“…Once the colony reaches a critical size it reorganizes itself into a slug, whose movement (and the following stages of fruiting body and spore formation) are all controlled by pulsing spiral waves of cAMP spreading from the front to the back end of the colony. Mathematical models based on reactiondiffusion-type processes, incorporating only cAMP production and transport, perfectly explain the overall behaviour (Cohen and Robertson, 1971;Martiel and Goldbeter, 1987;Tyson et al, 1989).…”

“…Unfortunately, when he tried to publish his findings (see Belousov, 1951), the referees rejected his manuscript, because they claimed his ‘supposed discovery’ was quite impossible (they did not seem to have been aware of the findings of either Lotka or Bray). Belousov tried again to publish his findings 6 years later, but once more without success (Winfree, 1984; Zhabotinsky, 1985; Tyson and Kagen, 1988; Coveney and Highfield, 1990). Like Lotka before him, Belousov took this refusal very much to heart and retired from academic research.…”

“…Researchers successfully described the striped patterns of seashells (Meinhardt and Klingler, 1987) and the coats of various mammals, such as leopards (Murray, 1988). From the early 1970s, this approach was used to successfully describe the various patterns that develop during the early stages of embryogenesis (Meinhardt, 1982;Tyson et al, 1989;Harrison, 1993). Although, much of this modelling was successful, it suffered from the limitation that the molecular species hypothesized as being involved were at the time unidentified.…”

Historical and conceptual background of self‐organization by reactive processes

Order, form, pattern and organization are properties central to much living matter. The physicochemical processes by which an initially homogeneous solution of reacting chemicals or biochemicals might self-organize is hence a question of fundamental biological importance. In most cases, solutions of reacting chemicals in a test-tube do not self-organize. Because of this, for many years, it was not thought possible that reactive processes could result in self-organization. However, progressively over the last hundred years, it has been shown that this is not always the case, and under certain conditions, the combination of reaction with molecular diffusion can lead to macroscopic self-organization. In 'complex' systems comprised of populations of strongly coupled elements, new 'emergent' properties, such as self-organization, arise by way of the dynamics of the system. Self-organizing reaction-diffusion systems form a specific type of complex system. Here, I will give a personal overview of the conceptual and historical background to this approach with an emphasis on biological self-organization.

“…Nevertheless, it has been established, both theoretically [15,16] and experimentally [17][18][19], that this is not always the case and that some reactive systems can self-organise by behaving as a complex system in which molecular species are coupled together in a non-linear manner by a combination of reaction and diffusion [20] . In addition, it has been predicted theoretically that in some cases the presence at a critical moment early in the process of a weak external factor, such as gravity or a magnetic field, which breaks the symmetry of the process can determine the selforganised morphology that subsequently develops [21] .…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT ABSTRACTWeightlessness is known to effect cellular functions by as yet undetermined processes.Many experiments indicate a role of the cytoskeleton and microtubules. Under appropriate conditions in vitro microtubule preparations behave as a complex system that self-organises by a combination of reaction and diffusion. This process also results in the collective transport and organisation of any colloidal particles present. In large centimetre-sized samples, selforganisation does not occur when samples are exposed to a brief early period of weightlessness. Here, we report both space-flight and ground-based (clinorotation) experiments on the effect of w eightlessness on the transport and segregation of colloidal particles and chromosomes. In centimetre-sized containers, both methods show that a brief initial period of weightlessness strongly inhibits particle transport. In miniature cell-sized containers under normal gravity conditions, the particle transport that self-organisation causes results in their accumulation into segregated regions of high and low particle density. The gravity dependence of this behaviour is strongly shape dependent. In square wells, neither self-organisation nor particle transport and segregation occur under conditions of weightlessness. On the contrary, in rectangular canals, both phenomena are largely unaffected by weightlessness. These observations suggest, depending on factors such as cell and embryo shape, that major biological functions associated with microtubule driven particle transport and organisation might be strongly perturbed by weightlessness.
