Lineage tracing reveals how cells help the salamanders regrow chopped-off limbs.

The tools researchers used to study how this amphipod’s limbs develop could help inform our understanding of cell lineages and fates.

The biologist earned a Nobel Prize in 2002 for his work on C. elegans.

Researchers continue to identify new T-cell subtypes—and devise ways to use them to fight cancer. The Scientist attempts to catalog them all.

Advice on how to deploy the latest techniques in your own lab

Scientists create a CRISPR-based, self-editing cellular–barcoding system for extensive molecular recording.

Sequencing and gene-editing advances make tracing a cell’s journey throughout development easier than ever.
