DNA Typewriter Records Cell History in Developing Mouse Embryo
Scientists have successfully reconstructed the complete family tree of cells in a developing mouse embryo using an innovative technique known as the 'DNA typewriter.' This method recorded the lineage relationships of cells over a critical 13.5-day period. The tracking began from the moment the fertilized egg first split in two and continued until the body and its major organs fully took shape. This breakthrough provides unprecedented detail into embryonic development.
