Using a new fluorescent mouse model with advanced imaging techniques, researchers have successfully visualized how musculoskeletal components are integrated into the functional locomotor system during ...

Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize ...

Sox9, a master regulator of cartilage formation, switches its target genes dynamically during embryonic limb development instead of following a fixed program, as reported by researchers from Science ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

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 ...

Scientists' discovery of a molecular "switch" that activates an energy-burning pathway in mice has the potential to lead to new treatments for bone disease. The study, published in Nature, sheds new ...
