arXiv:2605.18587v2 Announce Type: replace-cross Abstract: Single-cell trajectory inference from destructive time-course snapshots is fundamentally ill-posed: neither cross-time cell correspondences nor continuous trajectories are observed, so the snapshot distributions alone do not uniquely determine the underlying dynamics. Existing optimal transport and flow-based methods typically couple cells by Euclidean proximity at observed clock times, which can misalign trajectories when development is asynchronous and cells sampled at the same experimental time occupy different latent pseudotime stag
The continuous advancements in AI and computational biology are pushing the boundaries of single-cell analysis, identifying key challenges like trajectory inference.
Improved single-cell trajectory inference provides a more accurate understanding of biological processes, essential for drug discovery, disease mechanisms, and synthetic biology applications.
New methods like PACE address fundamental limitations in current single-cell analysis by accounting for asynchronous development, leading to more robust and accurate biological insights.
