We studied the properties of a tissue-engineered trachea consisting of a polyethylene terephthalate scaffold populated with autologous bone marrow mononuclear cells. The tissue-engineered constructs were obtained before surgery, during the postoperative period, and during autopsy. Cytomorphological analysis during the postoperative period showed the presence of mesenchymal stem cells on the inner surface of the implant on day 3 after surgery and cells of the respiratory epithelium on day 10-14. In autopsy samples, single epithelial cells, endothelial cells, and basal cells were found. Biocompatibility of the tissue-engineered trachea with autologous mononuclear cells of the patient was demonstrated.
