Embryo Model

Whole Embryo Model has grown up by The Weizmann Institute Scientists that closely resembles an early human embryo, without using sperm, eggs or a womb.
The model represents a 14-day-old human embryo using reprogrammed stem cells
The model even released hormones that turned a pregnancy test positive in the lab
This achievement offers a tool to study early embryonic development ethically and how miscarriage and birth defects happen
The process involves reprogramming stem cells to become four types of cells found in early human embryos
Scientists hope that it will eventually help them create the body's organs and understand inherited or genetic diseases
However, the researchers stated that it would be illegal and actually impossible to achieve a safe pregnancy using these models yet
