The development has sparked a debate on the ethics of growing organisms in a lab.
Weizhi Ji, Kunming University of Science and Technologyof researchers confirms.
In the new study, the researchers, led by Prof Juan Carlos Izpisua Belmonte from the Salk Institute in the US, detail their experiments with cells from a long-tailed macaque and a human. They reveal that the cells can survive and even multiply when matched together.Despite the controversy surrounding such works, the researchers say their research may one day allow human organs to grow inside other animals, allowing for a new source of transplant organs.
"These results may help to better understand early human development and primate evolution and develop effective strategies to improve human chimerism in evolutionarily distant species," the authors wrote.The paper details how the scientists took human fetal cells and reprogrammed them to become stem cells. These were subsequently introduced into 132 embryos of long-tailed macaques, six days after fertilization.

Scientists Have Finally Solved a Crystal Shape ConundrumRice theorists have developed a method that can accurately predict the shapes of crystals that do not have symmetry. The shape of a crystal is determined by its inherent chemistry, which ultimately determines its final form from the most basic of details. However, the lack of symmetry in some cryst
