The use of 0.1 and 0.05 % v/v dilutions (PP meshes with up to ∼2 % w/w of BAK) showed proliferative activity on fibroblast cells, indicating that these novel antimicrobial meshes show great promise for hernia repair due to their ability to prevent infections while inducing fibroblast proliferation. The gene discussed is BAK1; the disease is Hernia.
