Progenitor cells that will contribute to formation of specific heart tissues are derived from distinct regions of the primitive streak in the developing mouse embryo. This study utilizes light-sheet ...

Here we determine the embryonic origin of scales and fin rays of medaka (teleost trunk exoskeletons) by applying long-term cell labelling methods, and demonstrate that both tissues are mesodermal ...

The second wave directs glucose through glycolysis, providing energy and metabolites necessary for mesodermal cell migration and lateral expansion. The team mapped the spatial and temporal ...
