Cover Story: We propose single-cell topological simplicial analysis (scTSA), a topological data analysis framework to analyze high-throughput time series data. Applying this approach to single-cell gene expression profiles from local networks of cells in different developmental stages reveals a previously unseen topology of cellular ecology. These networks contain an abundance of cliques of single-cell profiles bound into cavities that guide the emergence of more complicated habitation forms. We visualize these ecological patterns with their topological simplicial architectures and highlight critical developmental stages. As a nonlinear, model-independent, and unsupervised framework, scTSA can be applied to tracing multi-scale cell lineage, identifying critical stages, or creating pseudo-time series. View this paper
