Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time — up to 20 days. The research, despite its ethical concerns, has the potential to provide new insights into developmental biology and evolution. It also has implications …
UT Southwestern led research published in Cell Stem Cell reports deriving a new intermediate embryonic stem cell type from multiple species that can contribute to chimera and create precursors to sperm and eggs in culture dishes. Findings could lead to a host of advantages in basic biology, regenerative medicine, and reproductive technology. Cells in early …
Chris Long of Reno, Nevada is currently in remission from acute myeloid leukemia. Just three months after undergoing bone marrow transplant operation it was revealed that the DNA in his blood had changed. Four years after his bone marrow transplant operation it was discovered that parts of his tongue, cheeks and lips all contained his …
Scientists in China have reported the World’s first full term pig-monkey chimera, two piglets were born live but died within a week, which is published in the journal Protein & Cell. The piglets looked normal but a small proportion of their cells between 1 in 1000 and 1 in 10,000, were derived from cynomolgus monkeys. …
