  • More specifically, the lineage-tracing experiments showed that FOXC2-producing uSPGs could produce paired uSPGs that would then either divide to form two single uSPGs (including some that retained Foxc2 expression), or form chains of aligned uSPGs containing at most one FOXC2-producing cell ( Figure 1A ). (elifesciences.org)
