I'm reading an article where they claim that transcriptional bursting could play a role in cell-to-cell variability.
Cell-to-cell variability plays a critical role in cellular responses and decision-making in a population, and transcriptional bursting has been broadly studied by experimental and theoretical approaches as the potential source of cell-to-cell variability.
I was looking for a definition of Cell-to-cell variability and I found only the one of Single-cell variability
In cell biology, single-cell variability occurs when individual cells in an otherwise similar population differ in shape, size, position in the cell cycle, or molecular-level characteristics. Such differences can be detected using modern single-cell analysis techniques. Investigation of variability within a population of cells contributes to the understanding of developmental and pathological processes.
