Five people have gone on trial in China for illegal organ trading and intentional injury after a student sold his kidney to buy an iPad and iPhone.
The defendants include the surgeon who removed the kidney from the 17-year-old in the central province of Hunan.
They face up to 10 years in prison if found guilty, according to the state-run Xinhua news agency.
The teenager, who suffered renal failure after the transplant, was said to be too sick to attend the hearing.
The student, identified only as Wang, was recruited in an online chat room, according to prosecutors.
They accused one of the defendants, He Wei, of arranging the illegal kidney transplant last April in order to pay his gambling debts.
The group is said to have received around $35,000 (£22,000) for the transplant, while the student was reportedly given about $3,000 for his kidney.
He nearly died after suffering renal failure following the operation and is said to still be in poor health.
'Priced beyond reach'
Mr He denied the charges, telling judges on that the teenager had been willing to undergo the surgery.
Four others accused of having a minor involvement in the case also face fines.
The case was discovered when the student's mother questioned him about how he obtained the money to buy his new gadgets.
He eventually admitted to selling his kidney.
