Scientists create mice chimeras with an unprecedented amount of human cells: study

The video discusses a study on human-mice chimeras, where human stem cells are used to create chimeras by suppressing the M Tor protein, allowing the cells to grow in mice embryos. As the embryos mature, human cells are found in tissues like the heart, liver, and bone marrow. The technology could help in organ generation without ethical concerns, as no human material is found in reproductive cells.
