1. I want to PICK a specific cell type mainly used for gelatin based biomaterial used in tissue engineering for hearing research.

I need to choose a specific and precise size and dimensions for gelatin based biomaterial in tissue engineering for hearing research or the best fit.

Tissue engineering is a promising approach to replace lost or damaged tissues and reduce the need for organ transplantations. organs (heart, lung, etc.) can be decellularized and repopulated with the patient’s own cells. Briefly describe the main pros and cons of this approach. How would it compare to using a synthetic biomaterial seeded with cells (pros and cons)?

Find a research lab or company that is doing tissue engineeringor regenerative medicine.. Please briefly address the followingquestions about your company:
- What type of research do they do?
- What is the impact of the research?
- What are the ethical issues involved?
- Would you want to work with this group, and why?

The four types of resolution response after implantation of a device/biomaterial are

(i) extrusion,

(ii) resorption,

(iii) integration, and

(iv) encapsulation.

What type of resolution response occurs with each of the following device/biomaterial (note: in some case, more that one type of resolution is possible): a. Splinter

b. Degradable tissue engineering scaffold

c. Titanium bone screw

d. Degradable meniscal arrow (used to repair meniscal tears)

e. Breast implant

f. Artificial heart valve leaflet

g. Catheter h. Surface scar tissue (scab)
