The precursor cells of the spine and ribs are somitic mesoderm cells, which arise from the sides of the embryo's back and form—besides bones—also muscles and parts of the skin. The third group ...

This study shows that glycolysis helps activate key signaling pathways (Wnt, Nodal, and Fgf) that guide cells towards mesoderm and endoderm fates. When glycolysis was blocked, the signals weakened ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state ... they captured an image eight days after culture that included the epiblast, yolk sac, ...
