6 core challenges that researchers must consider as the race to create models that are ever closer to real human embryos ...

It's one of life's most defining moments - that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage ...

Scientists have grown a human embryo-like structure in a lab which replicates very early human development - including the production of blood stem cells. The lab-grown embryo model could help ...

The new platform's ethically grounded approach promises to reveal much about how human embryos form during the earliest stages of pregnancy. It's one of life's most defining moments -- that crucial ...

PAX6-dependent epithelial differentiation and developmental trajectories of the ocular surface are elucidated through single-cell RNA sequencing of hiPSC-derived ocular organoids. This study provides ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Researchers have mapped the complex molecular interactions that occur during the earliest stages of human development. New international research shines a light on the role of transcription factors ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

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: ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...
