In A First, Scientists Create Embryos Having Mix Of Human, Monkey Cells

In a first of its kind, scientists formed embryos consisting human and monkey cells. Aimed at growing transplanted organs, the scientists injected the embryos of macaque monkeys with human stem cells thereby studying it for 19 days. While laying stress on the behaviour of two interrelated cells, the research surprisingly showcased growth of several human cells in embryos. However, experts have raised ethical concerns in connection with experiment.
