Single-Cell Epigenomics is a field of study that focuses on understanding the epigenetic modifications in individual cells. Epigenetics refers to changes in gene expression that do not involve alterations to the underlying DNA sequence. By examining these modifications at the single-cell level, researchers can gain insights into how different cells within the same organism can have distinct functions and behaviors. This approach allows scientists to explore cellular diversity, track developmental processes, and investigate disease mechanisms. Techniques used in Single-Cell Epigenomics include single-cell RNA sequencing and ATAC-seq, which help identify regulatory elements and gene activity in individual cells, providing a more detailed picture of cellular function.
