JN: Pesquisadores da USP comemoram a primeira clonagem de um porco no Brasil
Summary
Researchers at the University of São Paulo (USP) have successfully cloned the first pig in Brazil, weighing two and a half kilograms. This achievement is part of a broader project aimed at addressing the organ transplant needs of approximately 48,000 Brazilians who require organ transplants.
The project focuses on xenotransplantation, which involves transferring organs from one species to another. Researchers have made significant advancements by integrating human genes into pig organs to enhance compatibility and reduce the risk of rejection.
Despite the success in cloning, challenges remain in making organ transplants a routine part of medical practice. The cloning process has a low efficiency rate of only 1 to 5 percent, which raises concerns about the scalability of producing sufficient organs for transplantation.
Future steps include cloning genetically modified embryos to initiate studies on organ performance in humans. The research aims to conduct preclinical and clinical studies to further understand the viability of these organs for transplantation.

The first cloned pig in Brazil weighs two and a half kilograms and is part of a research project aimed at addressing the organ transplant needs of 48,000 Brazilians. Researchers at the University of São Paulo have made significant advancements in xenotransplantation, integrating human genes into pig organs to improve compatibility.
- The first cloned pig in Brazil weighs two and a half kilograms and is part of a research project aimed at addressing the organ transplant needs of 48,000 Brazilians, conducted by the University of São Paulos research center focused on xenotransplantation
- Xenotransplantation, which involves transferring organs between species, is promising due to the similarity of pig organs to human organs, potentially alleviating the shortage of available human organs for transplant
- Research in xenotransplantation began in the 1960s but was halted due to acute rejection issues; recent advancements have enabled scientists to deactivate three genes responsible for this rejection
- The University of São Paulo team has integrated seven human genes into pig organs to improve compatibility, which is vital for increasing the success rates of future transplants
- After mastering cell modification techniques in 2022, researchers are now focused on cloning genetically modified pigs, a necessary step to produce enough modified animals for transplant needs
- The successful cloning of pigs marks a significant achievement, but challenges remain before xenotransplantation can be routinely practiced in medicine, necessitating further studies and clinical trials
