitled "The role of valvular endothelial cell paracrine signaling and matrix elasticity on valvular interstitial cell activation" published in Biomaterials

January 28, 2014

Sarah Gould's paper entitled "The role of valvular endothelial cell paracrine signaling and matrix elasticity on valvular interstitial cell activation" demonstrates the essence of the interplay between VICs and VECs in maintaining a healthy valve phenotype. She further investigates the role of nitric oxide as a paracrine signaling molecule using a L-NAME, a soluble NO analog.
