“…Although several attempts can infer the cell-type proportions from traditional RNA-seq data, understanding bulk tissue at single-cell spatial resolution remains a pressing need in the field. Cell identity can be characterized by the clustering space of single-cell gene expression profiles 59 , and expression features can be stably retained across different conditions, technologies, and species 29 . Based on this, we used a deep learning model, termed β-VAE, to generate single-cell profiles with biological significance within the clustering space of each cell type and map them accurately to tissue coordinates, thus deconvolving the bulk transcriptomics into spatially resolved single-cell transcriptomics data.…”

“…However, there is no clear clinical meaning for pseudocells, so it is not reliable to explain underlying biological processes based upon WGCNA module analysis. Particularly, it is important to identify genes associated with dynamic changes during disease development or embryogenesis [49] , which is a difficult task for these methods. To address these challenges, we proposed scDisProcema, which, on the one hand, utilized the information obtained from upstream analysis of single-cell data.…”

“…Therefore, accurately characterizing the temporal dynamics of gene expression over time points is crucial for developmental biology [10,11], tumor biology [12][13][14], and biogerontology [15][16][17], which allows us to decipher the dynamic cellular heterogeneity during cell differentiation [18]; identifying cancer driver genes during the status transformation [14]; and investigating the mechanisms of cell senescence during aging [15]. Although the time-resolved and time-course scRNA-seq studies are initially designed for different purposes, they both require the same data analysis tools for detecting the temporal dynamics of gene expression [19]. As we know, the statistical modeling for both types of scRNA-seq data to identify temporal gene expression patterns meets significant challenges, i.e., modeling unwanted variables, accounting for temporal dependencies, and even characterizing nonstationary cell populations of scRNA-seq data.…”
