Unformatted text preview: EN 585.629 Cell and Tissue Engineering Module 04: Tissue Organization and Dynamics Assignment Total Point Value = 30 Due by midnight on Day 7 of Module 4 This should be submitted to Blackboard as a pdf. 1. Name that tissue and structure! Assign every word from the word bank below to an image or structure within an image. Please use arrows and circles to point to the structure you are labeling when necessary. Note there are 2 bonus images. Correct identification of the structure/tissue is worth 1.5 bonus points each. Cilia Microvilli Skeletal muscle Columnar epithelium Liver sinusoid Myelin Neuron Simple squamous epithelium Stratified squamous epithelium Stratified cuboidal epithelium Elastin Cryptus Basement membrane EN 585.629 Cell and Tissue Engineering BONUS IMAGES EN 585.629 Cell and Tissue Engineering 2. Atherosclerosis (“hardening of the arteries”) is a disease hallmarked by the build-­‐up of plaques in blood vessels. These plaques make it more difficult for blood to flow, which blocks the vital delivery of nutrients to downstream tissue. Complications from atherosclerosis include clots, heart attack and stroke. This disease can manifest in many locations including the coronary artery (when its termed “coronary artery disease”), the cerebral or peripheral vasculature. One way to treat extreme coronary artery disease is through surgery – a Coronary Artery Bypass Graft (CABG). In this surgery a healthy artery from elsewhere in the body is taken and use to bypass the segment of blocked vessel. The disease can become so progressed that it necessitates quadruple or even quintuple bypasses and typically the patients in this state do not have enough healthy vessels to sacrifice (see image where purple vessels indicate typical locations of bypass for the red coronary arteries). A. What is the most common alternative vessel used when there are no arteries left for CABG? B. What are the problems with this solution? What properties of this vessel are unmatched to the needed function? Please describe differences in both form and function. C. Why does this not end up being a problem for many patients in the long run? D. Describe 3 desirable design properties of tissue engineered blood vessels.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
