Story summary
- U.S. researchers led by scientist Stan Kerstjens in Professor Anthony Zador’s lab reported that brain cells stay near their ancestral cells, forming a lineage-based positional system alongside chemical signals.
- They built a scalable lineage-based model, first testing it with theoretical calculations and then with mouse brain gene-expression data.
- Similar lineage patterns appeared in zebrafish, suggesting the mechanism works across species and could apply to other tissues, tumors, and AI systems.
