Evaluation of the Regeneration Capacity of Satellite Cells From the Quadriceps Compared to That of the Diaphragm

During surgery for a benign or malignant tumor of the liver a quadriceps microbiopsy will be performed. A 1 cm incision of the skin and fat planes will be made using a scalpel until contact with the quadriceps aponeurosis. The biopsy needle will be inserted superficially into the muscular part allowing, through a suction system, a micro biopsy of the quadriceps of approximately 25 mg.
