Israeli scientists create model of human embryo without eggs or sperm

Posted by in category: biotech/medical

Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into the early stages of embryonic development.

The model resembles an embryo at day 14, when it acquires internal structures but before it lays down the foundations for body organs, according to the team at Israel’s Weizmann Institute of Science.

The Israeli team emphasised that they were a long way from being able to create an embryo from scratch.

“The question is, when does an embryo model become considered an embryo? When that happens, we know the regulations. At the moment we are really, really far off from that point,” said team leader Jacob Hanna.
