Scientists in Israel have created synthetic rat embryos. While there are potential beneficial uses, this step may prove dangerous in the hands of scientists and leaders who do not fear or acknowledge the Creator. “Remarkably, we show that embryonic stem cells generate whole synthetic embryos, meaning this includes the placenta and yolk sac surrounding the embryo,” said Dr. Jacob Hanna, who headed the study. “We are truly excited about this work and its implications.” Researchers believe that this breakthrough could offer alternatives to animal experimentation and pave the way for new stem cell growth for human transplants. Skin cells could be potentially transformed into bone marrow stem cells, for example, to help treat patients suffering from leukemia.
Synthetic embryos failed to develop further when they were implanted into female mice. Human experimentation is purely hypothetical at this stage, although Hanna is optimistic about prospects for future research. Other researchers are more uncertain about the practical and ethical prospects of future experimentation. “Synthetic human embryos are not an immediate prospect. We know less about human embryos than mouse embryos and the inefficiency of the mouse synthetic embryos suggests that translating the findings to human requires further development,” Dr. James Briscoe, a researcher at London’s Francis Crick Institute, said to The Guardian. “Now is a good time to consider the best legal and ethical framework to regulate research and use of human synthetic embryos and to update the current regulations.”
