Human embryo models capable of synthesizing their own blood have been developed, in an advance that could lead to new ...

The team used human stem cells to create embryo-like structures dubbed “hematoids” that mirror some features of early human ...

Scientists have created the first detailed day-by-day map of human embryo development using single-cell technology.

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that ...

The team observed the emergence of the three-dimensional hematoids under a microscope in the lab. After just a few days these had self-organised into three germ layers - called the ectoderm, mesoderm, ...

An unexpectedly versatile and regenerative stem cell in early embryos may be key to creating new effective fertility treatments, suggests a new study in mice from the University of Copenhagen. It ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 118, No. 23 (June 8, 2021), pp. 1-10 (10 pages) Markers for the endoderm and mesoderm germ layers are commonly ...

Pluripotent stem cells, created from human skin or mouse ear tissue, are shown here becoming endoderm cells. The endoderm is one of the three primary germ layers that ultimately contribute to the ...

The endoderm, one of the first tissues to form in the mammalian embryo, gives rise to the entire pulmonary system and digestive tract. Despite its importance, it has not been well characterized. In ...
