Scientists Create Synthetic Embryos Using Stem Cells, Without Sperm Or Egg: Report

ABP News  

Stem cell research is advancing, and has made it possible to create synthetic embryos without a sperm or an egg. Researchers recently used stem cells to create synthetic embryos, without a sperm or an egg, The Guardian reported. Quoting Żernicka-Goetz, the report said human embryo-like models can be created by the reprogramming of embryonic stem cells. Quoting Robin Lovell-Badge, the head of stem cell biology and developmental genetics at the Francis Crick Institute in London, the report said the idea is that if one really models normal human embryonic development using stem cells, they can gain an "awful" lot of information about how human development begins, and what can go wrong, without having to use early embryos for research.

Lab-grown human ‘embryo’ created without eggs or sperm

The Hindu  

Scientists have developed human embryo-like structures without using sperm, an egg or fertilisation, offering hope for research on miscarriage and birth defects but also raising fresh ethical concerns. But now one group’s research has been published in the peer-reviewed journal Nature, describing how they coaxed human embryonic stem cells to self-organise into a model resembling an early embryo. The researchers …

Synthetic human embryos could allow for research beyond the 14-day limit, but this raises ethical questions

The Hindu  

On June 14, 2023, developmental biologist Magdalena Żernicka-Goetz presented her research on creating human embryos using stem cells at the 2023 annual meeting of the International Society for Stem Cell Research. Beyond the limits Synthetic human embryos — also called embryoid bodies, embryo-like structures or embryo models — mimic the development of “natural human embryos,” those created by fertilization. The …

Human embryo model created from stem cells could help understand why some pregnancies fail

The Hindu  

A model of the human embryo derived from stem cells has been created in the lab, a breakthrough that scientists say could help understand early human development and why and how some pregnancies fail. Derived from pluripotent stem cells, or stem cells able to develop into various different cell types, this embryo model is an organised three-dimensional structure replicating some …

Scientists use stem cells to create models of human embryos and study our earliest days

Associated Press  

Scientists have created embryo models to help study the mysteries of early human development, the medical problems that happen before birth and why many pregnancies fail. “If we can experimentally model this period, then we can finally start asking questions about how human development happens in those very early stages that are normally hidden within the body of the mother,” …

Scientists create mice with cells from 2 males for 1st time

Associated Press  

For the first time, scientists have created baby mice from two males. Still, “It’s a very clever strategy,” said Diana Laird, a stem cell and reproductive expert at the University of California, San Francisco, who was not involved in the research. First, they took skin cells from the tails of male mice and transformed them into “induced pluripotent stem cells,” …

Scientists have created baby mice using cells from two males for the first time. First, they took skin cells from the tails of male mice and transformed them into “induced pluripotent stem cells,” which can develop into many different types of cells or tissues. Laird also said scientists need to be mindful of the mutations and errors that may be …

How scientists grew the world's first 'synthetic' embryo without eggs or sperm

Firstpost  

Researchers from University of Cambridge began their experiment in a lab with three primary embryonic stem cells. Using only a mixture of stem cells taken out from a mouse, scientists from the University of Cambridge were able to create the miracle of life – a synthetic embryo with a beating heart and even a brain. During the first fertilisation in …

In a major medical science breakthrough, scientists have developed the world's first synthetic embryo outside the womb using stem cells cultured in a petri dish. The team tried to emulate what an embryo does and built on two previous advances which include an efficient method for reprogramming stem cells back to a naïve state and using an electronically controlled device …

Our cells are packed with unrealized potential. Basic scientific research into new drugs and treatments often starts with tests in mice, or in the most widely used human cell lines: kidney cells and cervical cancer cells. But testing a potential Alzheimer’s drug on a human brain cell engineered to have signs of Alzheimer’s disease could give a much clearer indication …

Scientists are using human stem cells to create a structure that mimics a pre-embryo and can serve as a research alternative to a real one. “It is extremely difficult to use such human embryos to discover any molecules, genes, principles that might allow us to better understand development and also make biomedical discoveries,” Rivron said. To create the blastoids, Rivron …
