Cell Diversity

4.1K
The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

DNA Microarrays

18.8K
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

RNA-seq03:21

RNA-seq

10.5K
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...

Gene Duplication and Divergence

6.6K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Cell Lines01:16

Cell Lines

8.4K
A cell line is a population of cells grown in vitro that can be subcultured over several generations. Normal cells cease to divide after a certain number of cell divisions, a process known as replicative senescence. This number, called the Hayflick limit, was conceptualized by Leonard Hayflick in 1961 when he observed that fetal cells grown in culture could only divide 40-60 times. This limit is due to the shortening of the telomeres during each round of cell division, preventing cell division...

Area of Science:

  • Genomics
  • Computational Biology
  • Systems Biology

Background:

  • Spatial transcriptomics technologies offer insights into tissue architecture but often lack single-cell resolution.
  • Current methods struggle to resolve continuous gene expression variations within specific cell types across tissue spots.

Purpose of the Study:

  • To develop a novel computational approach, DestVI (Deconvolution of Spatial Transcriptomics profiles using Variational Inference), for high-resolution spatial gene expression analysis.
  • To enable the identification of continuous transcriptome variations within individual cell types in spatial transcriptomics data.

Main Methods:

  • DestVI employs variational inference for deconvolution of spatial transcriptomics profiles.
  • The method was validated using simulations to compare its performance against existing approaches.
  • DestVI was applied to spatial transcriptomics data from infected lymph nodes and a mouse tumor model.

Main Results:

  • DestVI demonstrated superior performance in estimating cell type-specific gene expression within each spatial spot compared to current methods.
  • The application of DestVI revealed high-resolution spatial organization in infected lymph nodes and a mouse tumor.
  • DestVI identified cell-type-specific gene expression changes across different tissue regions and experimental conditions.

Conclusions:

  • DestVI significantly advances the analysis of spatial transcriptomics data by providing accurate, high-resolution cellular and molecular insights.
  • The developed method facilitates a deeper understanding of tissue heterogeneity and cell-type-specific responses in complex biological systems.
  • DestVI is integrated into the open-source scvi-tools package, promoting accessibility and further research in the field.
