World's first lab-grown oesophagus implanted — hope for children born with rare condition

Scientists at Great Ormond Street Hospital and UCL engineered a functional lab-grown oesophagus using the patient's own cells — no immunosuppression needed. The results offer hope to children born with missing food pipes.

World's first lab-grown oesophagus

Researchers at Great Ormond Street Hospital (GOSH) and University College London have successfully engineered a functional lab-grown oesophagus and shown it can fully replace a missing section of the food pipe in a living, growing animal — without immunosuppression drugs.

How does it work?

A donor oesophagus is stripped of all cells, leaving a scaffold. The patient's own cells are then seeded onto the scaffold before implantation. After six months, the tissue had grown its own nerves, blood vessels, and muscle capable of normal swallowing.

Why does it matter?

About 18 babies per year in the UK are born with long-gap oesophageal atresia — a condition where part of the food pipe is simply missing. Current treatment involves years of painful surgeries. This breakthrough opens a path toward a definitive, personalised repair.
