First Lab-Grown Oesophagus Successfully Transplanted

Scientists from Great Ormond Street Hospital (GOSH) and University College London have achieved a remarkable milestone in regenerative medicine: creating the first lab-grown oesophagus using tissue engineering and successfully transplanting it into minipigs. The results, published in Nature Biotechnology, showed that all eight animals survived the critical first 30 days.

By six months post-transplant, the grafts had developed functional muscle, nerves, and blood vessels — effectively becoming living, working organs. Perhaps most remarkably, the transplants did not require any immune suppression drugs, which are typically needed after organ transplants and carry significant long-term side effects.

“The results, published in Nature Biotechnology, showed that all eight animals survived the critical first 30 days.”

The engineered oesophagus was built using a decellularized scaffold — a biological framework stripped of its original cells — which was then repopulated with the recipient's own stem cells. This approach allows the body to recognize the transplant as its own tissue, eliminating the need for immunosuppressive therapy.

The breakthrough could have life-changing implications for children born with oesophageal atresia, a condition where the oesophagus does not form properly. Currently, these children undergo multiple complex surgeries with mixed results. The research team estimates that clinical trials in children could begin within five years.

Professor Paolo De Coppi, who led the research at GOSH, described the work as "a proof of concept that complex tubular organs can be engineered and transplanted successfully." The approach could eventually be adapted for other tubular organs, including the trachea and intestines.
