Summary
Single-cell RNA sequencing (scRNA-seq) reveals cellular diversity in pigs, advancing agricultural and biomedical insights. This technology identifies cell types and regulatory networks crucial for reproduction, growth, and immunity.
Area of Science:
- Livestock Science
- Genomics
- Cell Biology
Background:
- Single-cell RNA sequencing (scRNA-seq) is a powerful tool for understanding cellular heterogeneity.
- Pigs are a key species for agricultural and biomedical research, but their cellular complexity requires advanced analytical methods.
- Existing challenges include incomplete genome annotation and technical variability in scRNA-seq.
Purpose of the Study:
- To review the principles and applications of scRNA-seq in porcine biology.
- To highlight how scRNA-seq advances our understanding of pig development, physiology, and disease.
- To discuss future directions for single-cell technologies in livestock science.
Main Methods:
- Profiling transcriptomes at single-cell resolution.
- Generating high-resolution cellular atlases of various porcine tissues (embryos, reproductive organs, immune tissues, muscle, gastrointestinal tract).
- Analyzing cell-type-specific regulatory mechanisms.
Main Results:
- scRNA-seq has significantly improved understanding of porcine developmental processes, physiological regulation, and disease responses.
- Identification of rare cell populations, dynamic cellular states, and lineage trajectories relevant to reproduction, growth, immunity, and metabolism.
- Revealed cell-type-specific regulatory mechanisms linked to reproductive performance, muscle growth, adipogenesis, immune function, and intestinal health.
Conclusions:
- scRNA-seq provides critical insights into porcine biology and production traits.

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.

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
