Sharing a new data visualization from our ongoing work on clonal dynamics in therapy-resistant malignancies. Figure title: "Subclonal expansion and cancer stem cell enrichment across therapy phases" Subtitle: "Simulated clonal trajectories: therapy-resistant subclones expand as CSC fraction rises through relapse" The visualization employs a clonal fan slopegraph, in which branching subclone trajectories are tracked across four discrete treatment phases (diagnosis, induction response, minimal residual disease, and relapse). Each terminal branch corresponds to a genetically distinct subclone, with vertical position encoding its relative population frequency and branch width scaled to absolute clone size. Superimposed CSC-fraction ribbons quantify the proportion of cells within each subclone bearing a cancer stem cell (CSC) phenotype, operationally defined here by a composite stemness signature. I want to emphasize that the underlying data are simulated. The trajectories are generated from a stochastic branching model parameterized to reproduce a well-documented, literature-grounded trend rather than to represent a specific empirical cohort. The intent is illustrative and hypothesis-clarifying. The central pattern is instructive. Under cytotoxic pressure, dominant treatment-sensitive subclones contract sharply during induction, producing an apparent response, while minor subclones harboring resistance-conferring lesions persist through the MRD bottleneck. Critically, these persistent subclones exhibit disproportionately elevated CSC fractions, consistent with the notion that quiescent, stemness-associated states underwrite drug tolerance and subsequent regrowth. During relapse, the resistant subclones undergo expansion, and the population-level CSC fraction rises accordingly, reflecting both selection and plasticity-driven state transitions.

Sharing a visualization from ongoing work on cancer stem cell (CSC) clonal dynamics under therapeutic pressure. Figure: "Therapy reshapes clonal hierarchy via stem-like subclone selection" Subtitle: "Ranked clonal fraction of tumor subclones across treatment phases; stem-marked clones rise under selective pressure" The chart is a phylogenetic bump plot (Muller-style ranked clonal flow) tracking the relative clonal fraction of individual subclones across sequential treatment phases: baseline, on-treatment, minimal residual disease (MRD), and relapse. Each ribbon corresponds to a distinct subclone, with vertical band thickness encoding clonal fraction and vertical ordering encoding rank. Subclones carrying stem-associated marker states (e.g., high ALDH activity, CD133/CD44 enrichment, quiescence-linked transcriptional programs) are highlighted to distinguish them from bulk proliferative lineages. The illustrated trajectory recapitulates a well-documented pattern: cytotoxic selection preferentially depletes proliferative, differentiation-committed subclones while sparing slow-cycling, stem-marked populations. During the MRD window, stem-like ribbons ascend in rank despite overall tumor contraction, consistent with therapy-tolerant persister states buffered by quiescence, enhanced drug efflux, and reinforced self-renewal signaling (WNT, NOTCH, Hedgehog). At relapse, these ascended subclones seed the reconstituted hierarchy, producing a repopulated tumor with an altered clonal architecture rather than a faithful reconstruction of the baseline composition. I want to emphasize that the underlying data here are simulated. The intent is to render a literature-grounded trend in an interpretable topological format, not to present empirical measurements. The parameterization draws on reported CSC plasticity and selection dynamics, but ribbon values are synthetic.

We believe human #epithelioids could serve as a new experimental #platform to study epithelial #biology, #clonalevolution, #cellcompetition, tissue responses to #clinical #therapies, and molecular #cancerprevention.

Using this approach, we followed human #epithelioids for 8 months in continuous culture. #Mutationburden, #mutationalsignatures and #clonalcomposition remained remarkably stable over time, opening the door to #longitudinal studies of #clonalevolution in human tissues in vitro.
