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 ...

Scientists at the Leibniz Institute on Aging—Fritz Lipmann Institute (FLI) in Jena have discovered a previously unknown function of immune cells in the bone marrow. Embryonic macrophages—specialized ...

The musculoskeletal system provides structural support, enabling movement such as walking and lifting, protecting internal organs, maintaining posture, generating heat through muscle activity, and ...

Embryonic morphogenesis encompasses the coordinated processes by which a fertilised egg acquires form and function through spatial and temporal regulation of cell behaviour. Key mechanisms include ...

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the University of Basel have now discovered that these skeletal cells do not just ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...
