Harmony: fast, sensitive, and accurate integration of single cell data
lock icon

BioTuring

Single-cell RNA-seq datasets in diverse biological and clinical conditions provide great opportunities for the full transcriptional characterization of cell types. However, the integration of these datasets is challeging as they remain biological and techinical differences. **Harmony** is an algorithm allowing fast, sensitive and accurate single-cell data integration.

PopV: the variety of cell-type transfer tools for classify cell-types
lock icon

BioTuring

PopV uses popular vote of a variety of cell-type transfer tools to classify cell-types in a query dataset based on a test dataset. Using this variety of algorithms, they compute the agreement between those algorithms and use this agreement to predict which cell-types have a high likelihood of the same cell-types observed in the reference.

Cell2location: Comprehensive mapping of tissue cell architecture via integrated single cell and spatial transcriptomic
lock icon

BioTuring

Cell2location is a principled Bayesian model that can resolve fine-grained cell types in spatial transcriptomic data and create comprehensive cellular maps of diverse tissues. Cell2location accounts for technical sources of variation and borrows statistical strength across locations, thereby enabling the integration of single cell and spatial transcriptomics with higher sensitivity and resolution than existing tools. This is achieved by estimating which combination of cell types in which cell abundance could have given the mRNA counts in the spatial data, while modelling technical effects (platform/technology effect, contaminating RNA, unexplained variance). This tutorial shows how to use cell2location method for spatially resolving fine-grained cell types by integrating 10X Visium data with scRNA-seq reference of cell types. Cell2location is a principled Bayesian model that estimates which combination of cell types in which cell abundance could have given the mRNA counts in the spatial data, while modelling technical effects (platform/technology effect, contaminating RNA, unexplained variance).

NicheNet: modeling intercellular communication by linking ligands to target genes
lock icon

BioTuring

Computational methods that model how the gene expression of a cell is influenced by interacting cells are lacking. We present NicheNet, a method that predicts ligand–target links between interacting cells by combining their expression data with prior knowledge of signaling and gene regulatory networks. We applied NicheNet to the tumor and immune cell microenvironment data and demonstrated that NicheNet can infer active ligands and their gene regulatory effects on interacting cells.

BayesPrism: Cell type and gene expression deconvolution for bulk RNA-seq data

BioTuring

Reconstructing cell type compositions and their gene expression from bulk RNA sequencing (RNA-seq) datasets is an ongoing challenge in cancer research. BayesPrism (Chu, T., Wang, Z., Pe’er, D. et al., 2022) is a Bayesian method used to predict cellular composition and gene expression in individual cell types from bulk RNA-seq datasets, with scRNA-seq as references. This notebook illustrates an example workflow for bulk RNA-seq deconvolution using BayesPrism. The notebook content is inspired by BayesPrism's vignette and modified to demonstrate how the tool works on BioTuring's platform.
