The heterogeneity in a cell population
WebMay 14, 2010 · Heterogeneity is essentially a statistical property of cellular populations. A distribution of cellular behaviors can be estimated from observations of a small number of cells over a long time, or a large number of cells at a single time point. Webtion of such population systems with heterogeneity among its individuals [16], [17]. In cell populations, this heterogeneity, the particle state, may be e.g. cell mass or size, cell age or enzyme content [18], [19]. In this work, the cell mass is considered as single state x, that is expected to evolve over time described by ˙x = m(x)x.

WebNov 8, 2024 · There are two limiting types of heterogeneity in a cell population: cellular heterogeneity and temporal heterogeneity. Cellular heterogeneity accounts for the cell-to-cell variation in migration capacity, while temporal heterogeneity arises from the temporal noise in the migration capacity of single cells.
