2023年9月6日 · 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,...

2024年9月11日 · Dozens of labs around the world are striving to grow models of human embryos to study development, fertility and therapies. They are entering uncharted ethical territory. Models of human embryos at...

2023年9月6日 · Created without egg, sperm, or womb, the synthetic embryo models may open new avenues of research into infertility, drug testing, and growth of tissues for transplant – as well as help scientists peer into the dramatic first weeks of embryonic development.

2023年9月6日 · Embryo-like models with spatially organized morphogenesis and structure of all defining embryonic and extra-embryonic tissues of the post-implantation human conceptus (that is, the embryonic...

2024年10月3日 · We present the stem cell types and stem cell-based embryo models, their advantages and limitations, and highlight efforts to overcome bottlenecks. Human embryonic development starts with the formation of the zygote, which undergoes cleavage divisions to form the embryo and extra-embryonic tissues.

2023年10月26日 · Recent breakthroughs in making stem-cell based human embryo models are raising urgent questions about to what extent they should be treated like natural embryos and whether they are open to...

2023年6月27日 · Cambridge scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why and how pregnancies fail.

2023年9月7日 · These lab-made embryo models open a window into the earliest stages of human development, when a fertilized egg first starts dividing and implants in the wall of the uterus.

Embryo-like models with spatially organized morphogenesis and structure of all defining embryonic and extra-embryonic tissues of the post-implantation human conceptus (that is, the embryonic disc, the bilaminar disc, the yolk sac, the chorionic sac and the surrounding trophoblast layer) remain lacking 1,2.

2023年12月6日 · The human embryo develops into a disc-like structure, unlike the cup-like organization of the mouse embryo; pluripotent cells of the human embryo split into two unique groups, unlike the...
