Single-Cell Sequencing in Precision Medicine

Abstract

The application of next-generation sequencing in cancer genomics allowed for a better understanding of the genetics and pathogenesis of cancer. Single-cell genomics is a relatively new field that has enhanced our current knowledge of the genetic diversity of cells involved in the complex biological systems of cancer. Single-cell genomics is a rapidly developing field, and current technologies can assay a single cell’s gene expression, DNA variation, epigenetic state, and nuclear structure. Statistical and computational methods are central to single-cell genomics and allows for extraction of meaningful information. The translational application of single-cell sequencing in precision cancer therapy has the potential to improve cancer diagnostics, prognostics, targeted therapy, early detection, and noninvasive monitoring. Furthermore, single-cell genomics will transform cancer research as even initial experiments have revolutionized our current understanding of gene regulation and disease.
