Scientists have grown aย perfectly compatibleย ear in a labย and graftedย it onto a patient, in what they said wasย aย world firstย in regenerative medicine.
The groundbreaking technique saw them use the patientโs own ear cartilageย cells to form a new one.
Five children suffering from aย conditionย known as microtia,ย in which the externalย ear is underdeveloped, haveย undergone the experimental surgery.
