Genetic Predisposition of Postoperative Adhesions Varies in Substrains of BALB/c Mice

Postoperative adhesions are a major clinical problem because of the associated infertility, chronic pain, bowel obstruction, and the associated costs. Variability in adhesion formation was suggested by clinical observations that apparently similar interventions can cause little to severe adhesions. This is supported by the presence of polymorphisms and genetic predisposition to develop adhesions in animal models and humans. We previously demonstrated differences in postoperative adhesions between different mouse strains. In this study, we aimed to investigate the variability in adhesion formation in inbred substrains of BALB/c mice. Since genetic differences in inbred substrains are minimal, they might be an opportunity to tackle the genetics of adhesion formation.
