The abdominal wall is comprised of muscles and connective tissue. A hernia occurs when there is a tear in the wall, allowing what is behind the wall to push through.
When there is damage to the cells, tissue must be regenerated. This regeneration depends on a series of physiological events.
The first stage of this process is the inflammatory phase. After many other cells migrate to the damaged site, the differentiated cells produce and deposit new extracellular matrix.
Studies, such as the one published last year by LifeCell Corporation in New Jersey, have used porcine dermal tissue to make a biocompatible mesh to repair multiple damaged tissues, while minimizing infections or adhesions.
