The Massachusetts man who received the world's first pig kidney transplant has died.

Massachusetts General Hospital announced the news Saturday, two months after the procedure. Richard Slayman of Weymouth made history after receiving the surgery.

The pig kidney had undergone genetic editing and the transplant operation took a team of surgeons four hours to complete, according to Mass General.

The pig kidney was provided by eGenesis of Cambridge, Mass., from a pig donor that was genetically-edited using CRISPR-Cas9 technology to remove harmful pig genes and add certain human genes to improve its compatibility with humans," the hospital said in news release issued at the time of the transplant in March.

The hospital said it has no indication Slayman's death was the result of the transplant.

A statement from his family thanked his doctors for giving them seven more weeks with him.
