Equine hyperelastosis cutis (HC or HERDA), a connective tissue disorder in American Quarter Horses, results in hyperelastic skin with poor wound healing. Similar conditions are found in many species and all forms display decreased skin tensile strength. Fibroblasts produce collagen and elastin fibers, forming networks, providing the dermis with strength, and elasticity. This study aims to carry out a 3-part evaluation between horse skin fibroblast (cells from horses affected with HERDA, cells from horses that are carriers of HERDA (recessive HERDA gene), and cells from horses that are normal (neither affected or carriers of HERDA); Studies include: 1. Cell proliferation assay 2. Apoptosis analysis of fibroblasts 3. Mechanobiology of stretched fibroblast. Studies have shown cellular deformation to have an overall effect on mechanical properties of healthy and unhealthy tissues. This investigation provides a micromechanical evaluation of HC/HERDA in an effort to quantify the cellular level differences between each condition.
