A cloned pig developed as part of a University of São Paulo (USP) research project aimed at making animal organs suitable for human transplantation has died, according to Folha de S.Paulo. The animal was euthanized after reaching sexual maturity, as reported by the Brazilian outlet and echoed by band.com.br and Diário do Centro do Mundo.
The procedure took place at a USP facility, with the decision tied to the pig's developmental stage. Folha de S.Paulo reports that the euthanasia was carried out in line with the project's protocols, though the specific reasons for the timing were not detailed in the available coverage.
The pig was part of a broader scientific effort to genetically modify animals so their organs could potentially be used in human transplants, a field known as xenotransplantation. According to the reports, this particular animal was the first cloned pig in the USP project intended for that purpose. Its death marks a setback in the research timeline, though the project itself is ongoing.
The news was first published on Saturday, August 8, 2026, and has since been picked up by multiple Brazilian news organizations. The exact cause of death beyond the euthanasia, as well as any follow-up plans by the research team, has not been disclosed in the material reviewed.
What to watch next: whether USP releases further details on the project's next steps or any adjustments to its breeding and study protocols following this loss.
