1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Time-series spatial transcriptomics with single-cell resolution provides an opportunity to study cell differentiation, proliferation and migration in physical space over time. However, because sequencing is destructive, reconstructing spatiotemporal dynamics from snapshots remains challenging. In particular, inferring migration is difficult because samples collected at different time points often lie in different coordinate systems across biological replicates. Here we show that spatiotemporal video cassette recorder (stVCR), a generative deep-learning framework, can reconstruct continuous cell differentiation, proliferation, physical-space migration and spatial alignment in an end-to-end manner. The model integrates dynamical optimal transport in an unbalanced setting, density matching that is invariant to rigid transformations, and biologically informed priors to preserve spatial structure. stVCR also enables interpretable analysis of how phenotype transitions interact with spatial migration and proliferation. Using both simulated and real datasets, we demonstrate that stVCR is effective and robust, and we apply it to uncover spatiotemporal dynamics in axolotl brain regeneration and 3D Drosophila embryo development.
