Zebrafish neural tissue hosts specialised precursor cells which fuel the ongoing production of neurons into discrete brain regions. To understand how neural maintenance is achieved in this system, we performed a quantitative clonal analysis of the fate of precursor cells. Lineage tracing in growing tissues is complicated by the fact that labelled clones fragment into disconnected clusters, rendering the retrospective analysis of cell fate highly ambiguous. Combining statistical inference with biophysical modelling we reconstructed the clonal origin of labelled cells, revealing that progenitor containing clones persist over the lifetime of the animal. Using stochastic modelling, we unveiled lineage relationships and proliferation kinetics in the adult zebrafish pallium.
