Let's take a look at Luke Massella’s case
Luke was one of the first people in the world who received bioprinted organs from his cells. The procedure was completed by Dr.Anthony Atala at Boston Children’s Hospital. He took a small piece of Luke’s bladder and grow a new bladder via bioprinter for 2 months. Patients usually wait years for a suitable organ, so just 2 months of waiting is quite a short time. Then in a 14-hour surgical procedure, he replaced the defective bladder with the new one. Since the new bladder was made from the patient's cells, there were no problems with organ rejection, as is usually the case with organ transplants from other patients.
After receiving his replacement bladder at the age of 10, Luke’s treatment allowed him to live a normal life.
