Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, ...

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as ...

Micropatterned human pluripotent stem cells treated with BMP4 (two-dimensional (2D) gastruloids) are among the most widely used stem cell models for human gastrulation. Due to its simplicity and ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

Stem cell-based embryo models, which recapitulate symmetry breaking, pattern formation and tissue morphogenesis during early development, provide promising experimental tools to study the development ...

Microscopy image of a PGA at day 8 showing the early tissues supporting the embryo, including the amniotic sac and the yolk sac-like structures, surrounded by (extra-embryonic) mesoderm tissue.

New biophysics research adds to our knowledge about the origins of left-right asymmetry in the body. Most animals, including humans, have bilateral symmetry, which means our bodies are pretty ...
