Question
Chapter 15, Problem 15.2CC
Summary Introduction
To explain: The reason due to which hemidesmosomes and the focal contacts are not found on the same cells at the same time.
Introduction: An important role is played by the extracellular matrix in cell-cell adhesion and cell-cell communication. Extracellular matrix provides mechanical support to the cell and it also acts as a medium for cell-cell communication. Cellular adhesion molecules, which are also called CAM are used to regulate cell-ECM attachment. Proteins such as integrins are also involved in cell-ECM attachment.

Is patch-clamp a type of intracellular recording?
During a microscopy exercise in the anatomy laboratory,a student makes the following observations about a tissuesection: (1) The section contains some different types ofscattered protein fibers—that is, they exhibit differentwidths, some are branched, some are long and unbranched,and their staining characteristics differ (some are seenonly with specific stains). (2) Several cell types withdifferent morphologies are scattered throughout the section,but these cells are not grouped tightly together. (3) Theexamined section has some “open spaces”—that is, placesbetween cells and the observed fibers in the section thatappear clear with no recognizable features. What type oftissue is the student observing? Where might this tissue befound in the body?
You are growing up myoblasts, C2C12 cells, to use in a myogenic study. You are using T-150 flasks with a culture area of 150 cm^2 and when confluent contains 2 x 10^7 cells.
Question: You seed a culture of squamous epithelial cells at 8 am on Monday with 1.2 x 10^5 cells. The next day at 8 am you harvest the cells. You know from past studies that the generation time is 26 hours for this cell line. How many cells do you predict you should have on hand?
A) 1.64 x 10^5 cells
B) 4.56 x 10^3 cells
C) 5.23 x 10^10 cells
D) 1.75 x 10^8 cells
E) None of these
