Then, just as with a cadaver trachea, it was seeded with stem cells and incubated in the growth medium, and within two days, the patient had his new airway. In Europe, an international team of surgeons and scientists has been transplanting stem cell-based tracheas since 2008. Post was not sent - check your email addresses! The transplant community is challenged to address the ongoing crisis in organ transplant access. Intrepid clinicians and researchers are using regenerative medicine techniques to help people whose ability to speak, sing, hear—or yes, kiss—has been impaired. Instead, bioengineers at the University College London developed an artificial laryngotracheal scaffold from plastic. All Rights Reserved.

Not many people know how organ transplantation work, and the number of people who know that there are alternatives to it, are even lower. Different organ xenotransplants result in different responses in clotting. An organ transplant is a surgical operation where a failing or damaged organ in the human body is removed and replaced with a new one. ENTtoday is a publication of The Triological Society.
