'It’s beautiful and created entirely from embryonic stem cells.'
But it hasn't been published just yet, meaning that many experts are waiting before they comment.
The cells were grown from human embryonic stem cells and were manipulated to develop cells that typically lead to the formation of a yolk sac, placenta, and the embryo itself. "Our human model is the first three-lineage human embryo model that specifies amnion and germ cells, precursor cells of egg and sperm," Zernicka-Goetz toldGiven the extremely sensitive nature of the research, Zernicka-Goetz was measured in her statements to the media, but still stressed the importance of her work..
And her team's latest efforts are only the beginning of translating this concept into human models. Many challenges remain and even in the case of mice, these synthetic embryos have yet to be successfully grown into live animals inside the womb.didn't make it past a couple of daysAnd then there's the question of regulating human-embryo research.
"These findings suggest that we would soon develop the technology to grow these cells beyond the 14-day limit, with potentially more insights to gain into human development," Ildem Akerman, a gene regulation researcher from the University of Birmingham,
