Foreign media: A team of Chinese scientists has successfully cultivated a beating heart structure with human cells in a pig embryo, and reported that the heart structure continued to beat for 21 days without external assistance.
Previously, the team had successfully cultivated human kidneys in pigs for 28 days. According to a report in the journal Nature, researchers reprogrammed human stem cells by introducing anti-apoptosis genes to improve their survival rate in pigs. These human stem cells were then implanted into pig embryos at an early blastocyst stage and transferred into surrogate sows.
This breakthrough research provides new possibilities for xenogeneic organ regeneration and future clinical transplantation.
