RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Overview Of Cell Separation And Isolation

Overview Of Cell Separation And Isolation

Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.

Area of Science:

Spatial transcriptomics
Computational biology
Genomics

Background:

Spatial transcriptomic techniques offer cellular resolution insights but face challenges with large datasets.
Current cell-type deconvolution methods struggle with the unique characteristics of spatial transcriptomic data.

Purpose of the Study:

To introduce stVAE, a variational autoencoder-based method for cell-type deconvolution in cellular resolution spatial transcriptomic datasets.
To evaluate stVAE's performance on diverse biological tissues and datasets.

Main Methods:

Developed stVAE using a variational autoencoder framework.
Applied stVAE to five spatial transcriptomic datasets from mouse brain, embryo, and olfactory bulb.
Validated results using known tissue structures and marker genes.

Main Results:

stVAE accurately reconstructed the laminar structure of mouse cortex pyramidal cell layers.
Identified spatial patterns of osteoblast subtypes in the developing mouse embryo.
Delineated cell-type distributions in the mouse olfactory bulb.
Demonstrated stVAE's capability to identify cell types and their proportions in spatial transcriptomic data.

Conclusions:

stVAE effectively deconvolves cell-type composition from cellular resolution spatial transcriptomic data.
The method accurately identifies spatial patterns and proportions of cell types.
stVAE is valuable for studying cellular heterogeneity and tissue interactions.
