Fig. 1From: Continuous dynamic identification of key genes and molecular signaling pathways of periosteum in guided bone self-generation in swine modelEstablishment of the animal models. A Schematic diagram of this procedure. B A segment of rib was removed, which resulted in a 3Â cm defect of rib. C The incised periosteum was sutured, creating a closed space. D The periostea were harvested after the swine were killedBack to article page
