1. Transgenic Animals
Introduction

2. Techniques to develop transgenic animals
Started in the 1970,s and continued to improve.
Become important tools for biomedical research
Economical way to produce many human substances such as hormones
In the future may help with organ procurement with transgenic organs decreasing the shortage of human organs for transplantation

3. Transgenic animal studies are helping to set the stage for gene therapy in humans
In regards to human organ rejection; Scientist have developed ways to hide some of the markers on pig organs so the human immune system does not recognize the pig organ as foreign.

4. Biotechnology is a collection of scientific techniques
Use living cells and molecules to make products & solve problems
By using animals, plants and bacteria biotechnology allows us to enhance our health, our environment and our food supply

5. History
For thousands of years humans have conducted selective breeding to improve our livestock
Controlled plant pollination to produce better crops
Microorganisms to bake bread
Brew beer
Make cheese

6. DNA & Biotechnology Transferring specific genes from one species to another
Allows for the production of microorganisms to produce human hormones: ex: insulin for diabetes
Improve livestock and crops

7. Transgenic organisms defined
Organisms which contain other species genes within their chromosomes
First transgenic organisms were bacteria; the simplest forms of life
First studied by molecular biologist
Advantages:
Reproduce quickly by cell division called (mitosis)
Easy to grow in Laboratory setting.

8. Pharmacy settings Produce human proteins such as insulin for diabetes
Human growth hormones for those humans deficient
Interferon's for immunity, antiviral and possible treatment of certain cancer anticancer abilities

9. Potential of using transgenic techniques in animals can lead to:
Models for human disease
Improve the quality and health of livestock
Research and development of pharmaceuticals
Source of organs for humans with lesser chance of rejection by humans immune system
