1

What is a bioartificial organ?

a human made device designed to replace, duplicate, or augment functionality of a missing, diseased, or incomplete body part which requires a non-biologic material interface within the living tissue
Does not include transplants from a donor
Can be temporary or permanent
Includes cosmetic devices

2

What is an autograft?

Tissue taken from oneself
Tissue taken. modified, then returned to the same individual
Ex: bone graft, skin graft, coronary artery bypass grafting, ligands tendons
Usually no immune event or rejection

3

What is an allograft?

Transplant of an organ or tissue between two genetically non-identical members of the same species
Most transplants are allograft
Immune rejection event usually occurs

4

What is an isograft?

organ or tissue in which the donor and recipient are genetically identical
minimal chance of immune rejection

5

What is a Xenograft?

transplant of organs or tissue from one species to another
can be extremely dangerous
still in research stages
Porcine heart valve
baboon to human heart

6

What are the four groups of bioartifical organs?

bone/joint replacements
skin/soft tissue like cartilage
internal organs
sensory organs

7

What is tissue engineering?

use of cells, artificial materials, and suitable chemical factors to improve or replace biological functions

8

What is bioprinting?

living cells are precisely printed based on a pattern

9

How are bioartificial organs generated in industry?

Using biomaterials

10

What is regenerative medicine?

use of stem cells to grow an organ in a laboratory setting
