Scientists create model embryos in lab, raising major ethical questions

Advertisement Australian researchers have created “model” human embryos from the skin cells of an adult’s arm, in a world-first scientific breakthrough that raises significant ethical questions. The model embryos, created in a laboratory by researchers at Melbourne’s Monash University, do not use egg or sperm, but ordinary cells that are reprogrammed to replicate the first few days of human life.

However, they are not identical to natural embryos, lacking several key features and containing cells not normally seen.

Human skin cells altered to mimic early stage of embryo development

Monash University Living structures that model early human embryonic development have been generated entirely from cells in the skin. The models mean it should be possible to study infertility, early miscarriage and early embryonic development without the controversial use of real human embryos – although the models may raise ethical issues of their own. Previously, the only means of studying the early development of human embryos was via blastocysts obtained from IVF procedures. Blastocysts are a ball-like early stage of embryonic development that is formed five days after fertilisation occurs and can go on to form embryos. But their use in science is controversial because of their potential to grow into a living human individual.
