Single-Cell DNA Methylation Profiling

What is single-cell DNA methylation?

Single-cell DNA methylation profiling provides a high-resolution view of how epigenetic regulation defines cell identity, lineage, and function. Unlike bulk methylation assays that average signals across many cells, single-cell approaches uncover cellular heterogeneity, revealing rare subpopulations and dynamic regulatory states that drive development, disease progression, and therapeutic response.

At the single-cell level, DNA methylation analysis allows scientists to map cell fate decisions, lineage trajectories, and epigenetic variability across tissues or within tumors. These insights are transforming developmental biology, oncology, and neurobiology, linking cell-specific methylation landscapes to functional phenotypes and gene regulation networks.

Applications if single-cell epigenetic research

Single-cell DNA methylation technologies are revolutionizing how researchers study gene regulation and cellular diversity. They are used to:

Dissect cell populations and identity by defining methylation-based cell-type–specific signatures.
Reconstruct lineage trajectories and differentiation pathways during embryogenesis, tissue regeneration, or organoid development.
Investigate tumor heterogeneity and drug resistance through cell-level methylation profiling of cancer subclones and minimal residual disease.
Explore aging and environmental effects on individual cells’ epigenetic states and transcriptional potential.
Integrate multi-omic data, combining single-cell methylation with RNA-seq or ATAC-seq to link regulatory mechanisms to gene expression and chromatin accessibility.

By enabling quantitative, cell-by-cell resolution, single-cell methylation profiling provides the foundation for a new generation of precision epigenetics, offering insights into the molecular basis of health, disease, and development.
