Abstract
Lineage-tracing methods have enabled characterization of clonal dynamics in complex populations, but generally lack the ability to integrate genomic, epigenomic and transcriptomic measurements with live-cell manipulation of specific clones of interest. We developed a functionalized lineage-tracing system, ClonMapper, which integrates DNA barcoding with single-cell RNA sequencing and clonal isolation to comprehensively characterize thousands of clones within heterogeneous populations. Using ClonMapper, we identified subpopulations of a chronic lymphocytic leukemia cell line with distinct clonal compositions, transcriptional signatures and chemotherapy survivorship trajectories; patterns that were also observed in primary human chronic lymphocytic leukemia. The ability to retrieve specific clones before, during and after treatment enabled direct measurements of clonal diversification and durable subpopulation transcriptional signatures. ClonMapper is a powerful multifunctional approach to dissect the complex clonal dynamics of tumor progression and therapeutic response.

Previously published whole-exome sequencing data for fludarabine and ibrutinib-treated patients were from dbGaP with accession numbers phs000922.v1.p1 and phs001431.v1.p, respectively. Previously published scRNA-seq data for ibrutinib-treated patients are available from dbGaP with accession number phs2335.v1. All other data supporting the findings of this study are available from the corresponding authors on reasonable request. Source data are provided with this paper.

The single-cell RNA data were processed using Cell Ranger v.3.1 (https://www.10xgenomics.com/) and analyzed with the Python package scanpy v.1.4.5 (https://scanpy.readthedocs.io/en/stable/). Barcode sequence processing was conducted using our cashier algorithm (v.0.1) (https://github.com/brocklab/cashier). Code for modeling growth dynamics is also available on GitHub (https://github.com/kej1993johnson/Lineage_transitions). Any additional code is available from the corresponding authors upon request.
