A new “embryo-like” model developed in the lab using stem cells has allowed scientists to observe the earliest stages of human development for the first time. Researchers from the University of ...

Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

LONDON, Sept 20 (Reuters) - British scientists have used a genome editing tool known as CRISPR/Cas9 to knock out a gene in embryos just a few days old, testing the technique's ability to decipher key ...

It’s still one of the biggest mysteries in science: How does a human cell — too small to see with the naked eye — divide and reproduce to ultimately become a human body made up of more than 30 ...

A cell aggregation of human pluripotent stem cells and amniotic ectoderm cells generated by the published culture method and mimicking the gastrulation event in human embryos. Gray: nuclei, Cyan: ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

培養条件下でヒト胚の発生の初期段階を最長10～13日間調べた結果を報告する2編の論文が、今週、NatureとNature Cell Biologyに掲載される。ヒト胚が、シャーレで培養された状態であっても自己組織化（細胞分裂と形状再構成が関係する過程）を行い、その際の ...
