Tutorials in Mathematical Biosciences III : Cell Cycle Proliferation and Cancer This volume introduces some basic mathematical models for cell cycle proliferation cancer and cancer therapy. Chapter 1 gives an overview of the modeling of the cell division cycle. Chapter 2 describes how tumor secretes growth factors to form new blood vessels in its vicinity which provide it with nutrients it needs in order to grow. Chapter 3 explores the process that enables the tumor to invade the neighboring tissue. Chapter 4 models the interaction between a tumor and the immune system. Chapter 5 is concerned with chemotherapy; it uses concepts from control theory to minimize obstacles arising from drug resistance and from cell cycle dynamics. Finally Chapter 6 reviews mathematical results for various cancer models. Modeling the Cell Division Cycle (B. Aguda) Angiogenesis A Biochemical Mathematical Prospective (H. A. Levine and M.
