This research aims to reconstruct cell lineages and their evolutionary relationships from somatic mutations in single-cell transcriptomic data.
Developed Real-Time Course Analysis (RTCA) framework for analyzing single-cell RNA sequencing data.
Conducted simulations to validate the robustness of RTCA against sparse mutation signals and missing data.
Applied RTCA to datasets from healthy human placental samples to reconstruct phylogenetic trees.
RTCA reconstructed bifurcating phylogenetic trees with accuracy, even in sparse data conditions.
Results demonstrated consistency with known placental differentiation pathways, supporting the biological validity of the method.
RTCA provided a more integrated and temporally-informed model of cell trajectories compared to traditional gene expression and pseudotime analyses.
