Quick Answer
The first 3D-printed bladder was implanted in a patient in 1999 by Anthony Atala.
The Full Story
In 1999 Dr Anthony Atala at Wake Forest University implanted a lab-grown bladder using a scaffold seeded with the patient's own cells — often cited as the first 3D-bioprinted organ implant. Since then, 3D bioprinting has advanced rapidly: in 2019 researchers in Israel printed a miniature heart from human tissue. Fully functional complex organs like kidneys and livers remain a major challenge, but simpler tissues, including ear cartilage and skin grafts, have been successfully printed and used clinically.
Key Facts
1.Atala's bladders used biodegradable scaffolds that dissolved as the patient's cells grew.
2.The 2019 mini-heart printed in Israel was about the size of a cherry.
3.Bioprinting uses bio-inks made from living cells and growth factors.
