How to build a mouse: embryo development captured in stunning detail
Scientists have created the largest mammal cell family tree to date by tracing 1.3 million embryonic cells back to a single origin. Using a redesigned DNA Typewriter and gene-editing technology, researchers recorded the lineage of a mouse embryo from its first two cells through 13.5 days of development. This process captured the precise timing of when cells commit to specific fates and form organs. Two independent teams published these findings on 8 October in the journals Science and Cell.

Researchers Map Mouse Embryo Development Using DNA Typewriter
Scientists have created the largest mammal cell family tree to date by tracing 1.3 million embryonic cells back to a single origin. Using a redesigned DNA Typewriter and gene-editing technology, researchers recorded the lineage of a mouse embryo from its first two cells through 13.5 days of development. This process captured the precise timing of when cells commit to specific fates and form organs. Two independent teams published these findings on 8 October in the journals Science and Cell.
Why it matters
Previous embryonic research relied on snapshots of specific organs or moments in time. This continuous recording provides a framework to study how cell types emerge on individual schedules. The data may help explain the origins of cancer, genetic disorders, and birth defects.
What is confirmed
- Two independent research teams published their findings in Science and Cell on 8 October.
- Researchers used a DNA Typewriter to trace the lineage of 1.3 million cells in a mouse embryo.
- The recording tracked development from the first two cells for 13.5 days.
- Full gestation for mice typically lasts 19 to 21 days.
- The study used gene-editing technologies to trace development from a single fertilized egg to a late-stage embryo.
What to watch next
- Application of DNA recording systems to human embryonic development
