《自然》本周发表的一项研究Human blastoids model blastocyst development and implantation建立了一个模型，可以用来研究人类胚胎植入子宫的过程。人胚状体（blastoid）是模拟早期人类胚胎的结构，在研究中能准确复现人类胚胎早期发育的关键阶段，包括黏附在体外子宫细胞 ...

Rapid population growth and infertility are two significant global issues that concern women's health. These issues are greatly influenced by the events of preimplantation embryonic development and ...

The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, researchers argue that bovine embryos might well be a better model for early human ...

The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, Ludwig-Maximilians-Universitaet (LMU) in Munich researchers argue that bovine embryos might ...

The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

Osaka, Japan - The early development of embryos is not well understood. One necessary stage is the formation of the blastocyst, a collection of cells present by about 4 days after fertilization of the ...

Innovative research, presented today at the ESHRE 40 th Annual Meeting in Amsterdam, has introduced a novel 3D imaging model designed to identify features of blastocysts – the early stage of ...

The embryos of many species can stop developing when starved of nutrients, only to restart the process once these are restored – and scientists may have figured out how they do it. In the early stages ...

The embryo on the left is unedited, whereas the right has been edited to prevent it producing the OCT4 protein. The unedited embryo forms a stable structure called a 'blastocyst' but the edited embryo ...

Researchers have very limited opportunities to study the earliest stages of human development, but a groundbreaking discovery led by a team in Australia will now provide them with a valuable new model ...
