  1. ...stripes and vertical stripes, or spatial clustering domains. Polyomino first maps cells to bins. In this process, the different regionalization layers are used to jointly constrain the spatial localization of single cells, and each cell is assigned to the bins with the highest mapping probability. Given...
  2. ...resolution.To address these issues, we propose a model-based deep hyperbolic manifold learning approach: single-cell deep hierarchical map (scDHMap) (Fig. 1). To characterize the overdispersed and zero-inflated count matrix of the scRNA-seq data, we apply a zero-inflated negative binomial (ZINB) model-based...

  4. ...that are further compounded by the higher cost of spatial data compared to traditional single-cell data. To overcome this challenge, we introduce spRefine, a deep learning framework that leverages genomic language models to jointly denoise and impute spatial transcriptomic data. Our results demonstrate that sp...
  5. ...). In addition, CytoSignal (Liu et al. 2024) and DeepTalk (Yang et al. 2024) decipher spatial CCC at single-cell resolution. Although these methods provide promising advancement in CCC inference, the elaborate mechanisms underlying CCC have not been fully exploited. In fact, the signaling mechanisms within CCC...

(2) Microenvironmental deconstruction: trains a cell-to-spot mapping matrix M using spatial transcriptomic (ST) gene expression data (Xst) and single-cell data (Xsc) via a spatially informed contrastive learning model. In this model...

Various platforms such as Pacific Biosciences (PacBio) (Eid et al. 2009; Koren et al. 2012; Au et al. 2013; Sharon et al. 2013; Tilgner et al. 2014; Weirather et al. 2015), Oxford Nanopore...
