ETS-Embryo Medium supports the development of artificial embryo structures, known as ETS-embryos, when trophoblast stem cells and embryonic stem cells are co-cultured.
A 2017 landmark study of trophoblast and embryonic stem cells (ESCs) has produced a breakthrough for stem cell research. Prof Magdalena Zernicka-Goetz and her colleagues at Cambridge University found that simply growing these two cells together leads to the development of "artificial embryo" structures termed ETS-embryos (Embryonic Trophoblast Stem embryos). These ETS-embryos strongly resemble mouse embryos in the days immediately following their implantation into the womb. Key to this success was development of “ETS-Embryo Medium” to culture the two stem cell types.
The efficiency of the process is remarkable. Just under 20% of the clusters of cells identified in co-cultures of trophoblast and embryonic stem cells were ETS-embryos. This efficiency offers the prospect of new applications, beyond the scope of embryo research. ETS-embryos are set to transform stem cell science. Potential applications include improving the efficiency of generation of transgenic animals for research and novel ways to make tissues and organs for stem cell research.
