6. Chinese scientists report first live birth of chimeric monkey

A team of Chinese scientists has confirmed the first live birth of a monkey that contains a high proportion of cells derived from a monkey stem cell line, which paves the way for scientists to use chimeric primates to study human diseases.

The experiment demonstrated that the monkey stem cells, a type of cell able to develop into many different cell types, could efficiently contribute to placental tissues outside the embryo and germ cells.
