Use of decellularized tracheas for airways engineering
2016
Background/Objective: Tracheal stenosis produces serious dyspnea. In some cases, a defective correction or timely intervention can lead to the death of the patient. The Hospital Clinico Universitario de Valencia is a reference hospital for the treatment of patients with airway problems exhibiting complex tracheal stenosis. Surgery is limited to a maximum length of 6-7 cm and it is not exempt of mortality (3-5%). In this study we have study the useful of decellularized porcine tracheas to be used in airway regenerative medicine. Methods: Three porcine tracheas were cut in 3 cm rings and exposed to SDS 2% for up to four weeks. Cell content was evaluated by fluorescence microscopy (DAPI) weekl…
Optimization of a decellularized protocol of porcine tracheas. Long-term effects of cryopreservation. A histological study
2021
[EN] Objective: The aim of this study was to optimize a decellularization protocol in the trachea of Sus scrofa domestica (pig) as well as to study the effects of long-term cryopreservation on the extracellular matrix of decellularized tracheas. Methods: Porcine tracheas were decellularized using Triton X-100, SDC, and SDS alone or in combination. The effect of these detergents on the extracellular matrix characteristics of decellularized porcine tracheas was evaluated at the histological, biomechanical, and biocompatibility level. Morphometric approaches were used to estimate the effect of detergents on the collagen and elastic fibers content as well as on the removal of chondrocytes from …
