Web30 mrt. 2024 · Delineating quiescence and dormancy. Quiescence (noun) is a labile state of a cell, embryonic or meristematic structure, where division of the cell or cell population is repressed by non-cell-autonomous processes. Cell division may not have ceased or stalled, and evidence suggests that mitosis continues even in stem cell populations.
