Relative decrease in number of earthquakes or energy in any area of a seismic active region within a certain time interval in comparison with long-term observations in the same region. The quiescence and potency of hematopoietic stem cells (HSCs) are thought to be maintained by glycolysis. Quiescent cells are often identified by low RNA content, lack of cell proliferation markers, and increased label retention indicating low cell turnover.
