- Clusters of mouse embryonic stem cells called embryoid bodies more closely approximate true embryos in organization and structure than previously thought, according to researchers at the Stanford University School of Medicine. Harnessing the signals that influence the cells' fate may help researchers more accurately direct the differentiation of embryonic stem cells for use in therapy.
The researchers found
that embryoid bodies have hallmarks of gastrulation -- a remarkable developmental step that launches a hollow ball of cells toward becoming an organism with three distinct types of precursor cells. The scientists showed that this process is initiated by a single signaling pathway in embryoid bodies and in real embryos. Enhancing or blocking this signal affects what the cells become, the scientists found.
