  • These clinical results provide evidence that a tissue-engineering strategy including decellularisation of a [deceased donor] human trachea, autologous epithelial and stem-cell culture and differentiation, and cell-scaffold seeding with a bioreactor is safe and promising," the group wrote. (medpagetoday.com)
  • The initial case of a tissue-engineered trachea involved a 7-cm section of deceased donor tissue repeatedly washed in a solution to remove all the cells, leaving behind a scaffold on which the recipient's epithelial and stem cells were seeded. (medpagetoday.com)

  • An investigation has found the thoracic surgeon who transplanted artificial tracheae into patients not guilty of overhyping his research. (the-scientist.com)
  • The trachea begins level with the sixth cervical vertebra and the carina is found at the level of the fifth thoracic vertebra (T5), opposite the sternal angle and can be positioned up to two vertebrae lower or higher, depending on breathing. (wikipedia.org)
  • This occurs at the lower end of the trachea (usually at the level of the 4th thoracic vertebra, which is in line with the sternal angle, but may raise or descend up to two vertebrae higher or lower with breathing). (wikipedia.org)
  • divides
  • In the fourth week of development of the human embryo as the respiratory bud grows, the trachea separates from the foregut through the formation of tracheoesophageal ridges which fuse to form the tracheoesophageal septum and this separates the future trachea from the oesophagus and divides the foregut tube into the laryngotracheal tube. (wikipedia.org)
  • Widening and distortion of the carina is a serious sign because it usually indicates carcinoma of the lymph nodes around the region where the trachea divides. (wikipedia.org)
  • airways
  • In the case where no blood is visible in the trachea, EIPH in the small airways may still be present and can be confirmed by a bronchoalveolar lavage. (wikipedia.org)
  • artificial

  • adult
  • In the child the trachea is smaller, more deeply placed, and more movable than in the adult. (bio-medicine.org)
  • The trachea of an adult has an inner diameter of about 1.5 to 2 centimetres (0.6 to 0.8 in) and a length of about 10 to 11 centimetres (4 in. (wikipedia.org)
  • The trachea is no more than 4mm diameter during the first year of life, expanding to its adult diameter by late childhood. (wikipedia.org)
  • subglottic
  • Lung function and volumes and diffusion capacity remained normal until 44 months, when worsening cough and wheezing led to discovery of a sub-occlusive stenosis at the site of a subglottic resection done 4 years prior to the trachea transplant. (medpagetoday.com)
