Characterizaing the growing medium of living cells as a dynamical system

摘要

The dynamics of the extracellular medium properties are considered to be closely to biological systems' behavior, taking into account the effects of cellular ensembles evolution on growing medium parame- ters. The study emphasizes the existence of a specific (nonlinear) pattern of the evolution of the extracellular medium conductivity for various cellular suspensions in relation to different stress conditions, cell concentration and types of stirring, as well. The possibility is stressed to determine the cellular population status (including the effect of different stress factors) by means of time series of extracellular medium physical parameters (i.e. conductometric measurements).
