From transient compartmentalization to cell population dynamics
In the fifties, Oparin imagined liquidlike compartments called
coacervates, which could have played a central role in the origin of life .
Although the experimental verification of this idea remained scarce for many
years, the idea resurfaced recently in various systems of biological interest
in which liquid non-membrane compartments were found. An important aspect
not tested in the Oparin scenario is the role of the transient nature of
compartmentalization. Here, we discuss a general class of multilevel selection
with transient compartmentalization , and its robustness against noise
and mutations. In a second part, time permitting, I will present a recent
theoretical study of cell growth and cell division in a population of growing cells .
