“…Increasing recognition of these benefits has stimulated efforts to connect discrete and continuum models in a variety of biological contexts [38][39][40][41][42][43][44][45]; see the review by Codling et al [46]. Typically, a lattice-based approach and a mean-field approximation, in which the occupancy of lattice sites is assumed to be independent, are used to derive continuum approximations to discrete models, though corrections to mean-field models have been investigated [47][48][49]. In the context of angiogenesis, Spill et al [50] used a one-dimensional mesoscale lattice-based model to derive macroscopic descriptions of angiogenesis based on the snail-trail approach.…”

“…The short-range interactions experienced by cells often lead to a self-generated spatial structure which can, in turn, have a significant impact on the dynamics of the cell population [14][15][16]. For instance, many cell types are known to form clusters or aggregates as a result of attractive interactions [17,18].…”

“…A slightly higher order scheme is the Kirkwood superposition approximation that retains 〈 s i s j 〉 p ( t ) ( k = 2) but approximates triple correlations ( k = 3) by a function of second-order correlations, is derivable from [22, 22] a constrained maximum-entropy sense of approximation ≈, and has been used in multi-cellular stochastic modeling [23]. Fully dynamic higher order cutoffs to the moment hierarchy for k > 2 include setting higher cumulants to zero [24], dropping higher order terms from the Kramers–Moyal expansion [25] using moment closure functions that would be correct for log-normal rather than Gaussian distributions [26], and ‘equation-free’ moment closure [27] by sparingly invoking fine-scale simulations.…”
