Detailed explanation-1: -Researchers at the Weizmann Institute in Israel have produced the first “synthetic embryos” in the world without the need for sperm, eggs, or fertilisation.
Detailed explanation-2: -The team, led by Professor Magdalena Zernicka-Goetz, developed the embryo model without eggs or sperm, and instead used stem cells – the body’s master cells, which can develop into almost any cell type in the body.
Detailed explanation-3: -Where do these embryos come from? The embryos being used in embryonic stem cell research come from eggs that were fertilized at in vitro fertilization clinics but never implanted in women’s uteruses. The stem cells are donated with informed consent from donors.
Detailed explanation-4: -Whereas Germany, Austria, Italy, Finland, Portugal and the Netherlands prohibit or severely restrict the use of embryonic stem cells, Greece, Sweden, Spain and the United Kingdom have created the legal basis to support this research. Belgium bans reproductive cloning but allows therapeutic cloning of embryos.
