Unveiling Clonal Cell Fate and Differentiation Dynamics: A Hybrid NeuralODE-Gillespie Approach

ABSTRACT: Recent lineage tracing single-cell techniques (LT-scSeq), e.g., the Lineage And RNA RecoverY (LARRY) barcoding system, have enabled clonally resolved interpretation of differentiation trajectories. However, the heterogeneity of clone-specific kinetics remains understudied, both quantitatively and in terms of interpretability, thus limiting the power of bar-coding systems to unravel how heterogeneous stem cell clones drive overall cell population dynamics. Here, we present CLADES, a NeuralODE-based framework to faithfully estimate clone-specific kinetics of cell states from newly generated and publicly available human cord blood LARRY LT-scSeq data. By incorporating a stochastic simulation algorithm (SSA) and differential expression gene (DEGs) analysis, CLADES yields cell division dynamics across differentiation timecourses and fate bias predictions for the early progenitor cells. Moreover, clone-level quantitative behaviours can be grouped into characteristic types by pooling individual clones into meta-clones. By benchmarking with CoSpar, we found that CLADES improves fate bias prediction accuracy at the meta-clone level. In conclusion, we report a broadly applicable approach to robustly quantify differentiation kinetics using meta-clones while providing valuable insights into the fate bias of cellular populations for any organ system maintained by a pool of heterogeneous stem and progenitor cells.

Cell of origin epigenetic priming determines susceptibility to Tet2 mutation

Project description:Hematopoietic stem cell (HSC) mutations can result in clonal hematopoiesis (CH) with heterogeneous clinical outcomes. Here, we investigated how the cell state preceding Tet2 mutation impacts the pre-malignant phenotype. Using an inducible system for clonal analysis of myeloid progenitors, we found that the epigenetic features of clones at similar differentiation status were highly heterogeneous and functionally responded differently to Tet2 mutation. Cell differentiation stage also influenced Tet2 mutation response indicating that the cell of origin's epigenome modulates clone-specific behaviors in CH. Molecular features associated with higher risk outcomes include Sox4 that sensitized cells to Tet2 inactivation, inducing dedifferentiation, altered metabolism and increasing the in vivo clonal output of mutant cells, as confirmed in primary GMP and HSC models. Our findings validate the hypothesis that epigenetic features can predispose specific clones for dominance, explaining why identical genetic mutations can result in different phenotypes.

Identification of GP33-specific CD8 T cell clones responding to chronic infection with LCMV-Clone13

Project description:T cells specific for a certain antigen are a heterogeneous population characterized by cells expressing different T Cell Receptors (TCRs). As the TCR determines the avidity of a T cell clone for its cognate antigen, this feature has also a significant impact on the fate of such clone during antigenic challenge. In the context of chronic viral infection, T cells specific for the chronic virus differentiate into exhausted cells with limited functionality. We find that, in the process of exhaustion following infection with LCMV-Clone13, certain clones of CD8 T cells specific for the LCMV immunodominant epitope GP33 are enriched compared to others.

Single-cell derived clones from human adipose stem cells present different immunomodulatory properties.

Project description:Human adipose mesenchymal stem cells are a heterogeneous population, where cell cultures derived from single cell-expanded clones present varying degrees of differential plasticity. This work focuses on the immunomodulatory/anti-inflammatory properties of these cells. To this end, 5 single cell clones were isolated (1.X and 3.X) from 2 volunteers. Regarding the expression level of the lineage-characteristic surface antigens, clones 1.10 and 1.22 expressed the lowest amounts, while clones 3.10 and 3.5 expressed more CD105 than the rest and clone 1.7 expressed higher amounts of CD73 and CD44. Regarding cytokine secretion, all clones were capable of spontaneously releasing high levels of IL-6 and low to moderate levels of IL-8. Furthermore, clone 3.X produced the highest amounts of pro-inflammatory cytokines such as IL-1β, while clones 1.10 and 1.22 highly expressed IL-4 and IL-5. These differences can be explained in part by the distinct DNA promoter methylation profile exhibited by the clones. The results of this work indicates that this stem cell population is heterogeneous in its secretion profile, and that isolation, characterization and selection of the appropriate cell clone is a more exact method for the possible treatment of different patients or pathologies.

Somatic epimutations enable native single-cell clonal tracking on hematopoietic cell state landscapes across the murine and human lifespan

Project description:Current approaches to track stem cell clones through differentiation require genetic engineering or rely on sparse somatic DNA variants. Here, we show that targeted single-cell measurements of DNA methylation at single-CpG resolution deliver joint information about cellular differentiation state and clonal identities. We develop EPI-clone, a method for transgene-free lineage tracing based on microfluidic, targeted single-cell DNA methylation analysis. Applied to mouse and human hematopoiesis, we captured hundreds of clonal differentiation trajectories across tens of individuals and almost 400,000 single-cells. Using ground-truth genetic barcodes, we demonstrate that EPI-clone accurately identifies clonal lineages throughout hematopoietic differentiation while at the same time providing cell state resolution similar to transcriptomic data. Applied to unperturbed hematopoiesis in murine ageing, we demonstrate that myeloid bias and low output of old HSCs are restricted to a small number of expanded developmental clones, while many functionally young-like clones persist in old age. In human ageing, we demonstrate that clones carrying CHIP mutations are part of a spectrum of age-related expansions of low-output clones. EPI-clone is compatible with the multiplexed readout of surface protein, somatic variants and RNA from the same single cell. Taken together, EPI-clone enables accurate and transgene-free single-cell lineage tracing on hematopoietic cell state landscapes at scale.
