Critical Processes,ability of growing without bound. The condition defining this threshold is that a colony contains cell types for which the maximum branching probability is 0.5 (see Theorem 1). The branching process is then defined as .. We have already seen that a colony with ., . ≤ 0.5 has probability 1 of complet

Results,e. We will emphasize contrasts between colonies originating from stem cells and colonies originating from more mature cells that lack the capability of self-renewal, which in our model are macrophage progenitors. We will also describe the pattern of growth with increasing time in a heterogeneous cul

Conclusions and Extensions, the commitment and differentiation processes that cause the undifferentiated stem cell to develop into a functionally mature hemopoietic cell. Two opposing views of the process have developed: one view proposes that the decision of when, and along what pathway, a stem cell differentiates is preprog

A Multitype Branching Process Model,renewal. Eventually, a progenitor . produce a daughter cell that differs significantly from itself: this process is called .. The fully mature offspring cannot divide and are called .. Thus the three cell types of the model form a natural progression according to increasing maturity and consequent decreasing proliferative potential; ..

Critical Processes,plete growth is infinite. Thus, aspects of finite and infinite growth are observed in a critical process. One might expect that, biologically, the critical case is important, for it possibly approximates the equilibrium situation ..

Despite this fact and considerable research in this field, the design and control of gel-based devices still present some problems due to the their poor mechanica

Catherine A. Macken,Alan S. Perelsonstrates were porous inorganic membranes (Anotec: 0.02 µ) for permeation measurements and silicon wafers for deposition rate, density, and infrared measurements. To ensure a uniform membrane on the porous support a deposit of five times the pore diameter was required. Membranes deposited at 2.45 GHz
