Single-Cell RNA Sequencing: Technological Progress and Biomedical Application in Cancer Research

Area of Science:

• Genomics
• Molecular Biology
• Biotechnology

Background:

• Single-cell RNA sequencing (scRNA-seq) enables high-resolution genomic analysis of individual cells within a population.
• This technology is crucial for identifying rare cell types associated with cancer, metastasis, and drug resistance.
• scRNA-seq applications extend to understanding cell development and various disease pathologies.

Purpose of the Study:

• To provide a concise overview of current scRNA-seq technology.
• To detail the key technological steps involved in scRNA-seq implementation.
• To highlight existing and potential future applications of scRNA-seq in medicine.

Main Methods:

• Review of current single-cell RNA sequencing (scRNA-seq) methodologies.
• Explanation of the technical workflow for scRNA-seq experiments.
• Analysis of published scRNA-seq data in cancer research.

Main Results:

• scRNA-seq has identified cancer subtypes with poor prognosis and drug resistance (e.g., lung, breast, ovarian, gastric cancers).
• Tumor heterogeneity analysis in lung, breast, and ovarian cancers has been significantly advanced by scRNA-seq.
• The technology reveals genetic variations at the single-cell level, crucial for various biological insights.

Conclusions:

• scRNA-seq is a powerful tool for cancer research, offering insights into tumor heterogeneity and cell dynamics.
• Potential applications include lineage tracing, personalized medicine, disease prediction, and diagnosis.
• This technology facilitates a deeper understanding of biological processes and disease mechanisms at the single-cell level.
