The vertebrate axial skeleton (vertebral column and ribs) is derived from embryonic structures called somites. Mechanisms of somite formation and patterning are largely conserved along the length of the body axis, but segments acquire different morphologies in part through the action of Hox transcription factors. Although Hox genes' roles in axial skeletal(More)
OBJECTIVE To design and evaluate an ex vivo model of tracheomalacia with and without a three-dimensional (3D)-printed external tracheal splint. STUDY DESIGN Prospective, ex vivo animal trial. METHODS Three groups of ex vivo porcine tracheas were used: 1) control (unmanipulated trachea), 2) tracheomalacia (tracheal rings partially incised and crushed),(More)
