Project 1. Mathematical modelling of morphogenesis and regeneration (N.Morozova, R. Penner, C. Soule, A. Tosenberger). The main goal of this project is creating a model which provides a proof of concept for a patterning towards an encoded target morphology and helps to formulate the assumptions necessary for regeneration of cellular structures.
Project 2. Mathematical modelling of cancer stem cells population dynamics (M. Gromov, N. Morozova, C. Soule) Cancer stem cells (CSC) are present at a low percentage in many tumors and are thought to be responsible for tumor relapses following conventional cancer therapies. Most intriguingly, the proportion of CSCs returns to its original level after (almost) any perturbation of proportion of cell populations, as shown in vitro by many experimental teams. This phenomenon still remains to be explained. We suggest a mathematical model of cancer cell population dynamics, based on the main parameters of cell population growth, such as the proliferation rates, the rates of cell death and the proportions of the possible scenarios of cell divisions (symmetric or asymmetric) in stem and non-stem cancer cells. Analysis of this model helps to elucidate some important rules, underlying cancer stem and non-stem populations' behavior. As a practical application, the results of the modeling may provide a mean to evaluate the success of a treatment based on the properties and dynamics of cancer stem cell population in a particular type of cancer.

Development of the model of regeneration of biological organisms. Biological cell structures are considered as ensemble of mathematical points on the plane. Each cell produces a signal which propagates in space. It is received by other cells. Total signal received by each cell forms a signal distribution defined on the cell structure. This distribution characterizes the geometry of the cell structure. If a part of this structure is removed, then remaining cells have two signals. They keep the value of the signal which they had before the amputation (memory), and they receive a new signal produced after the amputation. Regeneration of the cell structure is stimulated by the difference between the old and the new signals. It is stopped when the two signals coincide. The algorithm of regeneration contains certain rules which are essential for its functioning, being the first quantitative model of cellular memory that implements regeneration of complex patterns to a specific target morphology. Correct regeneration depends on the form and on the size of the cell structure and on parameters of regeneration.
Modeling of tissue growth with a deformable cell model. Each cell represents a polygon with particles located at its vertices. Stretching, bending and pressure forces act on particles and determine their displacement. Pressure dependent cell proliferation was considered. Various patterns of growing tissue are observed.

Model of elastic cells for simulation of root growth was developed. The model consists of three cell types and takes into account dynamics of initials which provide for development of vascular cylinder. This model can be regarded as a first approximation for simulation of root meristem development. The model allows to make some hypothesis on the rules of cell divisions. Among them the relative rates and angles of divisions for different initials, the necessity. The model was tested to simulate auxin distribution under the mechanism of the reflected flow.

Development of a new multi-agent model is used to describe blood cell population dynamics in the bone marrow. The model takes into account cell proliferation, differentiation and apoptosis, as well as their motion due to the mechanical interaction and cell communication. Some possible explanations of the mechanism for recovery of the system under important blood loss or diseases such as anemia or leukemia are given. Leukemia development in the bone marrow taking into account intro-cellular and extra-cellular regulation for normal and malignant cells was studied.

Development of model of a binary miscible liquids. The model is based on the Navier-Stokes equations with the Korteweg stress. In particular, there exists a miscible analogue to the Marangoni convection where the temperature gradient is applied along the transition zone between two fluids. Convection also appears if instead of the temperature gradient the case where the width of the transition zone varies in space was considered. Development of a numerical method and programming code for simulation of interaction in binary miscible liquids. The basic conclusion of the numerical simulations is that transient capillary phenomena in miscible liquids exist and can produce convective flows sufficiently strong to be observed experimentally. Several configurations corresponding to the microgravity experiments planned for the International Space Station.
