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 ...
Scientists in the Brivanlou lab used light-inducible gene expression (yellow circle) and embryo models to demonstrate that, at the start of gastrulation, body-axis formation requires an interplay ...
Pulmonary arterial hypertension (PAH) is a rare condition that's difficult to treat. The hallmarks of the disease—narrowing of the arterioles and capillaries that deliver blood to the lungs—force the ...
Image of mouse embryos at the 2-cell stage visualised by light microscopy. Two blastomeres (cells) can be seen inside the zona pellucida (a “shell-like” protective outer layer) of each embryo. Credit: ...
An international team of scientists has discovered a new cellular mechanism that explains how cells can adapt to pressure changes during tissue growth by packing themselves into a unique shape.
Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...
Magdalena (Magda) Zernicka-Goetz, today a developmental and stem cell biologist at the University of Cambridge and California Institute of Technology, recalled being an artistic child who enjoyed ...
