Quote:Scientists grow whole model of human embryo, without sperm or egg
Quote:Scientists have grown an entity that closely resembles an early human embryo, without using sperm, eggs or a womb.
The Weizmann Institute team say their "embryo model", made using stem cells, looks like a textbook example of a real 14-day-old embryo.
It even released hormones that turned a pregnancy test positive in the lab.
The ambition for embryo models is to provide an ethical way of understanding the earliest moments of our lives.
The first weeks after a sperm fertilises an egg is a period of dramatic change - from a collection of indistinct cells to something that eventually becomes recognisable on a baby scan.
