Lab-Grown Human Embryos Offer New Research Hope

Handout photo shows a stem-cell derived human embryo model showing blue cells (embryo), yellow cells (yolk sac) and pink cells (placenta). 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 researchers, led by Palestinian scientist Jacob Hanna at the Weizmann Institute in Israel, harnessed the power of embryonic stem cells, which can become any kind of cell. They produced embryo models up to 14 days old, which is the legal limit for human embryo lab research in many countries, and the point at which organs like the brain begin to develop. The researchers say their work differs from those of other teams because it uses chemic

    Israeli researchers grow human embryo models from stem cells to study human embryonic development

    STORY: Israeli researchers grow human embryo models from stem cells to study human embryonic development DATELINE: Sept. 9, 2023 LENGTH: 00:02:45 LOCATION: Jerusalem CATEGORY: TECHNOLOGY SHOTLIST: 1. various of researchers working at a lab of the Weizmann Institute of Science STORYLINE: Stem cell researchers created artificial models of human embryos and successfully grew them outside the womb up to day 14, the Weizmann Institute of Science (WIS) in central Israel said in a statement on Wednesday. In a new study published in the journal Science, the researchers created artificial stem cell embryo models that accurately mimic all the essential features and components of this developmental stage, including the placenta, yolk sac, chorionic sac, and assorted external tissues essential for facilitating dynamic and healthy growth. Due to their genuine complexity, the human embryo models created by the WIS team could offer an unprecedented opportunity to gain fresh insights into the beginnings of embryos, acco
