Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...
Researchers have reported growing hearts containing human cells in pig embryos for the first time. The embryos survived for 21 days, and in that time their tiny hearts started beating. The findings ...
A recent study in Nature Cell Biology identified guinea pigs as promising small animals to model preimplantation development, a critical step in human embryogenesis. Stem cells provide opportunities ...
In a Maryland operating room one day in November 2025, doctors made medical history by transplanting a genetically modified pig kidney into a living patient. The kidney had been engineered to mimic ...
Chinese researchers are preparing the details for the publication of another scientific milestone, the creation of a chimera with a human heart and a kidney developed from human stem cells in pig ...
Human embryo models can help researchers study early human development and infertility without relying solely on human ...
The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...
Putting pig organs in people is OK in the US, but growing human organs in pigs is not – why is that?
While research on human-pig chimeras is on an indefinite pause, xenotransplantation is moving ahead. wildpixel/iStock via Getty Images Plus In a New York operating room one day in October 2025, ...
