- List the main types of collagen and their tissue location.arrow_forwardTumors associated with breast cancer usually arise from either epithelial cells or fibroblasts. Because optimal treatment differs depending on the cellular origin of the tumor, it’s important for doctors to determine which cell type is present in a tumor. Unfortunately, the distinctive morphology of epithelial cells is lost when they become cancerous, so this determination cannot be made based on cell shape alone. How might determination of the class(es) of intermediate filaments present in tumor cells aid a doctor in figuring out which cell type is involved in the tumor?arrow_forwardThe trans epithelial electrical resistance (TEER) is a characteristic property of an epithelium. Which of the following statements best describes the TEER? a.) A high trans epithelial electrical resistance (TEER) is an indicator of a leaky epithelium in which paracellular diffusion of solute is likely to be high b.) A high trans epithelial electrical resistance (TEER) is an indicator of a tight attachment between the epithelium and the basement membrane in which diffusion of solute across the basolateral surface is likely to be low c.) A high trans epithelial electrical resistance (TEER) is an indicator of a tight epithelium in which paracellular diffusion of solute is likely to be lowarrow_forward

- Discuss the following statement: “if plant cells contained intermediate filaments to provide the cells with tensile strength, their cell walls would be dispensable.”arrow_forwardFibroblasts are motile cells that “creep” about in the connective tissue of the body where they play a number of roles, including secretion of the extracellular matrix and initiating certain wound healing events. These cells do not usually have microvilli nor do they express the actin-binding protein villin; both of these properties are characteristic of certain epithelial cells, such as those lining the intestine and kidneys. Remarkably enough, however, if one artificially engineers fibroblast cells to produce the villin protein, microvilli form on the fibroblasts. Given what you know about the function of villin, why might this striking change in cell morphology occur?arrow_forwardAnalogs of hemidesmosomes are the focal contact sites, which are also sites where the cell attaches to the extracellular matrix. These junctions are prevalent in fibroblasts but largely absent in epithelial cells. on the other hand, hemidesmosomes are prevalent in epithelial cells but absent in fibroblasts. In focal contact sites, intracellular connections are made to actin filaments, whereas in hemidesmosomes connections are made to intermediate filaments. Why do you suppose these two different cell types attach differently to the extracellular matrix?arrow_forward
