I have developed a general computational model (called IBCell model) that can represent accurately the structure of various soft tissues and mechanical transformations occurring during the tissue development and maintenance. This model has been applied to simulate the formation of abnormal folds in the human trophoblast bilayer, the development of epithelial cysts and ducts, and the growth of solid tumors, tumoral clones and various patterns of ductal carcinoma in situ. This model is ideally suited to represent small tissue portions, such as those taken from biopsy samples or those grown experimentally in the culture medium, and to simulate cell responses to various environmental factors and treatment protocols. My ultimate research goal is to integrate the IBCell model with the experimental and clinical data to provide a tool for simulating the growth of tumor cells in different tissues and under various external conditions. The model can be adjusted to represent distinct biomechanical properties of the tissue under consideration and can be extended to include distinct biochemical properties of the host cells, therefore it shows a promise in providing a supporting evaluation of the tumorigenic potential of the collected cell samples and in testing in silico various protocols for patient-specific treatment.
