Abstract Spatial transcriptomics characterizes gene expression profiles while retaining the information of spatial context, providing an unprecedented opportunity to understand cellular systems. One essential tasks in such data analysis is determine spatially variable genes (SVGs), which demonstrate patterns. Existing methods only consider individually and fail model inter-dependence genes. To this end, we present analytic tool STAMarker for robustly determining domain-specific SVGs with saliency maps deep learning. a three-stage ensemble framework consisting graph-attention autoencoders, multilayer perceptron (MLP) classifiers, map computation by backpropagated gradient. We illustrate effectiveness compare it serveral commonly used competing on various transcriptomic generated different platforms. considers all at once more robust when dataset very sparse. could identify characterizing domains enable in-depth region interest tissue section.

Spatially resolved transcriptomic technologies are promising tools to study complex biological processes such as mammalian embryogenesis. However, the imbalance between resolution, gene capture, and field of view current methodologies precludes their systematic application analyze relatively large three-dimensional mid- late-gestation embryos. Here, we combined DNA nanoball (DNB)-patterned arrays in situ RNA capture create spatial enhanced resolution omics-sequencing (Stereo-seq). We applied Stereo-seq generate mouse organogenesis spatiotemporal atlas (MOSTA), which maps with single-cell high sensitivity kinetics directionality transcriptional variation during organogenesis. used this information gain insight into molecular basis cell heterogeneity fate specification developing tissues dorsal midbrain. Our panoramic will facilitate in-depth investigation longstanding questions concerning normal abnormal development.

Tumor evolution is driven by the progressive acquisition of genetic and epigenetic alterations that enable uncontrolled growth expansion to neighboring distal tissues. The study phylogenetic relationships between cancer cells provides key insights into these processes. Here, we introduced an evolving lineage-tracing system with a single-cell RNA-seq readout mouse model Kras;Trp53(KP)-driven lung adenocarcinoma tracked tumor from single-transformed metastatic tumors at unprecedented resolution. We found loss initial, stable alveolar-type2-like state was accompanied transient increase in plasticity. This followed adoption distinct transcriptional programs rapid and, ultimately, clonal sweep subclones capable metastasizing. Finally, develop through stereotypical evolutionary trajectories, perturbing additional suppressors accelerates progression creating novel trajectories.

Human brain development is underpinned by cellular and molecular reconfigurations continuing into the third decade of life. To reveal cell dynamics orchestrating neural maturation, we profiled human prefrontal cortex gene expression chromatin accessibility at single-cell resolution from gestation to adulthood. Integrative analyses define dynamic trajectories each type, revealing major reconfiguration prenatal-to-postnatal transition in all types followed continuous adulthood identifying regulatory networks guiding developmental programs, states, functions. We uncover links between milestones, characterize diverse timing when cells acquire adult-like identify convergence distinct origins. further their regulators implicated neurological disorders. Finally, using this reference, benchmark identities maturation states organoid models. Together, captures landscape cortical development.
