Fоr eаch theоry yоu choose (from two different chаpters), аnswer these questions: Who created this theory? When and where was it developed? Why was it developed? What problem or idea was the theory trying to explain? What was happening in psychology or society at the time? How did this theory influence society or psychology?

Whаt tissue type did yоu chооse? Fаbricаtion/Manufacturing State the specific stiffness and pore size ranges/averages required for your tissue type. State one more important criteria your scaffold must meet for this specific tissue type. (must be specific to your tissue type— biocompatible and good mass transport are not specific and is therefore not a correct response here) Choose specific materials and state why you would use the chosen materials for this tissue type. (decellularized tissues are not allowed) What are the predominant ECM biomolecules of this tissue type? How can you incorporate them? (at least one ECM) Does this material degrade? By what method? (be specific with type of degradation and erosion mechanism) If not, how will you modify it so it does degrade, and how does the modified material degrade? How can you tune degradation to match regeneration of tissue? (be specific—how to slow it down, how to speed it up and what relative rate do you need?) Choose a specific method of scaffold fabrication and state why this method synergizes with the needs/functionality of your chosen tissue. State one specific biomolecule (growth factors, cytokines, or hormones that are normally found in the body with this tissue type, and is NOT an ECM protein—include ECM proteins in your material choices instead) that promotes your tissue’s successful regeneration, state why it is important, and state how you will incorporate it into your scaffold. (just stating “added to scaffold” is not enough—you must state specific techniques discussed in lecture. See drug loading methods and bioconjugation methods from the lectures) How is the biomolecule released? Choose one scaffold design parameter that can be modified to promote your tissue’s successful regeneration, state why it does, and state how you will modify this parameter (i.e., pore size, surface chemistry, topography, etc.). Choose a specific cell type to use with or within your scaffold, state the source of the cell, and why you are choosing it. If you choose to start with stem cells, make sure you specify how you plan to differentiate them into the appropriate cell type, and state what cell type/s you need for your tissue type. Choose a specific bioreactor to encourage successful development of your scaffold and state why the selected tissue and scaffold design benefit from this bioreactor.
