Israeli Scientists Create Human Embryo Model without Using Eggs or Sperm - Industry Tap

Israeli scientists create lab-made human embryo model from stem cell, paving way to research in early stages of embryo.

Transplant organs are scarce. Could growing ones with human cells in pigs alleviate the shortage?

Scientists in Israel have grown a model of an early human embryo without using a human egg, sperm, or womb.

Dublin, Sept. 08, 2023 (GLOBE NEWSWIRE) -- The

Scientists at the Weizmann Institute of Science in Israel have successfully grown human embryo-like structures in a lab without using sperm, eggs, or a womb. The researchers used pluripotent stem cells to create synthetic embryo models that closely mimic the development of a real human embryo. These models had all the structures and compartments characteristic of an embryo up to day 14, including the placenta, yolk sac, and chorionic sac.

Israeli researchers have developed a synthetic human embryo model using stem cells, bypassing the need for traditional methods. The model exhibits the characteristic structures and compartments found at the developmental stage, allowing for the study of the effects of medicines on real human embryos and potential transplantation. The findings have been published in the journal Nature.

Administration of ranolazine, a drug currently used to treat heart conditions, improves the efficacy of current therapies for melanoma in mouse models of the disease.

Rochester Institute of Technology researchers are improving non-invasive treatment options for degenerative disc disease, an ailment that impacts 3 million adults yearly in the U.S., according to the Mayo Clinic.

The new development has resulted in the first "complete" embryo model for simulating all the important components that form in the early embryo.
