Trachea would open an investigation of Macchiarini's work and publications. Several bioengineering approaches have been tested to repair and replace the trachea, indicating extraordinary difficulties in a successful graft due. A 2016 article cited the tremendous difficulties of tracheal revascularization as a major challenge to any form of tracheal replacement. The study also notes that on top of the revascularization issue, there is no evidence that using bone-marrow stem-cells on a de-cellularized native trachea or synthetic scaffold will induce airway tissue regeneration, and such a method remains hypothetical.
