Ratio control in a cascade model of cell differentiation.
نویسنده
چکیده
We propose a kind of reaction-diffusion equations for cell differentiation, which exhibits the Turing instability. If the diffusivity of some variables is set to be infinity, we get coupled competitive reaction-diffusion equations with a global feedback term. The size ratio of each cell type is controlled by a system parameter in the model. Finally, we extend the model to a cascade model of cell differentiation. A hierarchical spatial structure appears as a result of the cell differentiation. The size ratio of each cell type is also controlled by the system parameter.

Back ground: Although the cell differentiation is an inseparable part of development in multicellular organisms, the regulating molecular pathway of it still is not fully defined. In the other hand, apoptosis is a fundamental physiological process which plays an essential role in a variety of biological events during development. Moreover, recent studies have found that apoptosis shows several ...

Use of Adipose Stem Cells (ADSCs), obtained easily in a relatively less invasive manner (abdominoplasty) and characterized by flow cytometry, is a classical approach in stem cell research and clinical aspects. Other techniques such as isolation of the cells from bone marrow aspirates (1) are rather more invasive. Further, it is pertinent to point out that growth rate, differentiatio...
